2.3.4 Channel PIDs
Each Channel has a set of PID constants and variables. Each channel implements a PID control algorithm
that determines its Heat and Cool outputs. The PID variables can be logged for documentation and tuning
purposes.
2.3.5 Channel Primitives
The channel primitives are the algorithms that control each output device such as fans, compressors,
heaters, etc. The Synergy Controller supports multiple instances of the same primitive. For example in the
thermal shock application there are two hot chambers and one cold chamber and thus uses two Heat output
primitives. Each primitive output is displayed in the Events/Digital Outputs folder.
2.3.6 Channel Setpoints
Each channel has a setpoint. The setpoint can be a steady-state value, a profile generated setpoint or a
remote setpoint from a computer or PLC.
2.3.7 User Programmable Alarm System
The user programmable alarm system can be programmed for one or more alarms using any input or
channel value. These alarms can be used for various purposes including chamber protection, unit-under-test
protection, or chamber control. See the user programmable alarm Section 6.14
for details.
2.3.8 Logging System
The logging system is used to capture test results and chamber performance data as well as alarm
conditions. The logging system can acquire data from any controller input, channel or PID output. See the
logging section 6.11
of the manual for detailed setup instructions.
2.3.9 Analog Retransmit Outputs
The Analog Retransmit Outputs can be used to retransmit process or control variables as a proportional
voltage to chart recorders or proportional control valves. There are two retransmit outputs. See Analog
Retransmits in the Special Function Section 6.4
for more details,
