I am working on a quote for a HMI upgrade which will be a Panel View Plus over Ethernet/IP. The PLC is an older SLC 5/05 however it has the latest upgrades for this particular application. What I am confused about is assigning the tags in the Studio 5000 Factory Talk Studio - View Machine Edition. How do you assign the offline tag file in the Factory Talk Linx Communication Setup if there is no *.acd file in the SLC 5/05 program?
