Hi again everyone,
Well, in the process of connecting my various devices to ignition, I discovered that a couple of controllers that my old SCADA system was talking to don’t support Modbus. Crap!
I found a copy of the manual for the controller and it looks like it has some sort of custom protocol for communications. Link to manual: http://www.cszindustrial.com/portals/1/pdf/DII60.0_Manual.pdf
The serial info is in Appendix B, page 101. The juicy details of the protocol start on page 110.
That isn’t the exact controller I have, but the protocol is the same. Is it even possible to connect ignition to this? I’m not clear on the capabilities of the TCP driver or the Serial Module. I can get an Ethernet to Serial adapter similar to the Modbus gateways I’m using for my other serial devices, but I’m not sure how to go about setting up actual communications with this thing, or if it’s even possible.
How badly am I screwed here?
