When a signal event occurs (alarm, failure), the following information is transmitted in a single
line through this port to a printer:
Figure 5-44: Protocol Printer, Data Structure
The results are printed each time the measurement value exceeds or falls below the alarm
threshold, in the event of a system failure, in the event of a successful manual reset or a signal
failure. The current status of the input is printed out in accordance with the data structure
shown in Figure 5-36.
5.10.4 Diagnostics / Service (RS 232C)
This port is intended only for internal system testing. (Output of failure messages when the
