■One-shot output for command pulse period
This function block performs one-shot output for command pulse period according to the operation from the faceplate or the
input from the input variables (FWD_SET, STOP_SET, REV_SET).
• When the setting is performed with the faceplate or the value of the input variable (FWD_SET) is changed from FALSE to
TRUE, this function block outputs a command pulse signal (TRUE) from the output variable FWD by the time period set
with the command pulse period (DOT).
• When the setting is performed with the faceplate or the value of the input variable (STOP_SET) is changed from FALSE to
TRUE, this function block outputs a command pulse signal (TRUE) from the output variable STOP_ by the time period set
with the command pulse period (DOT).
• When the setting is performed with the faceplate or the value of the input variable (REV_SET) is changed from FALSE to
TRUE, this function block outputs a command pulse signal (TRUE) from the output variable REV by the time period set with
the command pulse period (DOT).

■Time-out detection/time-out reset
• Time-out detection
A time-out (TOA) of an alarm (ALM) will occur if TRUE or FALSE is not input from the status answer input (FWD_ST) for a
time longer than the time set with the time-out timer (TOT) after a command pulse signal (TRUE) is output from the output
variable FWD or STOP_.
A time-out (TOA) of an alarm (ALM) will occur if TRUE or FALSE is not input from the status answer input (REV_ST) for a time
longer than the time set with the time-out timer (TOT) after a command pulse signal (TRUE) is output from the output variable
REV or STOP_.
Condition
Time to a status answer signal input  Time set with the time-out timer (TOT)
Time to a status answer signal input < Time set with the time-out timer (TOT)
• Time-out reset
A time-out (TOA) of an alarm (ALM) is reset (FALSE) by either of the following operations.
A command pulse signal is output from the output variable (FWD, STOP_, REV) by the operation with the faceplate or the
input from the input variable (FWD_SET, STOP_SET, REV_SET).
TRUE is input to the input variable (TO_RST).
■SIM/OVER answer back time delay signal
In SIMULATION mode or OVERRIDE mode, this function block creates a status answer signal after a command signal output
in the CPU module.
The lag time of this status answer signal is set with the simulation answer time (SIMT).
