If I set up a ML1400 as a Modbus RTU slave, and click the extended files tickbox, then set up my files with 200 elements, will the Modbus addressing span those files correctly?
I selected file N20 and 200 elements, so N20:0 = Modbus holding register 1 or 40001, N20:199=40200
Next I want to create a second file N21 with 200 elements.
Will N21:0=40201?
I have seen this done and worked on systems that used 5 files but they were all 256 elements in length so I was curious if that was required and what would happen if I made it a nice round 200 elements each.
I will run a test later this week and update this thread but if someone knows for sure the answer to this, I can prepare my code correctly now before the panels are ready to test.
