14.2.1 SFB 0 - CTU - Up-counter
The SFB 0 can be used as Up-counter. Here you have the following characteristics:
n If the signal at the up counter input CU changes from "0" to "1" (positive edge), the
current counter value is incremented by 1 and displayed at output CV.
n When called for the first time with R="0" the counter value corresponds to the preset
value at input PV.
n When the upper limit of 32767 is reached the counter will not be incremented any fur-
ther, i.e. all rising edges at input CU are ignored.
n The counter is reset to zero if reset input R has signal state "1".
n Output Q has signal state "1" if CV ≥ PV.
n When it is necessary that the instances of this SFB are initialized after a restart, then
the respective instances must be initialized in OB 100 with R = 1.
Parameter Declaration Data type Memory block Description
CU INPUT BOOL I, Q, M, D, L,
constant
Count input
R INPUT BOOL I, Q, M, D, L,
constant
Reset input. R takes precedence over
CU.
PV INPUT INT I, Q, M, D, L,
constant
Preset value
Q OUTPUT BOOL I, Q, M, D, L Status of the counter
CV OUTPUT INT I, Q, M, D, L Current count
Count input:
This counter is incremented by 1 when a rising edge (with respect to the most recent SFB
call) is applied to input CU.
Reset input:
The counter is reset to 0 when input R is set to "1", irrespective of the status of input CU.
Preset value:
This value is the comparison value for the current counter value. Output Q indicates
whether the current count is greater than or equal to the preset value PV.
