Process image
The power terminal is represented in the process image with 12 bytes of input and output data each. These are organized as follows:
Byte-Offset | Byte-Offset | Format | Input data | Output data |
|---|---|---|---|---|
0 | 0 | Byte | Status-Byte 0 (SB0) | Control-Byte 0 (CB0) |
1 | 2 | Word | DataIN0 | DataOUT0 |
3 | 4 | Byte | Status-Byte 1 (SB1) | Control-Byte 1 (CB1) |
4 | 6 | Word | DataIN1 | DataOUT1 |
6 | 8 | Byte | Status-Byte 2 (SB2) | Control-Byte 2 (CB2) |
7 | 10 | Word | DataIN2 | DataOUT2 |
9 | 12 | Byte | Extended Status-Byte (ESB) | Extended Control-Byte (ECB) |
10 | 14 | Word | not used** | not used** |
*) Word-Alignment: The Bus Coupler places values on even byte addresses
**) The process image is extended by an unused word in the input and output range, so that the power terminal appears like a four-channel analog terminal.
