Hi , I am using 

KAS IDE Version: 3. 00 Build 3, 00, 0, 75985.

AKD-M-MCEC-V01-17-00-000

KAS-PDMM-M-MCEC-3.00.0.75985

 I connect AKD with S7 315 PLC.  Initially after i download the program, PLC  PLC shown the AKD device connection not stable.

afterward i try to increase the update time to 8 ms and  watchdog to 7 cycle..form TIA portal as this community suggested, it seem the AKD device connection stable from TIA portal view.. 

But form KAS IDE, always there is error message

If i disconnect TIA portal online status, the error message stop generated. Should i continue testing to increase the update time Or watchdog time (Which one better) until it stable? what are the advice able setting  limit or there is other special setting i need to take care?

I have another error. message
