MOD 30ML Display Guide
Application Examples
• TEMPERAT – configured as a floating point input with an initial value of 0. Then
an external connection is made to the Temperature PID Block setpoint.
• RECIPE – a count input that represents the recipe number. This input requires an
associated format that will allow display of actual recipe name (added to the State
Tables), on Line 6.
Using the UP or DOWN arrow key the operator selects the appropriate recipe by name.
The order in which they appear is defined by the order of the Display Tags in the Display
List (Display Interface Block). Each name represents a state value (in this case 0 - 2) of
the input named RECIPE. The setpoint values for the temperature and pressure PID loops
are defined for each case. As a case is selected the values defined for temperature and
pressure are sent to the appropriate block.
If, in the DIF block, any one of the PID block displays are defined to appear first after
a power fail recovery (Power Up Display field), then the initial value for setpoint will
be defined by the PID block initial values. If the Recipe Display block is defined to
come up first after a power fail recovery then the values for the setpoints and the timer
will be determined by the selected recipe data. Define the ‘Power Up Display” to
cause the right startup values according to your needs.
