Process data mode
Control byte 1 (for process data mode)
Control byte 1 (CB1) is located in the output image, and is transmitted from the controller to the terminal module.
Bit | CB1.7 | CB1.6 | CB1.5 | CB1.4 | CB1.3 | CB1.2 | CB1.1 | CB1.0 |
Name | RegAccess | - | - | - | - | - | - | - |
Bit | Name | Description | |
|---|---|---|---|
CB1.7 | RegAccess | 0bin | Register communication off (process data mode) |
CB1.6 to CB1.1 | - | 0bin | reserved |

CB1.0 | - | 0bin | reserved |
Status byte 1 (for process data mode)
Status byte 1 (SB1) is located in the input image and is transmitted from terminal module to the controller.

Name | RegAccess | Error | StateThreshold2 | StateThreshold1 | Overload | Underload | ||
Bit | Name | Description | |
|---|---|---|---|
SB1.7 | RegAccess | 0bin | Acknowledgment for process data mode |
SB1.6 | Error | 1bin | an internal error has occurred (current process data is no longer valid) |
SB1.5 / SB1.4 | StateThreshold2 | 0bin | Threshold 2 is not enabled via bit R32.10 of the feature register |
01bin | Process data is greater than threshold 2 | ||
10bin | Process data is less than threshold 2 | ||
11bin | Process data equals threshold 2 | ||
SB1.3 / SB1.2 | StateThreshold1 | 0bin | Threshold 1 is not enabled via bit R32.9 of the feature register |
01bin | Process data is greater than threshold 1 | ||
10bin | Process data is less than threshold 1 | ||
11bin | Process data equals threshold 1 | ||
SB1.1 | Overload | 1bin | Process data is greater than specified in register R21. The red error LED of this channel is lit. |
SB1.0 | Underload | 1bin | Process data are less than specified in register R22. The red error LED of this channel is lit. (The calibration is active if SB1.0 and SB1.1 are set simultaneously). |
