Delta RMC151 - Manual (Page 582)

RMC70/150 and RMCTools User Manual
Use the AutomationDirect Hx-ECOM100 modules to communicate with the RMC75E or
RMC150E. Refer to the AutomationDirect HX-ECOM-M manual for instructions on how to
use it.
Setting up the Hx-ECOM100
For each RMC that the PLC will communicate with, use NetEdit to add a Peer-to-Peer
configuration to the Hx-ECOM100 for Modbus/TCP. Specify the Modbus/TCP protocol and
enter the IP Address of the RMC. The Port number must be 502. The value in the Unit ID
is not important.
Using the to the Hx-ECOM100
Use the Hx-ECOM100 as a Network Client (master), as described in the MODBUS
TCP/IP for H0/H2/H4–ECOM100 chapter, Network Client (master) Operation
section of the Hx-ECOM100 manual.
Calculating RMC Register Addresses
Use the Register Maps to find the Modbus/TCP addresses of the desired registers in the
RMC75E. Then convert the addresses to octal as described in the Hx-ECOM100 manual.
The AutomationDirect PLCs cannot access all the registers in the RMC. Therefore, use the
Indirect Data Map to map the desired registers to one location that the PLC can read. This
also makes the communications more efficient.
Communicating with the RMC75S
For the DL05/06 series, set up the D0-DCM module as a Modbus/RTU master. For the
250-1 or 260, configure the second CPU port as a Modbus/RTU master.
Calculating RMC75S Register Addresses
Use the RMC70 Register Map to find the Modbus/TCP addresses of the desired registers in
the RMC75S. Then convert the addresses to octal as described in the Hx-ECOM100
manual.
The AutomationDirect PLCs cannot access all the registers in the RMC75S. Therefore, use
the Indirect Data Map to map the desired registers to one location that the PLC can read.
This also makes the communications more efficient.
6.11.4. Using GE PLCs with the RMC
The RMC75E and RMC150E can communicate with the GE FANUC RX3i, RX7i, and 90-30 PLCs
via the Modbus/TCP Ethernet protocol. The RX3i requires the IC695ETM001 Ethernet module.
Example Programs
Delta offers a sample RX3i PLC program to help you quickly set up the communications
between your PLC and the RMC. See the downloads section of Delta's website at
www.deltamotion.com.
Using the GE Ethernet Communications
The GE Fanuc manual “TCP/IP Ethernet Communications for PACSystems”, number GFK-
2224D, provides very good detail on how to use the IC695ETM001 Ethernet module. The
RX3i must be used as a Modbus/TCP client, which is described in Chapter 8 of the
manual. Use the example PLC program on Delta's website as a starting point for your
application.
