Modbus I/Os Read/Write from Micro850

Hello,

I'm using Allen Bradley Micro850 - 2080-LC50-24QWB PLC. I downloaded a program to that PLC by CCW.

My customer wants to build an application (like a GUI) on a PC which ables to read and write the I/Os. Therefore he needs me to send him the registers of the I/Os that i have used in the program.

So I would like to know the register for every tag or I/O. Where can i get that information from?

For example, I would like to read: _IO_EM_DI_00. How could i know what this tag's Modbus register is?

thanks in advance.
 
The tags don't have a Modbus register because they aren't Modbus. They have to be mapped.

Under the Micro850 Tab > Controller > Modbus Mapping<pre>
Variable Name Data Type Address Addresses Used
_IO_EM_DI_00 BOOL 000001 000001</pre>
