You have several problems here. What is the purpose of MB 146? Do NOT do conditional subroutine calls. It is also very inadvisable to do conditional Socket initializations, especially here where it is completely unnecessary. Please post your program here. We need to see inside your function blocks to provide any meaningful help.

There are a lot of different files that make all of this work. They are not all updated at the same time. There is no reason the versions numbers would remain in sync.

You can run Remote Operator on a Windows computer and put the computer display on a TV.

Guess what? I found this setting in the Project / Options section. Wish I had seen this sooner. My preference would be for the checkbox to be available in the download dropdown since I don't ALWAYS want to go online after a download, but I'll take it.

This is a great suggestion for @AUTOMAT-MIND.

VisiLogic is free. I'm not sure what happens when you don't register, but if you're having problems, sent a request to support@unitronics.com. They should be able to help you and they are usually very responsive.

You absolutely can with MODBUS TCP/IP. Just use two different sockets.

What PLC and I/O are you using? High Speed inputs will calculate frequency for you.

I'm using UniLogic 1.28.34 and can see no way to add a string variable to the body of an email. Am I missing something? If not, anyone know of a workaround?

What project settings radio button?

Doesn't seem to be any forum that's a great fit for this topic, but placed it in the closest I thought was applicable.

What did you change? If you changed the comm settings for your serial port being used for PC-PLC comms, then you can interrupt the ability to connect from VisiLogic. Go into INFO Mode and check your serial port settings.

Those Snap-In module connections can be a bear. Thanks for getting back with the solution.

In addition to kratmel's excellent advice, are the PLCs the Master or Slave to the SCADA? If Master, then there are some Ethernet System Operand settings that can improve connection recovery. Also, there are some ladder code techniques that will auto-reconnect when the connection is lost. Can you post your program here?

Moved to the correct forum.
