Hello all,
I tried my hands on the software using a test bench and I’ve been enjoying it past 2 months now. I was testing software for upgradation of our screen at our plant but few days ago I encountered a problem that my Ignition Screen can write values but cannot read the values from the PLC. And it overlays an error of green color question mark on every display element. I went through various forums but no help can be found.
If anyone could help me with a solution it would be greatly appreciated.
PLC - MicroLogix1100, Ethernet IP protocol.
Troubleshooting- Checked the communication works well for writing but no read of the present. Deleted all tag database and imported again. But all in vain.
