During a measurement the data is stored in the data input area. The table
above shows the allocation of the data to a measured value as well as the
respective tolerance.
The following figure shows the structure of the data input area:
Data input area:
Byte Bit 7 ... Bit 0
0 High-Byte channel 0
1 Low-Byte channel 0
2 High-Byte channel 1
3 Low-Byte channel 1
4 High-Byte channel 2
5 Low-Byte channel 2
6 High-Byte channel 3
7 Low-Byte channel 3
Note!
Only channels 0 and 2 are used in 4wire systems.
Every channel is individual parameterizable. 10byte are available for the
configuration data. Configuration parameters are stored in permanent
memory and they will be retained even if power is turned off.
The following table show the structure of the parameter area:
Parameter area:
Byte Bit 7 ... Bit 0 Default
0 Diagnostic alarm byte:
Bit 5 ... 0: reserved
Bit 6: 0: diagnostic alarm inhibited
1: diagnostic alarm enabled
Bit 7: reserved
00h
1 reserved 00h
2 Function-no. channel 0 (see table) 28h
3 Function-no. channel 1 (see table) 28h
4 Function-no. channel 2 (see table) 28h
5 Function-no. channel 3 (see table) 28h
6 Option byte channel 0 00h
7 Option byte channel 1 00h
8 Option byte channel 2 00h
9 Option byte channel 3 00h
