Output Network Variables
Default name Default type Description
CV SNVT_lec_cont_f The control variable network

SP_Out SNVT_temp_f
(changeable)
The setpoint output network

tab for more information.
Auto_Man_Out SNVT_switch The auto/manual output network
variable. If this network variable is
set to On, it indicates that this PID
Controller is functioning in Auto. If
this network variable is set to Off,
it indicates that this PID controller
is operating in Manual. See the
