■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).
Input signal from the faceplate or
the input pin (rising edge detection)
Command pulse signal
from the output pin
SIM/OVER answer back signal
■Disable alarm detection
Set whether to detect the alarm (ALM) and alarm 2 (ALM2) or not in the SV variation rate & high/low limiter and time-out
detection.
Item
Disable alarm detection by setting tag data
Disable alarm detection by loop stop processing
■Output processing at occurrence of SEA
The function block sets both OPEN and CLOSE of command signal output to FALSE when a sensor error (SEA) has occurred
in M+P_IN, a tag access FB.
■Loop stop processing
When the stop alarm (SPA) of the alarm (ALM) or the tag stop (TSTP) of the monitor output buffer (DOM) is TRUE, this
function block performs the following processing.
• Both OPEN and CLOSE output FALSE.
• The control mode is automatically changed to MANUAL.
• The trip (TRIPA) and time-out (TOA) are not reset.
• When DSVLA, SVHA, or SVLA of the alarm 2 (ALM2) has occurred, the DSVLA, SVHA, or SVLA is reset.
• No alarm is detected in the SV variation rate & high/low limiter.

Disable alarm detection processing
If the following bits in the disable alarm detection (INH) and disable alarm
detection 2 (INH2) are TRUE, TOA, TRIPA, DSVLA, SVHA, and SVLA of the
alarm (ALM) and the alarm 2 (ALM2) will not be detected.
