I'm trying to replicate a working FactoryIO simulation that uses the built in ControlIO soft PLC, on a RasPi OpenPLC Modbus device.
All the control functions are working the same as they do in ControlIO, but I can't get the counter to increment.
In ControlIO, I can use their "Numerical Source" to supply a "PV" value on the "Count Up" block, I manually set this to 10,000:
I'm trying to do the same in OpenPLC Editor, but whenever I try to set the "initial value" I get an error. If I run with no initial value set, the counter doesn't increment:
How can I replicate the counter from ControiIO on OpenPLC please?
