<p>PURPOSE:To accurately grasp both maximum and minimum cycle times by actually executing a sequence program to replace said cycle times and displaying these replaced values. CONSTITUTION:The time Tn is read out of a timer and at the same time the previous time T0 is read out of a memory 30 for calculation of the actual cycle time Tc=Tn-T0. When the measure cycle time Tc is larger than the maximum value Tmax of the stored cycle time, the time Tc is substituted for the value Tmax for acquisition of the maximum value. When the time Tc is smaller than the value Tmax, the time Tc is composed with the stored minimum time Tmin. If the time Tc is smaller than the value Tmin, the time Tc is replaced with the value Tmin for acuisition of the minimum time. Then the memory time T0 is replaced with the time Tn. Both maximum and minimum values are displayed on a display device 43.</p> |
