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 0Eh
3 Function-no. channel 1 0Eh
4 Function-no. channel 2 0Eh
5 Function-no. channel 3 0Eh
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.
No. Function Output range
00h Does not affect permanently stored configuration data
04h Current 4...20mA
Siemens S5 format
(two’s complement)
0...24mA
24mA = max. value before over range (20480)
4...20mA = rated range (0...16384)
0mA = min. value before under range (-4096)
06h Current 0...20mA
Siemens S5 format
(two’s complement)
0...25mA
25mA = max. value before over range (20480)
0...20mA = rated range (0...16384)
no under range available
0Ch Current 4...20mA
Siemens S7 format
(two’s complement)
0...22.81mA
22.81mA = max. value before over range (32511)
4...20mA = rated range (0...27648)
0mA = min. value before under range (-6912)
0Eh Current 0...20mA
Siemens S7 format
(two’s complement)
0...23.52mA
23.52mA = max. value before over range (32511)
0...20mA = rated range (0...27648)
no under range available
FFh Channel not active (turned off)
Note!
• The module is preset to the range "0...20mA"
in S7-format from
Siemens.
• When cross over or underdrive range all modes return the value 0.
