dulu Posted February 18, 2015 Report Share Posted February 18, 2015 Please could you explain how works the timing when i use modbus-master RTU. Right after the end of communication with slave (procedure readcoils), data won't update.In memory (MB1200...) there are data from the previous communication. When i try to load them with delay 10 ms then they are updated. what is the guaranteed period of validity of data? Or what should i do to guarantee validity of a data? Task is in attachment. target : V1040 visilogic: 9.7.44 Quote Link to comment Share on other sites More sharing options...
