Auto refresh setting

Set the buffer memory for each channel in the Q64TCN where auto refresh is performed.

• Write data error code • CH alert definition

•CH temperature process value (PV) • CH alert set value 1

•CH manipulated value (MV) • CH alert set value 2

•CH set value (SV) setting • CH alert set value 3

•CH proportional band (P) setting • CH alert set value 4

•CH integral time (I) setting • CT heater disconnection alert setting

•CH derivative time (D) setting • CT heater current process value

•CH loop disconnection detection judgment time • CH manipulated value (0-4000/0-12000/0-16000)

•CH transistor output flag • CH temperature rise judgment flag

Values stored in the buffer memory in the Q64TCN where the auto refresh setting is configured are

automatically read when the CPU module executes END instruction.

Monitor/test

Monitor/test the buffer memory and I/O signals of the Q64TCN.

Also the auto tuning function can be executed.
