PLCs, non-protocol communication (in accordance with RS-232C or
RS-485) using the RS instruction can be changed over to a protocol dedicated to computer link by the
following methods.
The protocol supported by the communication port can be checked in the operation mode display device
(D8149).
1. When changing over using RUN mode and STOP mode
Set the communication format as shown below to use non-protocol communication (in accordance with RS-
232C or RS-485) using the RS instruction while in RUN mode and then use computer link while in STOP
mode.
Set computer link using parameters.
Make sure to set the communication format used in the RS instruction to D8120, and write it before executing
the RS instruction.
2. When changing over using the RS instruction while in RUN mode
When changing over non-protocol communication using the RS instruction to computer link while in RUN
mode, set the RS instruction to OFF, and then overwrite the communication format (D8120) to "H0000".
Set computer link using parameters.
Before starting up the RS instruction again, make sure to properly overwrite the communication format
(D8120) used in the RS instruction.
