ASCII over Ethernet

4 posts in this topic

I have a 1756-L71 controller with a 1756-ENBT/A Ethernet module. How do I have a program

send ASCII to a commercial power supply to turn on/off set values query status ect.

Thanks

John

You will need to get a different Ethernet Module to open a socket...

What is the make and model of the power supply?

Cheers,

Hal

The old 1756-ENBT doesn't have the ability to open a generic TCP socket and send generic data through it.   You will need either an old 1756-EWEB, or a modern 1756-EN2T or 1756-EN3T module to do that.

The Rockwell "application guide" for generic TCP messaging is publication ENET-AT002.   Search with that publication number or the keywords "socket programming TCP" at the RA literature website:   https://www.rockwellautomation.com/global/literature-library/overview.page
