If the proportional-integral (P-I) control method is selected, control commands will be sent
through the
Output variable (heating)
communication object. This will be a 1-bit object or a
1-byte object, depending on the setting of the
Output type
parameter.
For proper operation of the P-I control method, the
Cycle time
,
Proportional band
, and
Integral
time
parameters need to be defined. The latter two can be defined explicitly, or (more conve-
niently) one of the available predefined options may be selected from the
Control parameters
list.
See
on page 34 for a detailed description of all control parameters
involved.
