Basic Operating Procedure
Section 1-9
• Execute the STUP(237) instruction. The Board or Unit Setup Area can be
changed while the PLC power supply is ON. The STUP(237) instruction
can be used, for example, when a communications sequence for a
modem connection is executed in Protocol Macro Mode to switch the
operating mode to Host Link Mode when a certain condition is estab-
lished. This enables monitoring or programming of the CPU Unit to be
carried out from a host computer. See
Appendix O
Changing Port Set-
tings Using STUP(237).
Executing
Communications
The required data and ladder program are created to perform communica-
tions in the serial communications mode that has been set.
Host Link Communications
Sending C-mode and FINS Commands from Host Computers to PLCs
To send C-mode commands or FINS commands, programs must be created
on the host computer to send commands to PLCs and to receive responses
back from the PLCs. Refer to the
CS/CJ-series Communications Commands
Reference Manual
(W342)
for details.
Sending FINS Commands from PLCs to Host Computers
SEND(090), RECV(098), and CMND(490) can be used to execute slave-initi-
ated communications. Also, programming is required at the host computer to
