Hello,
I am having an issue communicating with a GE Multilin using a Redlion DSP. My goal is to get the RTD values from the multilin and write them to a compact logix l33er using an rtd int array. This is what I have done so far. I am using a rs 485 to rs 232 B&B communications converter which I use to get online with the ge program on the computer. I have attached that to the RS232 port on the DSP. In the DSP I am using the rs232 universal Modbus master with the proper address (I assume) to the multilin. I get both red and green blinking lights on the DSP which to me means I am communicating with the Multilin but when I create a tag to verify I am receiving data I get nothing or n/a. The address I have found for rtd 1 in the 269 plus manual is 40543 but still I receive no data to the redlion. I am attaching my redlion program so far. I have no experience with Modbus so any help would be appreciated. Thank You
