The Command and Parameter areas of the main screen can operate in either of the following two modes:
Read-back Mode
In this mode, the Command and Parameter areas will be continually read from the RMC. This mode is necessary to monitor the commands given from another source (such as the PLC) and also to determine the parameters stored on the RMC. The Command area field values are displayed in red.
Note: Because the Command and Parameter fields are constantly being updated, it is possible to have changes you are making be overwritten by a field update. To avoid this, RMCWin will not update the fields in the area of the selected cell. For example, if a parameter on axis 2 is currently selected, then RMCWin will not overwrite the parameters for axis two until the currently selected cell moves out of axis 2's parameters.
Write Mode
In this mode, the Command and Parameter areas are never automatically updated. You can freely change values without them being overwritten by automatic updates. The Command area field values are displayed in yellow.
To switch between Read-back and Write modes, use one of the following methods:
On the Tools menu, click Toggle to readback/write mode.
Press CTRL+T from the main screen.
Double-click the status bar pane that says either Read or Write.
