Hello Everyone,

Please help me with a communication issue between a Weintek HMI and an Allen Bradley Micro850 PLC. The issue happened after uploading and re-downloading the HMI project. The original project version was EasyBuilder Pro V6.09.1, but it was uploaded and downloaded again using V6.10.2.

After this, the HMI stopped communicating with the PLC. Has anyone experienced this issue before, and how can it be resolved?
