Hi!

anyone knows what I/O server is needed by Wonderware Intouch to access tags from Contrologix5550?

If i am to use Rslinx, how do I access a tag form Intouch 7.1?

Thanks.

For Intouch 7.1, you have to use Wonderware's AB ControlLogix I/O Server (ABCIP) along with RSLinx OEM or Pro. You have to use the old PLC5 addressing scheme in your CLX PLC for it to work. If you don't like this, try a third party IO Server from co's like Top Server (www.softwaretoolbox.com), Kepware server (www.kepware.com), Ingear OPC server (www.ingear.cimquest.com) that allows you to use the CLX tagnames/variables addressing.

If you upgrade to Intouch 8.0 or higher, you can use Wonderware's ABCIP DAServer which doesn't require RSLinx and have the addressing restrictions.
