PLC Serial Port to Vending machine DEX protocol?


Thread Starter

Anibal Hernandez


Can you provide me with help for connecting a PLC Serial Port to a Vending machine DEX protocol?

I need to monitor several parameters in 4 Vending machines here in San Juan, Puerto Rico and load them into the PLC. The machines are manufactured by Royal and Dixie-Narco.

I also have the option for using Visual Basic v6.0 instead of the PLC ladder logic language.

Do you know how to do this?

Thanks for your help.

Omron kave a Protocol Macro function that enables the user to write their own code to communicate with any serial device. This software, CX-Protocol, is available for use with many of their PLCs.
