6byte of parameter data are available for the configuration data. These
parameters are stored in non-volatile memory and are available after the
unit has been powered off.
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 09h
3 Function-no. channel 1 09h
4 Function-no. channel 2 09h
5 Function-no. channel 3 09h
The assignment of a function-no. to a certain channel happens during
parameterization. The function-no. 00h does not influence the function-no.
stored in the permanent parameterization data.
Assigning FFh deactivates the according channel.

Note!
• The module is preset to the range "±10V voltage"
in S7-format from
Siemens.
• When cross over or underdrive range all modes return the value 0.
