CMND(490) transfers the specified number of bytes of FINS command data
beginning at word S to the designated device through the PLC's CPU Bus or
over a network. The response is stored in memory beginning at word D.
Local node
CMND(490) can be used to transmit command data to a particular serial port
in the destination device as well as the device itself. CMND(490) operates just
like SEND(090) if the FINS command code is 0102 (MEMORY AREA WRITE)
and just like RECV(098) if the code is 0101 (MEMORY AREA READ).
The CPU Unit executing CMND(490) can send a FINS command to itself
(except for CS-series CS1 CPU Units prior to V1@). Use the following control
data settings to achieve this.
• Destination network address (bits 00 to 07 of C+2): 00 Hex (local network)
• Serial port No. (bits 08 to 11 of C+2): 0 Hex (not used)
• Destination unit address (bits 00 to 07 of C+3): 00 Hex (CPU Unit)
• Destination node address (bits 08 to 15 of C+3): 00 Hex (local node)
• Number of retries (bits 00 to 03 of C+4): 0 Hex (this setting is invalid; set it
to 0)
