5.24 OT, operating hours counter
The function block is used to record the operating hours of independent
events or states. The status of the operating hours counter is also retained
when in a de-energized state. As soon as the enable coil of the function block
is active, the easy800 counts the hours in minutes, although the display only
shows hours.
easy800 device allows the use of up to 4 hours-run counters.
Contacts and Coils
Example of an operating hours counter:
Figure 162:Wiring the function block coils
The enable coil of the function block is connected here directly to the device
inputs. A marker activates the reset coil.
Figure 163:Wiring of the function block contact
The message of the function block was wired to a device output.
Parametric programming of the function block inputs/outputs
When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure on the left. Enter the function block settings here.
The display contains the following elements:
Input
The >I1 block input is used to specify the upper setpoint value in hours.
