• When the target setpoint tracking is ON

When the program operation of the last segment ends, the operation is set to local
mode (constant SP) as shown below. At this point, the final SP of the last segment is
used continuously as the SP in local mode. The “local SP” can be specified
beforehand. However, if the target setpoint tracking is ON, the PV tracks to the final
SP of the final segment regardless of the local SP.

After the last segment ends, the local
SP is set to the final SP of the last
segment regardless of the "local SP"
specified beforehand, and the operation
continues under fixed-point control.

• When the target setpoint tracking is OFF

When the program operation of the last segment ends, the operation is set to local
mode (constant SP) as shown below (next page). At this point, the output is
controlled using the preset “local SP,” and PV event and time event are turned OFF.

Reset-Mode End
When the segment set to reset-mode end is terminated, program control enters the stop
(reset) status, and the operation of each control loop is stopped.

Note

When creating the program pattern, data is created so that the segment set to [Local] or

[Reset] is the last segment of program control.
