I have used RSLogix micro starter lite for the first time to write a basic counting application. The PLC is connected to a limit switch that signals the count. This value is displayed via ethernet to a c600 touch screen. I created an L12:1 register, which is the address/tag that is displaying the 32bit count on the PV screen. I want to send this data string via the RS-232 to a PC less than 2m away. I'm getting confused with converters, DH-485 networks, factory talk and all the comms solutions out there that I can't find the appropriate answer. Can I send the contents of this register using the MSG command to a PC easliy. If so how, and what will need to be done on the PC side to receive this string? Is any software driver needed on the PC or will the string be visible via com port.
One more question; the counter value is incremented by one after power down and up again. I can fix this but I'd like to know why it's happening.
Any help would be much appreciated.
