I was having a lot of difficulty determining the addressing of point io vice embedded i/o and this helped. My rack is using a IA4 card, so 4 inputs, but when I drill down to obtain the specific inputs i need, the controller tags point to 8 Bools and 8 addressed inputs. Is this because it's a SINT, 8 pats and only 4 are available despite listing 8?
Hi Todd, that's correct. The architecture is broken down into bytes. In other words, even when you create a single BOOL, it still occupies a byte of information (8 bits). Therefore, for 4 digital inputs, you'd have a single byte (8 bits), but the inputs would only be mapped to .0, .1, .2 and .3.
You'll always have that by default. However, you can reassign the arrays to another one of your choice or use tag aliasing to give it a different name.

Hi, my problem is to change an existing backplane from a 1734-eant to an 1734-eantr without redoing every IO cards !
thanks,
Boss if I am using wifi. Trying to use rslink connect to plc . How to set ip address in the pc? Same use tcp/4? Thank you very much
Very good video....
Thank you :) do you need AOP in my laptop beforehand?

Sir I how should I have user defined name for PointIOrack1:Data[1],
I want it to different name as per my applications

In the next video can you show how to use watch window?
WTF GO A LITTLE FASTER
