9.2 Tuning once
Autotuning procedure is executed only once at next REVO RT restart. If for any reason the procedure doesn’t
work, it will be be executed at next restart.
The Tuning Once function is enabled for each Loop, with the "Tune" parameter in the configurator for each
Loop, or via serial port by setting "3" on the parameters: :
• P85 Add 2085 for Loop 1,
• P111 Add 2111 for Loop 2,
• P137 Add 2137 for Loop 3.
9.3 Self tuning
The Adaptive Tuning function is used to automatically optimize the
PID when environmental conditions change.
The Self Tune function is enabled for each Loop with the “Tune”
parameter in the configurator for each Loop, o via serial by setting
“1” on the following parameters:
• P85 Add 2085 for Loop 1
• P111 Add 2111 for Loop 2
• P137 Add 2137 for Loop 3
the controller analyzes the process oscillations and optimizes
the PID parameters to obtain a stable process, if the regulation
oscillates outside a threshold established by the parameters:
• P101 = threshold value for Loop 1
• P127 = threshold value for Loop 2
• P153 = threshold value for Loop 3
When in operation, the values at the Modbus address are as follows:
• 1216 = value 1 for Loop 1
• 1217 = value 1 for Loop 2
• 1218 = value 1 for Loop 3
On the configurator, during the Pre Tune operation, the “AT”
LED on the configurator will be on.
