Hello,

I’m using Allen Bradley Micro850 , 2080-LC50-24QWB.

I wrote a program using Connected Component Workbench which reads certain indications and controlling contactors.

My customer would like to connect that PLC to a PC by an Ethernet cable RJ45 and read those input registers and write those output registers into his application that he had built.

He would like to know the commands in order to read or write the data and the TCP/IP data structures and frames.

i have been searching this information in the data sheets and have found none.

i hope you could help me or at least instruct me becasue that’s really urgent.

thanks in advance.
