-232ADP or FX

-232ADP can be changed
over to the communication with a programming tool (programming communication) by the following methods.
If the external equipment executes another type of communication while the programming communication is
selected, the PLC sends back "NAK".
1. When changing over using RUN mode and STOP mode
Set the communication format to one of the settings shown below to use non-protocol communication (in
accordance with RS-232C) using the RS instruction while in RUN mode and then use the programming
communication while in STOP mode.
2. When changing over using the RS instruction while in RUN mode
When changing over non-protocol communication using RS instruction to the programming communication
while in RUN mode, set RS instruction to OFF, and then overwrite the communication format (D8120) to
"H0000".
Before starting up RS instruction again, make sure to properly overwrite the communication format (D8120)
used in the RS instruction.
In this setting also, the communication mode can be changed over using RUN mode and STOP mode if the
condition shown in 1 above is satisfied.
3. Caution on using the RS instruction and programming communication together
Do not use the communication setting by parameters. Use the communication format device (D8120).
