Type Communication command
Syntax FINS_COMMS(type, network, node, unit, remote_area,
remote_offset, length, local_area, local_offset, timeout)
Description FINS (Factory Interface Network Service) is a Proprietary OMRON com-
munication protocol. A subset of this protocol has been implemented in
Trajexia. The FINS protocol has been implemented with the intention of
enabling seamless communication with other OMRON devices (PLCs,
HMIs, etc.) and software (CX-Drive, CX-Server, etc.). For more informa-
tion on FINS communication protocol, see the Communication Com-
mands Reference Manual, cat. num. W342-E1, Sections 3 and 5.
Trajexia has built in FINS client capabilities, so it can initiate the FINS
communications with FINS slave devices using
FINS_COMMS . Only
FINS 0101 (Read Memory) and FINS 0102 (Write Memory) commands
are implemented. With FINS 0101, memory can be read from other
devices with FINS server capability. FINS 0102 can be used to write
data to devices with FINS server capability.
This command returns one of the following values, depending on out-
come of the execution:
-1: The command executed successfully.
0: The command failed.
1: Request not sent because the client or the FINS protocol is busy.
2: One or more of the request parameters are invalid.
3: Invalid source memory area.
4: Request was sent, but no response from remote server received
within timeout period.
5: Error response code received from remote server.
