Maple Systems OIT Family - Manual (Page 83)

Delete
The DELETE key is used, when editing a read/write PLC register monitor, to perform a
destructive backspace at the cursors current position in the screen.
Requirements: The DELETE key is not required if you have a CLEAR key, since the
CLEAR key clears the entire entry and lets you start over.
Control, Edit & Numeric Key Coils
The OIT Control Key feature provides the ability to configure any of the non-function
keys of the OIT so that they can set/reset a PLC coil that is assigned to it. This feature is
useful in applications in which the PLC ladder logic must know when certain keys are
pressed, (i.e. the [ENTER] key). It is also useful in OIT models that do not have a
mappable keyboard (ex. OIT3200) that the programmer wishes to convert an action key
such as the [LastMsg] key to a momentary function key.
Each of the OIT’s control, edit and numeric keys can be programmed to:
• only perform normal OIT action
• only set/clear a PLC coil
NOTE: Pressing the key sets the coil; releasing the key clears the coil.
• perform normal OIT action and set/clear a PLC coil
• do nothing (disabled).
When a new OITware-200 project is started, all of the control, edit and numeric keys default to
OIT Action mode (they only perform their normal OIT action). If you want one or all of the keys
to function in a different mode, you need to use the OIT Control Key Editor.
To configure the control, edit and numeric key coils:
1. From the configuration menu, choose Keyboard Settings, then choose Control Key
Editor. The OIT Control Key Editor dialog box appears with each available control,
edit and numeric key listed.
NOTE: Some of the control keys listed cannot be configured using the OIT Control Key feature.
Which keys can be configured is based upon the model OIT selected.
