2.7.24 SETPOINT GENERATOR 1
The Setpoint Generator 1 (SPG 1) module provides a continuous output signal that is derived from
one of three sources which are the setpoint track value (STV), the remote setpoint (RSP), or the lo-
cal setpoint push buttons. The output priority is STV, RSP, and setpoint push buttons. The input
variable parameter values also affect the output, as determined by the setpoint selection made.
The two tables that follow list the input variables and the parameters. As shown in the third table,
two logical output signals, L128 and L132, indicate which source is supplying the continuous out-
put signal at C137. An illustration of the SPG 1 module follows the tables.
