AS Series Programming Manual is cleared to zero. If the value of the second in the real-time clock is in the range 30–59, the minutes value increases by one, and the seconds value is cleared to zero. This table lists the corresponding functions and values of SR220–SR226 and SR391–SR397. _2 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. 4.
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. 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.
