Table 8-3 Parameters for operating mode: Counter or frequency measurement
Operating mode Parameter
Frequency measurement (operating mode only)
Counter
● High counting limit (1 to 4 294 967 295*)
● Comparison value (1 to 4 294 967 295*)
● Reaction to violation of the high counting limit:
Continue counting / Stop counting
● Edge selection:
On rising edge / On falling edge / On rising and falling edge
● Set output DQ: Between comparison value and low limit / Between
comparison value and high limit
● DQ channel (for comparison event - requires free DQ channel):
Use by user program / Channel <n>
● Hardware interrupt (for comparison event):
Lock / Comparison event for DQ occurred
● Hardware gate channel (requires free DI channel): None / Deactivated;
Channel <n>
You can find additional information in the glossary.
* Note on use with PCS 7; The parameter permits values up to 32 bits without sign. This means the
maximum value is FFFF FFFF
H
(4 294 967 295). In PCS 7, the representation is limited to 2
31
-1 by the
DINT data type.
Procedure
1. Open HW Config.
2. In the index list, double-click the "DIQ" slot.
The "Properties - DIQ..." dialog box opens.
3. Make the system-specific settings.
Standard behavior (non-activated channel)
A channel that is not activated always behaves like a "digital input" without sensor supply.
