Every channel is individual parameterizable. For the parameterization,
10byte parameterization data are available. The parameterization data are
stored permanently and remain also in off mode. By using the SFC 55
"WR_PARM" you may alter the parameterization in the module during
runtime. The time needed until the new parameterization is valid can last up
to 60ms. During this time, the measuring value output is 7FFFh.
The following table shows the structure of the parameter data:
Parameter area:
Byte Bit 7 ... Bit 0 Default
0, 1 reserved 00h
2 Function-no. channel 0 28h
3 Function-no. channel 1 28h
4 Function-no. channel 2 28h
5 Function-no. channel 3 28h
6...9 reserved 00h
For each channel here the function-no. of your measuring function can be
set. Please see the according table.
The function-no. 00h does not influence the function-no. stored in the
permanent parameterization data.
Assigning FFh deactivates the according channel.
