(13)CH Simultaneous temperature rise status (RX24 to RX27)
The execution state of the simultaneous temperature rise can be monitored with this signal.
• OFF: Simultaneous temperature rise not in process
• ON: Simultaneous temperature rise in process
During control with the simultaneous temperature rise function, this signal turns to Simultaneous temperature rise
in process (ON).
The following figure shows the timing when the signal turns to Simultaneous temperature rise not in process
(OFF). (In the figure, CH1 and CH2 are set to group 1. (Page 357, Appendix 3 (59))

The signal does not turn to Simultaneous temperature rise not in process (OFF) at the completion of the
temperature rise. As in the figure above, the temperature is raised to a certain point with the simultaneous
temperature rise function, and the signal remains Simultaneous temperature rise in process (ON) for that interval.
After that the temperature is raised with the PID constants of each channel, and the signal turns to Simultaneous
temperature rise not in process (OFF).
For details on the simultaneous temperature rise function, refer to the following.
