Global R parameters

Global R parameters are arithmetic parameters, which exist in the control itself, and can be read
or written to by all channels.
You use global R parameters to exchange information between channels, or if global settings are
to be evaluated for all channels.
These values are retained after the controller is switched off.
Comments

These comments can be edited. You have the option of either individually deleting these
comments, or using the delete function.
These comments are retained after the control is switched off.
