Communications Specification 47
• Proportional band
• High process alarm
• Low process alarm
• Deviation band alarm
• Heat/cool spread
• Alarm deadband
Ranges for all input parameters are determined as follows:
• For thermocouple and RTD inputs, the high and low ranges are fixed
at the values shown in the previous table.
• For pulse and linear inputs, the high and low ranges are determined
by the values entered for input scaling, as shown in the graph below.
Output Type (4)
This parameter defines the output type of a given output pin.
• Default: Heat outputs default to manual control, enabled, reverse
action, time proportioning. Cool outputs default to disabled, direct
action, time proportioning.
• Range: A 1-byte value determined as shown in the tables below.
