Summary
This document describes how to download a project to an OIT over an Ethernet network. Since the Maple Systems OIT product families do not currently offer this feature as an option, an Ethernet to Serial converter must be used.
Below is an Ethernet to Serial converter offered by a third party:

Example
Hardware Used:
VLINX (Ethernet to Serial Server) Model: ESP901 + Software CD
AirLink 5-Port 10/100Mbps Ethernet Switch
OITWare-200 software & an OIT3160 + cable 7431-0096
BlueLeaf Software & a BLU300 + cable 7431-0102
Windows for B&B Virtual Com port setup
Software Configuration
To configure Master HMIs to talk with a PLC over the Ethernet port:
1.
Click on Edit >> System Parameters and select the {PLC} tab.
2.
Select PLC Type: as “Modbus RTU TCP/IP”
3.
Select PLC I/F port: as “Ethernet”
4.
For the Multiple HMI box, select “Disable” if there is no slave HMIs. Select Master if any HMI is to be a slave unit and if so, select “Ethernet” for the Connect I/F.
5.
Select a unique IP Address in the Local IP Address: boxes
6.
Enter in the IP Address for the PLC in the Server IP Address: boxes. Note: Whatever the network addresses are, the numbers (Octets) in the first three boxes must match for the Local IP and the Server IP.
7.
Enter 255.255.255.0 for the Subnetwork Mask.
8.
If there is a router that will be between the HMI and the PLC, enter the router IP address in the “Default Route IP address”.
