Counter - Controlling
The controlling of the appropriate counter is made from the user program
by the SFB COUNT (SFB 47). The SFB is to be called with the
corresponding instance DB. Here the parameters of the SFB are stored.
With the SFB COUNT (SFB 47) you have following functional options:
•
Start/Stop the counter via software gate SW_GATE
•
Enable/control output DO
•
Read the status bit
•
Read the actual count and latch value
•
Request to read/write internal counter registers

LADDR INPUT WORD 0.0 300h This parameter is not evaluated. Always
the internal I/O periphery is addressed.
CHANNEL INPUT INT 2.0 0 Channel number
SW_GATE INPUT BOOL 4.0 FALSE Enables the Software gate
CTRL_DO INPUT BOOL 4.1 FALSE Enables the output
False: Standard Digital Output
SET_DO INPUT BOOL 4.2 FALSE Parameter is not evaluated
JOB_REQ INPUT BOOL 4.3 FALSE Initiates the job (edge 0-1)
JOB_ID INPUT WORD 6.0 0 Job ID
JOB_VAL INPUT DINT 8.0 0 Value for write jobs
STS_GATE OUTPUT BOOL 12.0 FALSE Status of the internal gate
STS_STRT OUTPUT BOOL 12.1 FALSE Status of the hardware gate (is only
refreshed if "HW gate" is activated in
hardware configuration before)

STS_DO OUTPUT BOOL 12.3 FALSE Status of the output
STS_C_DN OUTPUT BOOL 12.4 FALSE Status of the down-count
Always indicates the last direction of
count. After the first SFB call STS_C_DN
is set FALSE.
STS_C_UP OUTPUT BOOL 12.5 FALSE Status of the up-count
Always indicates the last direction of
count. After the first SFB call STS_C_UP
is set TRUE.
