Hi all,


I've got a customer who quite often needs remote support at various sites, and he asked if there was a device I could give him that would allow him to have me connect to a PLC remotely....

Sounds like a good outcome all round!


If I had to guess about why it's not certified, I'd say that it's probably too open to abuse. A CPS has a huge processor overhead when compared to a COP,...

Thanks for the details. I think I'm settled on Red Lion for the HMI side of things. Ignition will still be the main SCADA package, but I don't think edge is the best way to go for standalone HMI's.

WARNING - if that logic isn't done in the safety task, it is not a safety function and is not considered to give any protection.

Sure, it's good practice and a good idea to do regardless. But if...

You can do it, and it's just as easy as the OP suggested. You write an expression in the tag connection, and then you just have to get your syntax right.

I'm not sure that's the "correct" approach to take with safety data, which is potentially why it's not allowed. You shouldn't be externally "zeroing" the safety tags if the connection faults - that...

You'll probably need to get VBA involved. FTView can't tell which client it's running on - you'll need to use VBA to get the PC name, and use that to decide which macro to run

Rung comments are pretty much it. I mean, if I looked at your program and saw 0-1000 being scaled to a drive output, and an input figure of 742, I'd probably assume what was going on correctly. But...
