I'm working on the SFDC (Shop Floor Data Collection) portion of my program. I need to connect a totalizer / counter to a machine(s) and be able to read it's count value from within FileMaker.
I did it many years ago using a counter with a RS485 output and Troi's serial plugin, but I'm hoping to be able to do it a little easier, this time, by using a counter with an ethernet port. Many counters can communicate over ethernet and they seem to use a protocol called Modbus. I know nothing about Modbus. I am hoping for a counter that contains a web server and I just query that.
Has anyone done something like this before?
