West Control Solutions CALogix - Manual (Page 36)

Manual power can be selected to apply to SP1, SP2 or SP3 of a specified module and will operate when input to
the block switches from low (0) to high (1) logic state.
To return to PID control from manual power an additional block can be created within the logic program to set
manual power value to 0.
IV. Autotune
A PID module can be tuned using an output logic block.
Autotune@75%SP
(75% setpoint) or Autotune@ATSP (at setpoint) can be selected for the required PID
module.
PARK can also be selected to disable the controller outputs. In a situation where PARK is activated using a
logic function, the controller can only be taken out of PARK by changing the mode settings in CALogix-sw or via
an operator panel.
V. Event Input
Event inputs are set within the programmer functions of CALogix. If required within a program, a profile will be
held in its current position until an event input is received.
Select the module number and give the event a numerical tag that corresponds to the required event input.
For easy identification it is recommended that you give an event input the same number as he segment in the
program. For instance if the EIP segment is 4 then set the event input to number 4 in the logic, This will mean
that when the EIP segment is displayed it will appear as EIP4.
VI. Program
A program output can be used to run, stop or hold a program (profile).
Select the module and the program number along with the control mode.
