You can set two types of controller error characteristics:
– Hard error characteristic: When an error occurs, the con-
troller switches to the operating mode "STOP"
– Soft error characteristic: When an error occurs, the con-
troller remains in the operating mode "RUN".
Warning
Ensure that valves and outputs are put into a safe status
•
if the stated malfunctions occur.
An incorrect status of the valves and outputs can lead to
dangerous situations!
Note
Please note the following if the outputs are reset after PLC
stop, network interruption or malfunction:
– Monostable valves move to the basic position
– Bistable valves remain in the current position
– Mid-position valves go into mid-position (pressurized,
exhausted or closed, depending on valve type).
Error numbers and types
Table Tab. 3/9 shows PROFINET-specific error numbers and
types.
A list of all CPX-specific error numbers and types can be
found in the CPX system description (P.BE-CPX-SYS...).
Further diagnostic information about the error types can be
obtained. The sections 3.5.2 and 3.5.3 describe access to
these error types (based on Siemens STEP 7).
