Counter instructions

If reset is set, the current_value (CV) will be reset. If up_clock is set, the value 1 is added to the

current_value. This procedure is repeated for each rising edge detected at up_clock until the

current value is greater than/equal to the set_value. Then output_up is set. The procedure is not

conducted, if reset and/or set is/are set.

If set is set (status = TRUE), the set_value (PV = preset value) will be loaded in the current_value

(CV). If down_clock is set, the value 1 is subtracted from set_value at each clock. This procedure

is repeated at each clock until the current_value is smaller than/equal to zero. Then,

signal_output is set. The procedure will not be conducted, if reset and/or set is/are set or if CU

and CV are set at the same time. In the latter case, counting will be downwards.

When programming with structured text, enter the following:

copy_name(CU:= up_clock, CD:= down_clock, RESET:= reset, LOAD:= set, PV:=

QU=> output_up, QD=> output_down, CV=> current_value);
