kkoen Posted December 11, 2019 Share Posted December 11, 2019 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 Quote Link to comment Share on other sites More sharing options...
