Control and Status Byte
Channel 1
Process data mode
Control byte 1 (for process data mode)
The control byte 1 (CB1) is located in the output image, and is transmitted from the controller to the terminal.

| CB1.7 | RegAccess | 0bin | Register communication off (process data mode) |
| CB1.6 to CB1.2 | - | 0bin | reserved |
| CB1.1 | CaliDisReq | 1bin | Blocking automatic calibration |
| CB1.0 | StartManCali | 1bin | start manual calibration |
Status byte 1 (for process data mode)
The status byte 1 (SB1) is located in the input image, and is transmitted from terminal to the controller.

| SB1.5 / SB1.4 | StateThreshold2 | 00bin | Threshold 2 is not activated via bit R32.10 of feature register |
| 01bin | process data is lower than Threshold 2 | ||
| 10bin | process data is greater than Threshold 2 | ||
| 11bin | process data is equal to Threshold 2 | ||
| SB1.3 / SB1.2 | StateThreshold1 | 00bin | Threshold 1 is not activated via bit R32.9 of feature register |
