Hey Guys, long time no post haha. I've got a tricky one here...
I have a MODBUS device I need to write two things simultaneously to to get the required function to work.
I have to write a function code of 2 to register 4104 and key of 35702 to 4105 simultaneously.
I've tried putting the data in as hex or just decimal versions, on a 4 byte / 2 byte. Hair is being pulled out now and I don't have much left :P
I've tried the fixed length option also as it allows you to select number of registers, but I can't work out how to separate the two values.
This has to be something simple but I'm a bit lost with the syntax. Any help would be most appreciated. I'm a bit confused on this one.
