The selection voltage (0 = Default) or current (1) is required due to the different reference values for current and voltage.
Bit |
Nibble |
Description |
---|---|---|
0 |
Low-order nibble (4 bit) |
0 = Channel 1: voltage signal 1 = Channel 1: current signal |
1 |
0 = Channel 2: voltage signal 1 = Channel 2: current signal |
|
2 |
0 = Channel 3: voltage signal 1 = Channel 3: current signal |
|
3 |
0 = Channel 4: voltage signal 1 = Channel 4: current signal |
|
4 |
Higher-quality nibble (4 bit) |
0 = Channel 1: 0...20 mA current signal |
5 |
0 = Channel 2: 0...20 mA current signal 1 = Channel 2: 4...20 mA current signal |
|
6 |
0 = Channel 3: 0...20 mA current signal 1 = Channel 3: 4...20 mA current signal |
|
7 |
0 = Channel 4: 0...20 mA current signal 1 = Channel 4: 4...20 mA current signal |
General description for the bit 7-0 assignment
Selection current/voltage Bit 7...Bit 0 |
Meaning |
---|---|
0000000x |
Configure the output 01 in the low-order nibble: Bit 0 is set to 0: Voltage signal Bit 0 is set to 1: Current pre-selection |
000000x0 |
Configure the output 02 in the low-order nibble: Bit 1 is set to 0: Voltage signal Bit 1 is set to 1: Current pre-selection |
000x0001 |
Configure the output 01 by the current pre-selection in the higher-quality nibble: Bit 4 is set to 0: 0x01...0...20 mA Bit 4 is set to 1: 0x11...4...20 mA |
00x00010 |
Configure the output 02 by the current pre-selection in the higher-quality nibble: Bit 5 is set to 0: 0x02...0...20 mA Bit 5 is set to 1: 0x22...4...20 mA |
