Warning Caution P REFACE -2U SER 9 S M ANUAL MICRO 3 C USER 9S MANUAL This user 9s manual primarily describes MICRO 3 C 9s additional functions not included in the MICRO 3 programmable control- lers. For installation instructions, general specidcations, and common functions shared with the MICRO 3 such as basic and advanced instructions, allocation numbers, and FUN settings, see the MICRO 3 user 9s manual. MICRO 3 C and MICRO 3 Comparison Program Loader for MICRO 3 C To use the expanded capabilities of the MICRO 3 C such as new advanced instructions for communication and comparison and increased data registers, use an upgraded program loader of version 2.00 or later. To check the program loader version, read FUN31 (program loader version readout/hardware check) using the FUN31 and keys on the program loader. To edit user programs for MICRO 3 C , read FUN11 (program capacity and PLC type selection) on the program loader, and set the fourth line in the FUN11 screen to 1 to select MICRO 3 C as the PLC type, using the FUN11, , , , 1, and keys. Since the loader port on the MICRO 3 C uses RS232C communication while the loader port on the MICRO 3 uses RS485, a dif- ferent loader cable is needed to connect the program loader to MICRO 3 C or MICRO 3 . Use loader cable 3C (FC2A-KL3C) to connect a program loader to the MICRO 3 C loader port. A program loader can also be connected to the data link terminals on the MICRO 3 C using loader cable 4C (FC2A-KL4C). In either case, loader protocol must be selected for the loader port or data link terminals using the protocol selector switch. For selection of the protocol selector switch, see page 1-2. Note: The upgraded program loader of version 2.00 or later can also be connected to the MICRO 3 using MICRO 3 loader cable FC2A-KL1 or FC2A-KL2.

A-2 I NDEX U SER 9 S M ANUAL 1-1 1: G ENERAL I NFORMATION Introduction This chapter describes general information about additional functions and specidcations incorporated in the MICRO 3 C . For general information, functions, and specidcations inherited from the MICRO 3 , see the MICRO 3 User 9s Manual. Features MICRO 3 C has upgraded functions for communications. The new functions are particularly useful for modem communica- tion, user communication, and monitoring data communication. User Communication Function MICRO 3 C has an RS232C loader port in place of the RS485 loader port on the MICRO 3 . The more widely applicable RS232C loader port can be directly connected to any equipment with an RS232C communication port. New advanced instructions for transmitting and receiving data make it possible to set up a communication system using various communication formats. The user communication function can be used only in the standard processing mode, not in the high-speed processing mode. Increased Data Registers Since data communication requires more data registers, MICRO 3 C has 500 data registers (D0 through D499) expanded from 100 data registers in the MICRO 3 . All expanded data registers except D499 can be used to program instructions. In the high-speed processing mode, available data registers are limited to 32 (D0 through D31) as with the MICRO 3 . Double-word Comparison of Data Registers Double-word comparison instruction is added to compare data in data registers. Two consecutive data registers designated by a source operand are compared with two consecutive data registers designated by another source operand. When used with a repeat designation, one double-word comparison instruction can execute a maximum of 31 double-word compari- son operations. With a repeat designation, the results of all double-word comparisons can not only be available individu- ally but also be ANDed; so the comparison results can be easily determined even when comparing a large quantity of data. Parts Description The dgure above illustrates the 16-I/O type MICRO 3 C base unit. Function Selector Switch Selects the station function in the expansion or data link system. Analog Potentiometer Sets the analog value for the analog timer, frequency, or pulse width of pulse outputs. MICRO 3 C has only one potentiometer while 16- and 24-I/O type MICRO 3 base units have two potentiometers. Loader Port For connecting the program loader or computer. The loader port can also be used as a user communication port when user protocol is selected with the protocol selector switch. 01 3 7 0 1 2 6 5 4 DATA LINK ASG B 56710 3 7 0 1 2 6 5 4 Protocol Selector Switch Selects the communication protocol for the loader port (loader proto- col or user protocol) and the data link terminals (data link/expansion link or loader protocol). Data Link Terminals For connecting the data link line in the expansion link or data link system. The data link terminals can also be used for connecting the program loader or computer when loader protocol is selected with the protocol selector switch. Communication Enable Button Enables the communication mode selected with the protocol selector switch. When the protocol selector switch setting is changed while the MICRO 3 C is powered up, press this button to enable the new com- munication mode for the loader port and data link terminals. 1: G ENERAL I NFORMATION 1-2U SER 9 S M ANUAL Protocol Selector Switch The protocol selector switch is used to select communication modes for the RS232C loader port and the RS485 data link terminals. When the MICRO 3 C is powered up, the selected communication modes are enabled automatically. If the protocol selector switch setting is changed after the MICRO 3 C is powered up, the new setting does not take effect until the commu- nication enable button is depressed. Communication Protocols for Loader Port and Data Link Terminals Loader protocol: The protocol used for communication between MICRO 3 C and program loader or CUBIQ on computer. User protocol: The protocol used for user communication instructions (RS232C) Data link protocol: The protocol used for communication in the expansion link or data link (RS485). Note 1: When the protocol selector switch is set to 4, the communication parameters for the loader port are arbitrarily set to the default values of FUN8 (loader port communication mode setting); baud rate 9,600 bps, terminator code 0D, 7 data bits, even parity, 1 stop bit, and receive timeout 500 msec. Any change in FUN8 values does not take effect. The communi- cation parameters for the data link terminals using the loader protocol are dxed and the same as the FUN8 default values. Note 2: When the protocol selector switch is set to 5 through 7, the ERR1 indicator on the MICRO 3 C blinks and the MICRO 3 C does not start to run. Communication Enable Button While the MICRO 3 C is powered up, pressing the communication enable button for more than 4 seconds until the ERR1 indicator blinks once makes the MICRO 3 C read the settings on the protocol selector switch and function selector switch. Then the MICRO 3 C updates the communication modes for the loader port and data link terminals. This button is useful when you want to change the communication mode without turning power off. Function Selector Switch When the protocol selector switch is set to 0 or 1, the data link terminals can be used for expansion link or data link com- munication. Then the function selector switch selects the station function for each MICRO 3 C in the expansion link or data link system. The function of the function selector switch on the MICRO 3 C is the same as that on the MICRO 3 . When the pro- tocol selector switch is set to 2 through 4 to select loader protocol for the data link terminals, the function selector switch setting has no effect.

Selecting Communication Mode Set the function selector switch and the protocol selector switch to select a desired communication mode for the loader port and data link terminals. After changing the settings of the function selector switch and protocol selector switch while the MICRO 3 C is powered up, press the communication enable button for more than 4 seconds until the ERR1 indicator blinks once; then the new communication mode takes effect. When the MICRO 3 C is powered up, the MICRO 3 C checks the settings of the function selector switch and protocol selector switch and enables the selected communication mode auto- matically. You have to press the communication enable button only when you change the communication mode while the MICRO 3 C is powered up. Connecting Program Loader to the Loader Port When connecting a program loader to the loader port on the MICRO 3 C , set the protocol selector switch to 0, 2, or 4 to select loader protocol for the loader port. Use the loader cable 3C to connect the program loader to the MICRO 3 C loader port.

When using a link function, the function selector switch and protocol selector switch have to be set and the FUN settings may be required. For details of these set- tings, see Expansion Link Function and Data Link Function in the MICRO 3 User 9s Manual and Computer Link 1:N Com- munication on page 7-1 in this manual. The expansion link cannot be used in the data link system. Expansion Link System The expansion link system consists of two MICRO 3 C or MICRO 3 base units connected through the data link terminals using the optional expansion cable FC2A-KE1 (250 mm/9.84" long) or a shielded twisted pair cable as shown below. The cable for the expansion link system can be extended up to 200 meters (656 feet). Every MICRO 3 C or MICRO 3 base unit can be used as an expansion station. Data Link System The data link system consists of one master station connected to a maximum of six slave stations to communicate control data for distributed control. Every MICRO 3 C or MICRO 3 base unit can be used as a master or slave station. When a slave sta- tion performs communication at 19,200 bps through the loader port, multi-stage comparison instruction HSC1 cannot be used at the slave station. Computer Link System In the computer link system, a personal computer is connected to one or a maximum of 32 MICRO 3 C base units to control the operation of all MICRO 3 C base units. The 1:1 computer link system requires the computer link cable 4C (FC2A-KC4C) or computer link cable 6C (FC2A-KC6C). The 1:N computer link system using MICRO 3 C base units requires RS232C/ RS485 converter FC2A-MD1 and cables; computer link interface unit FC2A-LC1 is not required.

Loader Port Communication SpeciKcations User Communication Mode SpeciKcations When the protocol selector switch is set to 1 or 3 to select user protocol for the loader port, the MICRO 3 C can communicate through the loader port with external equipment which has an RS232C port, such as a computer, modem, printer, or bar- code reader. Using transmit and receive instructions for user communication, user programs can be created to match the communica- tion protocol of the equipment to communicate with. Determine the possibility of communication referring to the user communication mode specidcations described below: Standards EIA RS232C Maximum Cable Length 15m (49.2 ft.)

The communication parameters using the loader protocol for the data link terminals are dxed to the same values as the FUN8 (loader port communication mode setting) default shown below and cannot be selected unlike the communication through the loader port. Data Link Terminal Communication Parameters (Loader Protocol) When the protocol selector switch is set to 2 or 4, the MICRO 3 C can perform loader communication through both the loader port and data link terminals at the same time. If data write operation (write N bytes or write 1 bit) is attempted to the same operand through both the loader port and data link terminals at the same time, the command through the data link termi- nals has priority although communication error does not occur at both ports. 1.While a user program is written through either the loader port or data link terminals, a user program cannot be written through the other port. The prior write user program operation is executed normally, but the subsequent write user program operation results in a protect error. 2.While a user program is written through either the loader port or data link terminals, a user program cannot be read through the other port. The prior write user program operation is executed normally, but the subsequent read user program operation results in a protect error. 3.A user program cannot be read through either the loader port or data link terminals if a user program is written through the other port before the read user program operation is completed. The subsequent write user program operation is executed normally, but the prior read user program operation may fail to read the complete user program and result in a CRC error.

D490 DSR control signal option When group 2 is enabled as expansion control data registers, D490 is used to control data eow between the MICRO 3 C and the remote terminal depending on the DSR (Data Set Ready) signal of the remote terminal. The DSR signal is an input to the MICRO 3 C to determine the status of the remote terminal. The remote terminal informs the MICRO 3 C using DSR whether the remote terminal is ready for receiving data or is sending valid data. The DSR control signal option can be used only in the user protocol to communicate through the loader port. D490 = 0 (system default): DSR is not used for data eow control. When DSR control is not needed, set 0 to D490. D490 = 1: When DSR is on, MICRO 3 C can transmit and receive data. D490 = 2: When DSR is off, MICRO 3 C can transmit and receive data. D490 = 3: When DSR is on, MICRO 3 C can transmit data.

Use this option when eow control of receive data is required. D488 = 5: RTS is turned on or off according to DSR. When DSR is on, RTS is turned on. When DSR is off, RTS remains off. Use this option for returning control signal and acknowledgment when data eow control with the remote terminal is required. D488 = 6 or more: Same as D488 = 0. D487 Reserved D486 RTS control signal ON/OFF timer When group 2 is enabled as expansion control data registers and D488 is set to 0 or 1 to synchronize the transmit data with the RTS signal, D486 is used to set the amount of time to turn on and off the RTS signal before and after transmitting data. The RTS control signal ON/OFF timer can be used only in the user protocol to communicate through the loader port. D486 = 0 through 249 (Increments 10 msec): Any value over 249 is regarded as 249. The maximum timer error is 20 msec + 2 scan time. Example: D488 = 0 (RTS control signal option) and D486 = 5 MICRO 3 C transmits data 50 msec after RTS is turned off and RTS is turned on 50 msec after data transmission is completed. Since a sufdcient amount of time is allowed for the remote terminal after MICRO 3 C has issued RTS, this option is useful when the remote terminal has a slow communication (receiving) speed. "Operating Status and Control Signals When DSR control is used with D490 set to 1 through 4, transmit condition must be satisded within 5 seconds after the DSR signal has turned to allow transmission. If transmit condition is not met within 5 seconds, the transmit data is invali- dated. Then, RTS and DTR take the same statuses as if the data were transmitted. When group 2 is disabled and user communication is used without control signal options, the communication is performed under the same conditions as expansion control data registers are set D488 = 0, D489 = 0, and D490 = 0. Communication Mode MICRO 3 C StoppedMICRO 3 C Running User Protocol DTR and RTS are on, except DTR is off when D489 = 0 RTS is off when D488 = 2 Control signal statuses depend on D488 through D490 options. Modem Mode DTR and RTS are on as standard. Initial settings are: D488 = 2, D489 = 0, D490 = 0 Loader Protocol Control signal options have no effect.

The FUN29 and FUN50 communication monitor functions can be used when the protocol selector switch is set to 3 to select user protocol for the loader port and loader protocol for the data link terminals. While the MICRO 3 C is communicating through the loader port using the user protocol, the communication status or com- munication data can be monitored on a program loader or computer connected to the data link terminals. The communica- tion monitor functions are useful for debugging user communication programs. System Setup FUN29: User Communication Status Readout User communication error data, execution of transmit/receive instructions, and communication parameters can be read using FUN29 on the program loader.

Before using the FUN50 user communication data monitor, make sure of the correct system setup shown on the preceding page. If the protocol selector switch setting has been changed to 3 after power up, press the communication enable button on the MICRO 3 C until the ERR1 indicator blinks once; then the new communication setting is enabled. First bring the FUN50 screen up pressing the keys: To start monitoring, move down the cursor to the asterisk on the second line and set the monitoring ON/OFF to RUN: To move the cursor up or down, press the or key. Pressing the REP key toggles RUN and STOP to start or stop monitoring. When monitoring is started by switching to RUN, monitor data stored in the previous monitoring is cleared from memory. Monitor data can be stored up to 30 screens. When the monitor buffer reaches full capacity, cFULL d is displayed in place of the communication data blocks, stopping communication data monitor. Before displaying the monitored data, drst stop monitoring, then move the cursor down to the colon (:) and start to display the monitored data. To view the next or preceding screen of monitor data, press the or key. A maximum of 30 screens can be displayed. A communication data block consists of transmit and/or receive data. When the interval between communication charac- ters exceeds 20 msec, the communication data block ends at this point and ** are displayed on a new line to mark the beginning of the next communication data block. To return to the FUN50 screen, press the CLR key. To return to the editor screen, press the CLR key again. After the FUN50 user communication data monitor is completed, press the communication enable button on the MICRO 3 C for 4 seconds until the ERR1 indicator blinks once; then normal communication using the program loader is enabled. If the communication enable button is pressed while a user transmit or receive instruction is executed, the execution is aborted and all outputs are forced off.

Using the modem mode, the MICRO 3 C can initialize a modem, dial a tele- phone number, send an AT command, enable the answer mode to wait for an incoming call, and disconnect the telephone line. All of these operations can be performed simply by turning on a start internal relay dedicated to each operation. System Setup To connect a modem to the loader port on the MICRO 3 C , use the modem cable 1C (FC2A-KM1C). To enable the modem mode, make the three settings described below: 1.Set the protocol selector switch to 1 or 3 to select user protocol for the loader port. (See page 1-2.) 2.Enter 6 (7, 14, or 15) to data register D499 to enable expansion control data register service for D486 through D495. (See page 2-5.) 3.Enter 1 to data regis
