Limits (LOOP_RAMP_DT)

  • Hi Hi Lim – This field displays the maximum value of the PV in engineering units before the high high limit active bit (HI_HI_ACT) is set. Click this field to enter a new limit.

  • Hi Lim – This field displays the maximum value of the PV in engineering units before the high limit active bit (HI_ACT) is set. Click this field to enter a new limit.

  • Dev Hi Lim – This field displays the maximum positive deviation of the PV from SP in engineering units before the high deviation limit active bit (DV_HI_ACT) is set. Click this field to enter a new limit.

  • Dev Lo Lim – This field displays the maximum negative deviation of the PV from SP in engineering units before the low deviation limit active bit (DV_LO_ACT) is set. Click this field to enter a new limit.

  • Lo Lim – This field displays the minimum value of the PV in engineering units before the low limit active bit (LO_ACT) is set. Click this field to enter a new limit.

  • Lo Lo Lim – This field displays the minimum value of the PV in engineering units before the low low limit active bit (LO_LO_ACT) is set. Click this field to enter a new limit.

  • Out Hi Lim – This field displays the maximum value of the output in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the output scale in engineering units.

  • Out Lo Lim – This field displays the minimum value of the output in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the output scale in engineering units.

  • ARW Hi Lim – This field displays the high limit of Anti-Reset Windup. When the output is beyond ARW_HI_LIM and the integral action is returning toward the limit, the applied RESET time is reduced by a factor of 16. The valid input range is a value between OUT_HI_LIM and OUT_LO_LIM.

  • ARW Lo Lim – This field displays the low limit of Anti-Reset Windup. When the output is beyond ARW_LO_LIM and the integral action is returning toward the limit, the applied RESET time is reduced by a factor of 16. The valid input range is a value between OUT_HI_LIM and OUT_LO_LIM.

  • SP Hi Lim – This field displays the maximum value of the SP in engineering units. Click this field to enter a new limit. The valid input range for this value is -10 to 110 % of the PV Scale in engineering units.

  • SP Lo Lim – This field displays the minimum value of the SP in engineering units. Click this field to enter a new limit. The valid input range for this value is –10 to 110 % of the PV Scale in engineering units.
