Can a click PLC control my RS232 ascii device?

I am a programmer but new to PLC's. Could a click plc interface to a piece of electronics that has an RS232 ascii based protocol? basically poll the device to mirror it's fields in PLC registers and allow me to change a value in a register and have it sent to the device? i attached the device protocol.

 

it would probably take me a month of learning to figure out if this is even worth trying so any guidance would be very much appreciated.

    You could use a Productivity or Do-more series plc since they both support full duplex.

    Yes you can setup the RS232 port for ASCII protocol on the CLICK.

    oh wow, that sounds like a deal breaker. if there is not way to poll a serial device and read the response i don't see much of a way to use the RS232 port.

      is the software development environment for the productivity different than the click? if so is it user friendly?

      • Durallymax (Customer)

        It's different, same feel as any ladder environment but Psuite is fully tag-based while Click is address based. Most would say Psuite is easier and more flexible with more features. DmD has the most capability/features when it comes to comms related issues.

    DmD is Do More (H2 or T1H cpus)?

  • Indygreg (Customer)

    super helpful. thanks.the BRX looks pretty good and the Do-More Designer looks pretty powerful for receiving and parsing serial data on tcp and rs232.

     

    i wonder if it would be possible to hire someone to spend a few hours to bootstrap me. i have coded and can figure this out eventually but i could probably save days if i worked with someone to implement 1 or two calls to my devices.
