10.6 Handling OP2 errors
OP2 has two types of error messages:
• System messages: The messages can be analyzed using the SYSMSG
key. (refer to Chapter "OP2 error handling).
• Operating messages: The messages are displayed for approx. 3
seconds and then automatically disappear. (refer to Chapter "Operating
messages").
10.6.1 System messages
If OP2 identifies an error during parameterization, initialization or in cyclic
operation, an appropriate error message is entered into the system error
field and the LED in the SYSMSG key starts to flash.
