Problem solved The client modbus cycle time was linked to a task at 500ms. Whereas the channel modbus was at 200ms. Certainly problem of packages synchronisation. I let the client modbus cycle time to be handled by itself (See attachement) --> "Use the bus cyle time parameters" (traduce from french) See attachement

To display the current time, youβll need to retrieve it from the system clock. In CODESYS, you can use the built-in function SysTime to get the current system time. Hereβs an example of how you can use it: VAR dtCurrentTime: DATE_AND_TIME; sTime: STRING(8); END_VAR dtCurrentTime := SysTime(); sTime := TIME_TO_STRING(dtCurrentTime.t); The sTime variable now contains the current time in the format βHH:MM:SSuno online".

The only weird situation i remeber with particular or complete frozen target visu was after the rtc clock was fallen or set back to the past. It looked like after running a while the alarm history database crashed during writing entries at a date lot of years in the past. After setting the rtc clock to actual date/time and deleting the alarm db every thing worked fine. I don't know, if this is/was a problem of our PLC hardware/firmware? Maybe check date/time at your system?

Hello I've made an FB which is a TCP server. It uses the excellent CAA NetServices library. If I have the FB in a task <4ms, then the RT crashes immediately at boot up. If the task >=4ms, it starts and runs perfectly. This is even if the block is not doing anything; just instantiated. Am I missing something silly? Why would a low task time cause this? 4ms is perfectly adequate, but I'm just interested why... thanks PH

Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.
