@collinsd70 how do you create a UDT and a chain of structure text or protocol etc. for example serial it's easy you just open de port and shout "masdkkjdhfhjdfjsdfjdsf" and it goes out. Ethernet to what level does it goes into Rslogix?
@Walks the solution to your application might be with a product that a partner of mine found, it is from the brand RTA or Real Time Automation, Inc. https://www.rtautomation.com/
We work in a project to integrate an scale weight sending serial data to AB PLC's. in the same project we integrate (and this is off-topic) another cool product from the brand Mapple Systems to show Tags in a TV.
first contribution after many reads, hope someone finds it useful. Regards.
