You address those in the SLC/MicroLogix with slashes, so N50:0/0 is the first bit of the first word.

Those Integers also have 'sub-elements', the individual bits that make up the word. N50:0 is the first element, N50:1 is the second element, and so on. In an SLC/MicroLogix, an 'element' is the data type of the data table.ДЇor Integer data tables, each 'element' is a 16-bit word. That's super-common when I was teaching ControlLogix classes I illustrated with Lego blocks. I think you're having some confusion about the word 'elements'. You've not given any part numbers, but if you're suggesting that your Control Logix PLC has an onboard ethernet port, it must be one of the new 1756-L8 CPU's, correct? If so, you will not need a separate ethernet module in the Control Logix chassis - you can communicate directly to the PLC using it's onboard ethernet port.Дo some reading up on explicit messaging and have a play around, if you need a push in the right direction let us know where you're getting stuck and we'll be able to provide some more targeted advice. Yes, you can set it up offline and then download, or MSG communications can be performed online.

The help file gives quite a lot of information and examples on how to set it up and use it.

I'd suggest that you search this forum for threads on setting up MSG instructions, and also just drop one into your program, click on it and press F1. Getting it working is relatively straightforward, but there are a whole lot of things involved in getting it working well and doing it in 'best practice' ways. Welcome to the forum! To communicate between a Control Logix and a Micrologix you will use explicit messaging, i.e.
