I'm trying to interface a Daniel Model 575 GC (2350A controller) to a DeltaV system. I'm using Modbus RTU for the communication, with the GC connected via RS-232 to a RS-485 converter. The converter is then connected to the proper card in the DeltaV system.
With not being too familiar with DeltaV (going through an operator for the setup) and doing this in China (language barrier), I do not know fully what to look for. It appears the there may be a signal between the two, but there is an error (I believe it is for an illegal address). The registers in the GC are setup starting at 2001 in floating point, but in the DeltaV programming starts with a base register of 40001 for trying to read the holding registers.
Does anyone have an idea of what could be done?
