16byte of parameter data are available for the configuration. These
parameters are stored in non-volatile memory and are available after the
unit has been powered off. 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 50ms. During this time,
the measuring value output is 7FFFFh.
The following table shows the structure of the parameter data:
Parameter area:
Byte Bit 7 ... Bit 0 Default
0 Wire break recognition channel 0
Bit 0: 0 = deactivated
1 = activated
Wire break recognition channel 1
Bit 1: 0 = deactivated
1 = activated
Wire break recognition channel 2
Bit 2: 0 = deactivated
1 = activated
Wire break recognition channel 3
Bit 3: 0 = deactivated
1 = activated
Bit 4, 5: reserved
Diagnostic interrupt
Bit 6: 0 = diagnostic interrupt inhibited
1 = diagnostic interrupt enabled
Bit 7: reserved
00h
1 Bit 3 … 0: reserved
CPU-Stop reaction for channel 4
Bit 4: 0 = Set replacement value
*)
1 = Store last value
CPU-Stop reaction for channel 5
Bit 5: 0 = Set replacement value

1 = Store last value
Bit 6, 7: reserved
00h
2 Function-no. channel 0 (see table input ranges) 28h
3 Function-no. channel 1 (see table input ranges) 28h
4 Function-no. channel 2 (see table input ranges) 28h
5 Function-no. channel 3 (see table input ranges) 01h

9 Option-Byte channel 3 (see table next page) 00h
10 Function-no. channel 4 (see table output ranges) 09h
11 Function-no. channel 5 (see table output ranges) 09h
12 High-Byte replacement value channel 4 00h
13 Low-Byte replacement value channel 4 00h
14 High-Byte replacement value channel 5 00h
15 Low-Byte replacement value channel 5 00h

If you want to get 0A res. 0V as output value at CPU-STOP, you have to set the following
replacement values at current output (4...20mA) res. voltage output (1...5V):
E500h for the S7 format from Siemens.
