Counter input data (words) 4
Counter output data (words) 8
1.7.5.2.5 Addressing
The module reads the position of the rotary switches only during power-up, i. e.
changes of the switch position during operation will have no effect until the next
module initialization.
1.7.5.2.6 I/O Configuration
The CI542-DP PROFIBUS DP bus configuration is handled by PROFIBUS DP master with the
exception of the slave bus ID (via rotary switches) and the baud rate (automatic detection).
The digital I/O channels and the fast counter are configured via software.
