Process image
The terminal is represented in the complex process image with 24 bytes of input data and 24 bytes of output data. These are organized as follows:
byte offset | byte offset | format | input data | output data |
---|---|---|---|---|
0 | 0 | Byte | ||
1 | 2 | Word | DataIN1 | DataOUT1 |
3 | 4 | Byte | ||
4 | 6 | Word | DataIN2 | DataOUT2 |
6 | 8 | Byte | ||
7 | 10 | Word | DataIN3 | DataOUT3 |
9 | 12 | Byte | ||
10 | 14 | Word | DataIN4 | DataOUT4 |
12 | 16 | Byte | ||
13 | 18 | Word | DataIN5 | DataOUT5 |
15 | 20 | Byte | ||
