Section 8-6 Communicating between OMRON PLCs Commands Addressed to CS/CJ-series CPU Units The following table provides a list of FINS commands that can be processed by a CS/CJ-series CPU Unit. For details, refer to the CS/CJ-series Programmable Controllers Communications Commands Reference Manual (W342). For details on FINS commands that can be processed by the EtherNet/IP Unit or built-in EtherNet/IP port, refer to Appendix E FINS Commands Addressed to EtherNet/IP Units or Built-in EtherNet/IP Ports. Usage I/O memory area access Command code MR SR Name 01 01 MEMORY AREA READ 01 02 MEMORY AREA WRITE 01 03 MEMORY AREA FILL 01 04 MULTIPLE MEMORY AREA READ 01 05 MEMORY AREA TRANSFER 02 01 PARAMETER AREA READ 02 02 PARAMETER AREA WRITE 02 03 PARAMETER AREA FILL (CLEAR) 03 03 03 04 06 07 08 01 PROGRAM AREA READ PROGRAM AREA WRITE PROGRAM AREA CLEAR RUN 04 02 STOP Machine configura- 05 tion reading 05 01 02 CPU UNIT DATA READ CONNECTION DATA READ Status reading 06 06 01 20 CPU UNIT STATUS READ CYCLE TIME READ Time data access 07 01 CLOCK READ 07 02 CLOCK WRITE Message display 09 20 MESSAGE READ/CLEAR Access rights 0C 01 ACCESS RIGHT ACQUIRE 0C 02 ACCESS RIGHT FORCED ACQUIRE 0C 03 ACCESS RIGHT RELEASE 21 21 21 01 02 03 ERROR CLEAR ERROR LOG READ ERROR LOG POINTER CLEAR Parameter access (registered I/O tables, routing tables, etc.) Program area access Operating mode changes Error log Function Reads the contents of consecutive I/O memory area words. Writes the contents of consecutive I/O memory area words. Writes the same data to the specified range of I/O memory area words. Reads the contents of specified nonconsecutive I/O memory area words. Copies the contents of consecutive I/O memory area words to another I/O memory area. Reads the contents of consecutive parameter area words. Writes the contents of consecutive parameter area words. Writes the same data to the specified range of parameter area words. Reads the UM (User Memory) area. Writes to the UM (User Memory) area. Clears the UM (User Memory) area. Changes the CPU Unit’s operating mode to RUN or MONITOR. Changes the CPU Unit’s operating mode to PROGRAM. Reads CPU Unit data. Reads the model numbers of the device corresponding to addresses. Reads the status of the CPU Unit. Reads the maximum, minimum, and average cycle time. Reads the present year, month, date, minute, second, and day of the week. Changes the present year, month, date, minute, second, or day of the week. Reads and clears messages, and reads FAL/FALS messages. Acquires the access right as long as no other device holds it. Acquires the access right even if another device already holds it. Releases the access right that has been acquired. Clears errors or error messages. Reads the error log. Clears the error log pointer. 235
