• Enter the password by clicking only the keys on the Virtual keyboard. If you click the caption
bar or other part of the Virtual keyboard window, your keystrokes are not entered in the System
Settings dialog.
• You can tell the password key strokes are being entered if you hear the key chirp from the OIT
and see stars (******) appearing in the password field.
• If you cannot see the Password field, arrange the Virtual Keyboard and System Settings
dialog then make sure the cursor is in the Password field.
• If you are entering the password on the Virtual Keyboard but stars aren’t appearing in the
Password field, make sure the Password field has focus. If you do not see the text insertion
cursor ( | ) in the Password field, it does not have focus. Click in the Password field to give it

Chapter 3: Communications
Basics
The Silver Series OIT can communicate with Watlow controllers via Modbus TCP or Modbus RTU.
This section defines terms you will encounter and provides information about Modbus communications
that will help you create a user interface with the Silver Series OIT for equipment and machines that
include Watlow controllers.
About Gateways, Controllers and PLCs
The Silver Series OIT can communicate with a variety of devices. Because many of these devices are
Programmable Logic Controllers (PLCs), EasyBuilder5000 refers to devices in many places generically
as “PLCs”. Don’t let this confuse you. When you are setting up the OIT to communicate with a Watlow
product, from the OIT’s point of view the controller is a PLC.
This addendum refers to configuring the Silver Series OIT to communicate with “controllers”, but the
instructions apply equally to limit controllers and gateways such as the EZ-ZONE
®
RUI Gateway.
