Wago 750-880

Hello, I am writing a program to collect measurement data from wago 750-495 (POWER MEASUREMENT MODULE) and then send this data to SQL Database via GPRS Modem.

I have written POU for collecting the data and I have also written POU for sending the data to SQL Database. The problem is that both POU's are separate. What I want is to send the data from Power Measurement POU to SQL POU.

How can I do it? Can I link these two files by declaring global variables? or Is there any other way?

Variables from one POU to another can be accessed by preceding the variable name with the name of the POU. For example if your POUs are named PMM and SQL you can access the variable called VoltageR in PMM from SQL as follows:

PMM.VoltageR

Good Luck,
