MX4 SCADA

Hi, I have used MX Component to interface with my PLC and MX4 SCADA. I have 2 projects that have the same interfacing configuration but only one project can work. Can anyone tell me anything wrong about my MX4 SCADA? Thank you!

Nobody can help with a question like that !! You need to explain what the errors are, what it is and isnt doing etc etc.

Sorry. I am doing a project using powermeter to check the current, voltage and power from a PLC. One project in the MX4 SCADA can communicate with the PLC with MX Component, where it will display all the values such as current, voltage and power from the PLC. However, another project using MX Component cannot display the value. It says server PLC offline. So the error is why the first project can communicate with the PLC while another project cannot communicate with the PLC even though they are both using the same MX Component. Thank you!
