General Overview
This Setup Guide shows you how to configure the MVI56E-MNETC module and
establish communication with a Modbus TCP/IP device (a Quantum processor
with a NOE Ethernet adapter, for this example).
The MVI56E-MNETC Ethernet application port will be configured as a Modbus
TCP/IP (MNET) Client device. The NOE Ethernet adapter will operate as a
Modbus TCP/IP Server device, passing data to the Quantum processor. The
MVI56E-MNETC will be configured to send two MNET Client commands to the
Modbus TCP/IP Server device:
Write 10 words (Modbus Function 16 - Preset [Write] Multiple Registers
Read 10 words (Modbus Function 3 -Read Holding Registers
When you finish the steps in this Setup Guide, you will have enough information
to set up your own application.
