Swervomotor Posted January 4, 2019 Report Share Posted January 4, 2019 Ver. 1.25.56 MODBUS TCP is active and working when using the "ID" in Field (B) of a Modbus Aperiodic trigger function, it works. When I put the Tag for that same register in the Field (B) it does not work. Expected I guess as the tag is actual data not an address, but it would be nice if this was linked to the ID somehow. The only way I see around this is to have an entire struct of ID numbers with Tags or use a table to search the desired tag and store the corresponding id into a tag. When using the MODBUS APeriodic Indirect Group Trigger to try to get around this, I enter the Group ID entered in the Registers Aperiodic table and it does not work (get a status code 2) The only option this is leaving me is to have to remember all the registers by ID? Registers Periodic work but I need to trigger this register send in the ladder vs sending it over and over again clogging up my network.
