Connecting via Modbus TCP (Ethernet)
With standard Ethernet cables connect the controller(s) and the Silver Series EM OIT to an Ethernet
switch or connect the controller directly to the OIT.
Determining or Setting the OIT’s IP Address
If you connect the OIT to an Ethernet network in order to download programs or communicate with
controllers via Ethernet, you must ensure the OIT has a unique IP address and you will need to know
that address in order to communicate from your PC with the OIT.
To read or set the OIT’s IP address:
• Connect a USB mouse to the OIT, if desired.
• Apply power to the OIT.
• Once the OIT is powered up, move the mouse to the lower right corner of the OIT screen.
• On the menu bar click the setting button (the one with the gear icon).
• Enter the password. (By default this is 111111.)
