CH1 Feed forward control forced start READY flag
When the deviation (E) enters the disturbance judgment position and the temperature process value (PV) is judged to be
stable enough (It may take about 60 seconds to judge the stability.) while the action conditions of the disturbance suppression
function have been satisfied, this flag turns ON. For details on the disturbance suppression function, refer to the following:
Page 117 Disturbance Suppression Function
• 0: OFF
• 1: ON
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory area name
CH Feed forward control forced start READY flag
CH Feed forward control forced start READY flag (in the Q compatible mode)
■Turning OFF 'CH1 Feed forward control forced start READY flag' (Un\G418)
At the following timing, 'CH1 Feed forward control forced start READY flag' (Un\G418) turns OFF.
• At power-ON
• During the disturbance suppression
• When the action conditions of the disturbance suppression function have not been satisfied
• When the temperature process value (PV) has responded in a reverse direction of the disturbance judgment position and
goes outside the disturbance judgment width
• When the setting of 'CH1 Feed forward value tuning selection' (Un\G561) is changed from No automatic setting (0) to
Automatic setting (1) (The tuning is executed on the disturbance after the change.)
CH1 Sensor two-point correction offset latch completion
When the latch of the sensor two-point correction offset value is completed, Latch completed (1) is stored in this area.
When 'CH1 Sensor two-point correction offset latch request' (Un\G566) is set to No request (0), No request (0) is stored in this
area.
For details on the sensor two-point correction function, refer to the following:

CH Sensor two-point correction offset latch completion
CH Sensor two-point correction offset latch completion (in the Q compatible
mode)
CH1 Sensor two-point correction gain latch completion
When the latch of the sensor two-point correction gain value is completed, Latch completed (1) is stored in this area.
When 'CH1 Sensor two-point correction gain latch request' (Un\G567) is set to No request (0), No request (0) is stored in this
area.
For details on the sensor two-point correction function, refer to the following:
