(5) Simultaneous temperature rise AT
PID constants and the simultaneous temperature rise parameter are calculated. The waveform upon execution is
the same as that for the auto tuning function.
For details on the auto tuning function, refer to the following.
Page 159, Section 8.3.7
(a) How to execute the simultaneous temperature rise AT function
1.
Set "Method selection" to "Param write" of the control mode to be used.
"CC IE Field Configuration" windowSelect the temperature control module from "List of
stations"[CC IE Field Configuration][Online][Parameter Processing of Slave Station]
2.
Set "1: AT for simultaneous temperature rise" under "CH Simultaneous temperature rise AT
mode selection".
3.
Turn off and on CH Auto tuning instruction (RY20 to RY23).
4.
When the operating status is changed from stop to run, simultaneous temperature rise AT starts.
(b) Operation with the simultaneous temperature rise AT function
After the procedure described on Page 202, Section 8.3.17 (5) (a) is executed, the temperature control
module operates as following.
CH Auto tuning status (RX20 to RX23) is turned on. Then normal auto tuning is performed and the simultaneous temperature
1
rise parameter is calculated.
The calculated value is stored in the remote buffer memory when the simultaneous temperature rise parameter is normally
calculated. In addition, CH AT simultaneous temperature rise parameter calculation completion (b0, b4, b8, b12 of RWr3) is
2
turned 1 (ON). After auto tuning is completed, CH Auto tuning status (RX20 to RX23) is turned off and the module is shifted to
the PID control.
