FUN 86
TPCTL
z R4006: The setting point of large power output detection for SSR or heating circuit opened, or heating band
obsolete. The unit is in % and the setting range falls in 80～100(%); system default is 90(%).
z R4007: The setting time to detect the continuing duration of large power output while SSR or heating circuit
opened, or heating band obsolete. The unit is in second and the setting range falls in 60～65535
(seconds); system default is 600 (seconds).
z R4008: The setting point of highest temperature warning for SSR, or heating circuit short detection. The
unit is in 0.1 degree and the setting range falls in 100～65535; system default is 3500 ( Unit in 0.1
°).
z R4012: Each bit of R4012 to tell the need of PID temperature control.
Bit0=1 means that 1
st
point needs PID temperature control.
Bit1=1 means that 2
nd
point needs PID temperature control.

Bit15=1 means that 16
th
point needs PID temperature control.
(The default of R4012 is FFFFH)
z R4013: Each bit of R4013 to tell the need of PID temperature control.
Bit0=1 means that 17
th
point needs PID temperature control.
Bit1=1 means that 18
th
point needs PID temperature control.

Bit15=1 means that 32
th
point needs PID temperature control.
(The default of R4013 is FFFFH)
z While execution control “EN”=1 and the corresponding bit of PID control of that point is ON (corresponding
bit of R4012 or R4013 must be 1), the FUN86 instruction will perform the PID operation and respond to the
calculation with the output signal.
z While execution control “EN”=1 and the corresponding bit of PID control of that point is OFF (corresponding
bit of R4012 or R4013 must be 0), the FUN86 will not perform the PID operation and the output of that point
will be OFF.
z The ladder program may control the corresponding bit of R4012 and R4013 to tell the FUN86 to perform or
not to perform the PID control, and it needs only one FUN86 instruction.
