16.2 Static signal transfer (DB 50 ... DB 53)
16.2
Static signal transfer (DB 50 ... DB 53)
Static signals can be transferred between PLC I, PLC II by means of DB 50 to DB 53. These
data blocks are set up in each PLC. One is for sending and the other for receiving signals.
Two transfer procedures are available:
•
1 word in 10 ms time frame (time-controlled), i.e. maximum transfer time 20 ms.
•
24 words, cyclic transfer
The transfer is executed by the PLC operating system and is activated automatically with more
than one PLC.
