6.1 Introduction
A set of variable definitions is provided to enable the host to monitor and sometimes alter, the
behaviour of the equipment. These are known as machine variables.
Machine variables are divided into the following three categories.
Equipment Constants: Allow the host to modify certain aspects of the equipment’s
behaviour. See section 5.5 for a discussion on the use of EC’s.
Status Variables: As the name suggests, these variables track continuous system
status values. The host can interrogate the equipment at any time
and can programme the equipment to transmit values on a
regular schedule. The host cannot change these values.
See section 5.2 for a discussion on data collection methods.
Discrete Data Variables: Are similar to Status Variables except that their values are valid
only when specific events occur. The host should not interrogate
these values, but should include them in reports linked to
collection events.
See section 5.2 for a discussion in on data collection methods.
Process Attributes: These variables are used to request name and value information
about the currently loaded printer product.
The machine variables are listed by category in the following sections.
