What is an Operator Interface Terminal ( OIT )?
Maple Systems Alphanumeric OITs are powerful, affordable operator interface terminals.
Our units offer best-in-class features including:
- 2 and 4-line LCD and VFD Displays
- 16 and 24-key keypads
- unique user-definable keypads
- slide-in legends.
With the ability to communicate with more than 100 brands of PLCs such as Emerson, GE, Koyo, Mitsubishi, Schneider, and many more; motion controllers, temperature controllers, and embedded microcontrollers, you can easily create the perfect operator interface terminal for your application.
All our OITs operate in temperature extremes ranging from -10°C up to 65°C and meets strict Class 1, Division 2 UL requirements. Made with a rugged aluminum enclosure in the USA, our LCD and VFD OITs are ideal for harsh environments.
What is OITware?
Maple Systems OITware-200 comes with powerful features to make configuring your OIT products more intuitive:- Multi-language support allows you to configure an OIT with 2, 5, or 10 different languages
- Recipe uploads and downloads can be triggered by either the OIT or the controller
- Remote variable storage function provides greater storage capacity
- Your Operator Interface Terminal, or OIT, can be configured as a Modbus slave device
- Expanded support for Allen-Bradley MicroLogix Controllers, including the L data file
- Added support for CTC motion controllers, Yaskawa-Magnetek controllers, and Control Microsystems controllers
Can I connect multiple OITs to one PLC?
Yes, the OITs connect together in a daisychain fashion. One of the OITs is designated as the ‘master’ while the other OITs are defined as ‘slaves’. The master OIT is directly connected to the PLC communications port. Each slave OIT then communicates through the master OIT to get data from the PLC. No additional communications modules are required which provides an effective and inexpensive way to connect multiple OITs to a single PLC.How can I upload or download to an OIT?
To upload or download to a Maple Systems Operator Interface Terminal (OIT), use our configuration cable (part number 7431-0096). This requires a serial connection between the PC and OIT so you can use a USB-to-RS232 adapter on the PC if it doesn’t have a 9-pin serial port. To put the OIT into upload/download mode, press and hold the key in bottom-right corner of the OIT while it is powering up. You should see the word “Initializing” in the screen followed by “Setup Password:.” Press the Enter key. If the OIT requires a password to enter the Setup screen, it will say “Incorrect Password” and reboot. You will need to go back to the Setup Password screen and enter the correct password. The next screen will say “Dn/Upload Mode? YES.” Press the Enter key again. The next screen will say “Computer Comm Mode. Computer must log-on.” The OIT is now ready for uploading or downloading a project.
What is the “master” or “backdoor” password on an OIT?
The “master” or “backdoor” password on an OIT is 12089.
What is the difference between Human Machine Interface (HMI), and Operator Interface Terminal (OIT)?
All OITs are HMIs, but not all HMIs are OITs. OIT (Operator Interface Terminal) usually means a dedicated terminal with graphics and/or text that provides data/control of a local (rather than remote) piece of equipment or a process by a person acting as an operator of said equipment. HMIs can also mean the same thing, but they can also be something that provides remote monitoring and/or operational control of an entire system.
What is the difference between VFD and LCD OITs?
Great for normal lighting conditions, our Backlit LCD (Liquid Crystal Display) Operator Interface Terminals, or OITs, are rugged and reliable. They are operable in temperature extremes ranging from -10°C up to 65°C. Features include 2 or 4-line Displays, 6 to 24-key keypads, a custom slide-in legends and are Class I, Division 2.
VFD (Vacuum Fluorescent Displays) Operator Interface Terminals, or OITs, are useful in situations where a crisp high-contrast display is desired. The light-emitting display makes it more readily viewable in low-light environments. They are operable in temperature extremes ranging from -10°C up to 65°C. Features include 2 or 4-line Displays, 6 to 24-key keypads, a custom slide-in legends, and are Class I, Division 2.
Do you have models that meet the Class I, Division 2 requirement?
Yes we do. Our HTML5 Web HMIs, HMI + PLCs series, AEx Industrial Panel PCs and Embedded Box PCs, select Standard HMIs, and OIT series meet strict Class I, Division 2 requirements. These products are used in industries including: oil and gas, mining, painting, chemical processing, pharmaceutical, food processing, and more.
