I am new to OpenAPC and I am look for instruction on how you add tags from a PLC, or what OpenAPC calls a PLC tag (external tag)? I have tried searching the manual for tags, tagnames, tag names, communications, OPC... I think from what I have found so far that I need to use a plug-in to get data from a device but where does it go after that? How do I recall a tag for use on the graphics?
Either a direct answer or read chapter "XX" would be appreciated,

Trent,
welcome to the OpenAPC mailing list.
I'm not sure what you mean with "tags" exactly, but I guess it is something PLC-specific, an extension of one of the languages used within a PLC (some kind of placeholder/variable that maps to an address/device).
OpenAPC (or better: ControlRoom) works in an different way, there you have flows of data from one logical or IO element to an other. The concept of tags is not used, a device is represented by a plug-in that accesses exactly this device.
For communication with a PLC you have to find out which interfaces/protocols this PLC supports (Ethernet, MODBUS,...) and then have to use the appropriate plug-in. This plug-in itself will provide data from that device or send them back to it.
With kind regards
Jim
