New to OpenAPC

[Trent Gillespie]

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
