Hi,
has anyone ever setup an Adam 4572 Modbus TCP/IP to Modbus serial convertor?
I am trying to use one with a Red Lion DSPSX but cannot establish comms.
I can get the Red Lion talking to my PC when I run a modbus slave simulator (red lion is the master). But if I run a Master simulator on my PC and connect directly to the convertor I cannot get comms.
I have connected my Red Lion to the Adam convertor and read the serial output from the serial side and get
00FC000000000000F8000000F8000000F8000000F8000000E000000000000F8000000E00000 and so on...
I do not get the message I expect to see which is address my node 4, to read holding register 27 for a length of 2.
thanks
So I would expect 0403001A0002**** where the stars are the CRC.
