    modbus comm errors

    Yes, that works! Only thing is that since the channels are in two different groups now, I can no longer open the channel to see the graph or table view. I can only open the list of channels with all their properties. This is only necesary for debugging, and maybe it has to do with the older DAQ version?
  2. Hi there, Thanks for the support i received in the past, I have a few years of positive experience with azeotech. In my current project i deal with a modbus device. Reading the registers works ok, I have a channel for each register I want to read and have them all set at 0.1s interval. Now, I also need to set some registers and I made a small sequence for that. the button ' zero displacement' invokes this sequence. the registers I want to set all have their own channel as well. This works but only sometimes... with reading every 0.1s I get lots of ' port locked' errors. I quess that i need to pauze the reading for a moment to make room on the bus for setting the appropriate registers. Could you give me a hint on how to solve these issues? Thanks, Koen for legacy reasons, I run this file in DAQfactory 5.87c DirksonWTB_22kN_v1.ctl
