(6) CH Operation monitor (RX11 to RX14)
This signal monitors the condition of CH1 to CH4 of the temperature control module (operating or stopped). The
signal turns on during the operation and turns off when the operation is stopped.
(a) In the temperature input mode
When CH Operation request flag (RY11 to RY14) is turned on, the signal turns on at the timing when first
conversion is completed and the temperature process value is stored in the remote register area.
(b) In the standard control mode, heating-cooling control mode, or mix control mode
When CH Operation request flag (RY11 to RY14) is turned on, the signal turns on at the timing when the shift
to the control mode is completed.
For the timing of turning on and off CH Operation request flag (RY11 to RY14) and the signal, refer to the
following.
• CH Operation request flag (RY11 to RY14) ( Page 296, Appendix 1.2 (4))
• CH Stop request flag (RY18 to RY1B) ( Page 298, Appendix 1.2 (7))
(7) Back-up of the set value completion flag (RX15)
Turning on Set value backup instruction (RY15) starts the writing of the remote buffer memory data to the non-
volatile memory. After the data writing is completed, this signal turns on. Turning off Set value backup instruction
(RY15) also turns off the signal.
