ET 200M
154
Operating Instructions, 12/2008, EWA-4NEB780600602-08
Parameterizing the edges
●
Time stamp with edge 0 → 1:
With a signal change on the digital input of 0 → 1 a signal message with signal status 80h
(incoming) is stored in the data record (DS 100 to 114).
●
Time stamp with edge 1 → 0:
With a signal change on the digital input of 1 → 0 a signal message with signal status 80h
(incoming) is stored in the data record (DS 100 to 114).
Example
For a fully connected ET 200M (8 digital inputs with in each case 16 digital inputs) the data
record 240 has a total of 50 bytes for the configuration of the time stamp.
Return values on DS_WRITE
Possible return values on writing a data record can be obtained in accordance with the DPV1
standard.
