Connections to a SLC 5/01 DH485

(1/2) > >>

RedBinary:
I'm curious if AdvancedHMI has ever been used to communicate with a SLC 5/01 with only a DH485 port? If so, which adapters - PIC or UIC or both?

Archie:
I have connected to the older DH485 processors using a 1770-KF3 module. It is essentially a DF1 to DH485 converter. A PIC module will not work because it relies on software token passing which is very difficult and nearly impossible in .NET

I have never used the UIC module, but it may work if it maps to a COM port.

dmroeder:
I was trying this with a UIC today and was not successful.  I tinkered around with the baud rate and error checking.

RedBinary:
We've ordered a UIC that should be here soon. I'll update once we've gotten it & had some time to play around.

RedBinary:
The UIC-1747 arrived yesterday so I spent a couple of hours & I tried a few things but was also not able to make it work. It will obviously need some driver changes to work directly with DF1 over USB. However, I'm getting ready to look into OPC - which I know nothing at about having just stumbled across it's existence while trying to get it to work with DF1 yesterday.

If there is any willing advice out there on using an OPC interface I'd sure like to hear it! Especially if the advice is "Don't"
