(Note 1) RS/CS can be selected only when an RS-232C (5-wire) x 1-channel communication cassette (product
number AFP7CCS2) is used.
(Note 2) The modem is initialized at the time of setting (when the power is on, PMGET instruction is executed,
or switching to the RUN mode). Initialization is executed only in the first session. (Excluding when the
power supply is turned off and then on again.)
(Note 3) Settings of [D+14] to [D+21] are only enabled when the communication mode of the COM1 port is PLC
link.
