time, the channel should be set in the state of temperature control and heating); M8 ~ M11 elements map
directly to Bit0 ~ Bit3 of #999. By setting M8 ~ M11 elements, you can also directly control the opening
and closing of each channel self-tuning.
* 8. #1008 ~ #1011: heating/cooling operation selection. When the "position proportional PID" mode is
selected, the MV value of temperature control output is the change of PID output value.
* 9. #1016 ~ #1019: manually output Settings. Set the duty cycle of the constant output of each channel,
the setting range is: 0 ~ 1000 (unit is 0.1%), the default value is 0.
* 10.# 1149
～
# 1152: Set the rate of change to limit the increase. # 1157
～
# 1160: Set the change
rate to limit the decline. Range 0 ~ Range range, when set to 0, it means there is no limit to temperature
rise / cooling, the unit is
℃
/ min.
* 11. # 1165
～
# 1168: Selection of temperature control object characteristics. When the slow heating
object is selected, the temperature control output period, integration time, and derivative time are in
seconds; when the rapid heating object is selected, the temperature control output period, integration
time, and derivative time are in hundred milliseconds;
* 12. #1205 ~ #1208: manual/automatic no disturbance switch Settings. When the manual/automatic
non-disturbance switch setting is effective, the module will switch from manual mode to automatic mode
or from automatic mode to manual mode, and the temperature control output MV value will switch
smoothly to the next output state.
