2 9 0 2 1 40 Expected and current FWAPI version are incompatible Update to newer version of PLC firmware 150999144 E2:
2 9 0 2 2 37 - Cycle time is greater than the set watchdog time Change task configuration 150999205 E2:
2 9 0 2 2 38

- Access violation by an IEC task (for example zero pointer) (detail in call hierarchy as of V1.2)

- Exception cannot be assigned to an IEC task

 Correct program 150999206 E2:
2 9 0 2 x >= 4 38

x=2: Exception cannot be assigned to IEC Task

x>=4: Index of the faulty IEC task, Task Index = x - 4

 Correct program 150999334 E2:
2 9 0 x >=4 2 38

x=2: Exception cannot be assigned to IEC Task

x>=4: Index of the faulty IEC task, Task Index = x - 4

 Correct program 151003302 E2: IEC Task 1
2 9 0 x 2 37 Cycle time of IEC task index x - 4 is greater than watchdog time (x = 31 -> IEC task index > 27) Change task configuration 151003301 E2: IEC Task 0

Notes
 

AC500 uses the following interface identification:

14 = I/O Bus, 11 = COM1 (e.g., CS31 Bus), 12 = COM2

FBP diagnosis blocks do not contain this identifier.
 

The assignment for “Device” is as follows:

31 = Module, 1..10 = Expansion 1..10
 

The assignment for “Module” is as follows:

31 = Module or module type (1 = AI, 3 = AO, 4 = DC)
 
In case of module errors, “31 = Module” is reported for the channel.
 
In the current AC500 CPU firmware version, errors reported to the AC500 CPU by the DC505-FBP cannot be directly made visible on the display or in the PLC browser of the Control Builder PS501.
 
Communication Module errors: 1 = UDP DataExchange, 2 = UDP no AC31 Header, 3 = Online Protocol, 4 = Netconfig, 5 = SNTP, 6 = Modbus
