Hi Evgeniy .
I am Using Owen Communication library 3.5.11.3 with SPK110M01.
When Using Function block MB_SerialRequest (FB) with RS-485 port, I do not understand tTimeOut timer functionality. Because When Setting tTimeout := T#100ms, function waits 100ms and gives TimeOutError when reading bigger amount of data blocks that need more than 100ms for completing request task(for example 64 bytes, RTU,9600bps) , I think function block must return TimeOutError : If no response returned in 100ms or Function can calculate approximately time to complete tasks by using relativity by uiDataCount with Baudrate that shown on related hCom port. Thanks.
