This document describes setting up a connection that allows Red lion device to essentially act as a Modbus passthru
Products
Red Lion Controls CR1000 Human Machine Interface (HMI), CR3000 HMI, Data Acquisition (DA10, DA30), Data Station Plus, FlexEdge™ (DA50A, DA70A), G3 HMI, G3 Kadet HMI, Graphite® Controller, Graphite HMI, Modular Controller, and Productivity Station™
Required Software:
Crimson 3.0, Crimson 3.1 & Crimson 3.2
Use Case:
Third Party HMI which talks Modbus TCP/IP but cannot do Modbus RTU via 485 and you are looking to read/write data to/from three third party Modbus RTU Slave devices via RS 485
or
Third Party HMI which talks Modbus RTU but cannot do Modbus TCP/IP and you are looking to read/write data to/from three third party Modbus TCP/IP Slave devices.
Notes:
Consider these two scenarios:
You have an HMI which talks Modbus TCP/IP but cannot do Modbus RTU via 485 and you are looking to read/write data to/from three Modbus RTU Slave devices via RS 485. Modbus gateway driver allows the red lion to be configured as multiple Modbus TCP/IP slaves with different drop numbers so that HMI can read/write data and then you eventually map the data to the Modbus RTU Slave devices via RS 485 port.

You have an HMI which talks Modbus RTU but cannot do Modbus TCP/IP and you are looking to read/write data to/from three Modbus TCP/IP Slave devices Modbus gateway driver allows the red lion to be configured as multiple Modbus RTU slaves with different drop numbers so that HMI can read/write data and then you eventually map the data to the Modbus TCP/IP Slave devices.
I have used the first scenario as example in the database attached.
