When the setting is performed with the faceplate or the value of the input variable (RUN) is changed from FALSE to TRUE, this function block stores the

current value + 1 (counter value) in the process variable (PV) in the unit set with the counter multiplying factor (MULT).

When the process variable (PV) reaches the estimated value (PSV), TRUE will be output from the output variable PRE_COMP. (Preset value comparison

in the block diagram)

When the process variable (PV) reaches the setting value (SV), TRUE will be output from the output variable COMP_. (Setting value comparison in the

block diagram)

When the process variable (PV) reaches the counter high limit (RH), the counter stops.

(2)

When the setting is performed with the faceplate or the value of the input variable (STP) is changed from FALSE to TRUE, measuring the process variable

(PV) will be stopped.

(3)

When the setting is performed with the faceplate or the value of the input variable (RST_) is changed from FALSE to TRUE, the process variable (PV) will

be set to the counter low limit (RL) value, and the counter stops.

(4)

When the setting is performed with the faceplate or the value of the input variable (RS_START) is changed from FALSE to TRUE, the process variable

(PV) will be set to the counter low limit (RL) value, and the counter starts.
