Schematic
The following schematic shows the "Counters" logic modules:
Figure 4-95
Note
The time between the events to be counted depends on
• The input delay
• The device cycle time.
Note
The actual value remains the same
• During parameterization or failure of the supply voltage
• If there are simultaneous input signals at input + and input -.
Note
The output is always 0 if a reset is pending.
Settings
Table 4- 88 Counter settings
Counters 1 to 6 Description
Input + Increments actual value by 1
Activation by any signal (any sockets, e.g. device inputs, control bits from the communication bus, etc.)
Input - Decrements the actual value by 1.
Activation by any signal (any sockets, e.g. device inputs, control bits from the communication bus, etc.)
Reset Reset the actual value to 0 (count value and output).
Activation by any signal (any sockets, e.g. device inputs, control bits from the communication bus, etc.)
Limit Value that can be reached when counting and at which the counter issues an output signal.
Range: 0 to 65535 (default: 0)
