• Communication information
The communication information indicates the status of the serial link. The three possible states
are:
- Idle: there is no communication
- Busy: communication takes place
- Error: an error has been detected.
The following errors are reported:
- parity error
- overrun error
- framing error
The occurrence of one of these errors is indicated by a number which is displayed on the service
row. A combination is also possible. The error numbers are:
16 = parity error
32 = overrun error
64 = framing error
When a combination of errors occur the sum of the error numbers is displayed.
Example:
When a parity and an overrun error occur at the same time the error number will be 16 + 64 =
80.

If you have an error message in the service row, check first whether the specification parameters
for serial communication are equally programmed in the control and in the connected computer.
