Enhanced Features
 

Recipe Screens

Recipe screens allow the operator to download or upload preset values into PLC registers. These preset values are configured when programming the OIT, and can also be modified at any time by the OIT operator. Recipe screens allow the OIT operator to configure and start a batch process. Each recipe screen can include up to 20 preset values. Each recipe screen also includes:

Initiator - A signed character in the bottom right corner of the recipe screen that the OIT operator must change from 'N' to 'Y' to download the recipe to the PLC.
Gate coil - A PLC relay coil that the OIT uses to signal the PLC that the recipe has been downloaded and the batch process is ready to start.

On the MicroOIT Series, you can also configure any screen-dependent function key to upload or download a recipe. The PLC/controller has the ability to send an upload or download command to the OIT using the message request register.

Memory Storage for Motion Controllers

The MicroOIT Series has the ability to store data for later retrieval from a PLC or motion controller. This is particularly useful in applications in which the controller has no internal memory that is non-volatile. For example, suppose that a controller is used that requires initial operational settings whenever the controller is powered. These settings may be stored in the OIT to be downloaded into the controller after power-up. This feature saves time and ensures that the correct settings are always sent to the controller. The MicroOIT stores data internally using the recipe screen feature. With recipes, data can be uploaded from the controller and stored in the OIT's non-volatile flash memory. When needed, data can be sent back to the controller by pressing a key on the OIT or by sending a download command from the controller.

Multiple Language Support

This feature can be used to support control system applications in which multiple languages are required. For example, if you are creating a control system that may be sold to companies with offices around the world, you may not know which part of the world the system will be eventually shipped to at the time of manufacture. Without this feature, you would be forced to create multiple projects for the OIT, each in a different language. Then you would have to wait until the destination was known before configuring the OIT.

The multi-language feature allows you to "split" the 500 screens available in the OIT into 2, 5 or 10 separate groups or languages. Once configured, you create the screens that pertain to that language using the copy and paste function and then changing the language. When the control system is shipped to its final destination, the OIT operator places the OIT into the setup mode and selects which language is to be displayed.
