Fieldbus coupler 750-342
Data exchange
Modular I/O System
ETHERNET TCP/IP
The input bytes D0 and D1 form the 16 bit reading of counter 1 and the input
bytes D2 and D3 form the 16 bit reading of counter 2.
When setting the counter, the load value of counter 1 is transferred in the out-
put bytes D0 and D1. The load value of counter 2 is transferred respectively in
the output bytes D2 and D3.
