SR391–SR397 correspond to SR220–SR226. The difference between SR220–SR226 and SR391–SR397 is
that the former uses the binary-coded decimal while the latter uses the decimal system. For example, December
is represented as 12 in SR392 while it is represented as 1100 in the binary-coded decimal. Refer to Chapter 6
for more information on the real-time clock.
5. Communication functions
 SM96–SM107, SM209–SM212, SR201–SR202, and SR209–SR216
SR215 and SR216 record the communication port protocol on the PLC. The following table lists the functions
represented by the interface codes.
Code
Function
The FCOPM function card only is only supported as Function Card 2.
When the communication port protocol for the PLC is RS485, RS232, or RS422, then SR209 records the
communication format of the COM1 port on the PLC, and SR212 records the communication format of the
COM2 port on the PLC. The following table lists the settings for the communication protocols. Refer to Chapter
6 for more information on the communication instructions.
