Hi Friends,

I am facing some problem in Simotion D435-2 Controller. After switch on the panel power Simotion not go to RUN mode. Instead it is in STOP mode only. In diagnostic buffer it shows that  "Error occurred while reading the IO variable". 

Kindly suggest me to solve this issue.

Hi Christoph,

I called empty program in Execution Fault Task. But still Simotion in Stop mode after Power Restart.

Please suggest me to solve the issues.

What you are probably seeing is that your SIMOITION code is executing before your other peripherals have finished their startup routines.  This is especially noticeable when accessing SINAMOCS as the SIMOTION processor starts faster than the SINAMICS processor.  Three solutions:

1. (Silly way, but effective).  In the STARTUP Task, put a _Wait instruction for 5 or 10 seconds.

2. (What I do)  In the STARTUP Task, Read a variable from each peripheral and drive using _GetSafeValue.  If not OK< then _Wait one second and loop again.

3. Use the code generated using the Project Generator application.

Hello to all,

I have the same problem. Does anybodey can help me why simotion does not go directly to RUN mode after power ON. 

Attached is device diagnostic.

Best Regards,

you get a error during I/O Access , use the function _setsafevalue/_getsafevalue to access the i/o

Thanks for the answer. 
However, I already use pStartUpCheck and it does not go to network 10 unless  'gboStartupCheckPeripheralDevicesOK'  is not TRUE. If FALSE, it jumps to the end of the LAD.

Sounds like an error in your peripheral check code then.  One of your stations is not started before the SIMOTION reads it.  This is very common as SIMOTION starts must faster than SINAMICS.

I always have a routine in the Startup Task that reads a variable from each I/O station with _getSafeValue and loops until all are true or a maximum number of loops occur.
