ofer.yishai Posted October 20, 2015 Report Share Posted October 20, 2015 Hello, I would like to send a program (recipe) to external process controller/programmer (e.g. Eurotherm 3504) via Modbus IP or RS-485. each parameter has its Modbus address and value in a table. The thing is that parameters should be written only once and in a certain order, if the order is not kept then the receiving instrument may not accept some values. I have a few questions: 1. Is the execution order of the remote slave configuration table is strictly kept? (Like if all rows has the same period, and all use the same active bit ) 2. What is the way to write each address only once (and not repetitively every period)? 3. I was thinking to use different "Active" bits configured in each row in a sequence. How can I get a feedback (like "function in progress" falls in Vision series) that will aid to advance the sequencer? (also to reset the active bit in duty and to set the next one). Would it be advised to go this way? Any advice will be appreciated, Thanks Quote Link to comment Share on other sites More sharing options...
