Micro 830 PLC- Master- Slave

Hello Guys,
I have two different Micro 830 PLCs, namely 2080-LC30-100QWB and other one is 24AWB. I want to make one Micro 830 as Modbus Slave and another Micro830 as Modbus Master and want to pass data from Slave to Master. Both PLCs have 2080-Serial ISOL card for communication.With Connected Components Workbench Software I could setup PLCs as Master and Slave and on Slave PLC I could do the Modbus I/O mapping to send Data over modbus. I cant figure out to receive data in Master. I using Modbus485-RTU network.

Any suggestions please.

Thanks in advance for help.

There is MSG_MODBUS Instruction in Connected workbench software, One configured properly, it will talk to all the slaves on the network and brings back the requested data.
