Hi, How do I address safety inputs and outputs from the safety PLC to my main PLC program? Usually I'd use a PILZ relay to drop out coil&main power to contactors and then control contactors from my PLC, however someone else has designed this machine so there is a safety PLC which I have to turn the contactors on through the safety PLC. So the inputs from the safety PLC and outputs from the safety PLC need to be read + written to from my main ladder logic....is this possible? Also - using a variable in my main PLC program in the safety program, is this possible? I want to use my 'Safety OK' + a variable from my PLC to turn on a Relay (which is connected to a safe output)

Edit - managed to do it. Omron tutorial isn't relevant any more.

Hi, Is it possible with NB Designer to send a project file to someone and they can plug in using a USB Flash drive + the screen will take that file and update itself? I have done this on previous HMI's but never tried with Omron NB range.

Siemens I could do this.... however on Sysmac Studio i can't seem to do this... I just want to be able to set the first bit of an integer...or even a word! Is there a way of doing this without using Unions etc?
-
What i was trying to do wasn't special. In Siemens I can address a BIT inside an INT without having to make a union.
-
Just seems a finnicky way of doing it, such a basic function is rather long winded. Unions are the way to go I think! Thanks anyway!

Thanks. I used a Union in the end and it works rather well. Sysmac has some quirks which I still need to get used to! If anyone is reading this, just go to data types > union. See pic.
