2.2
Functions
2.2.1
Switching cycle counter
The function records the number of switching cycles of the output and thus the switching
cycles of a connected actuator, such as those of solenoid valves. When the specified
number of switching cycles is reached, the "Limit value warning" maintenance interrupt is
triggered, provided it is configured and enabled. When replacing the actuator, you can reset
the switching cycle counter from the user program.
When replacing modules, you have the option of pre-initializing the switching cycle counter
from the user program.
Typical areas of application:
●Recording the number of switching cycles of the connected devices, e.g. solenoid valves
or load contactors
●Predictive maintenance
Advantages
●You configure this function instead of programming.
●"Monitoring" of each individual channel is possible. You can select which outputs are
"monitored".
●You can adapt the plant configuration flexibly and individually.
●Easy to service and maintain. You can enable and disable the switching cycle counter via
the user program.
●Increase in plant availability. You can schedule actuator replacement in advance for the
next maintenance cycle.
Requirement
Firmware version as of V1.1.0 of the module.
Configuration
You configure the switching cycle counter with the following parameters:
●Switching cycle counter enabled/disabled
●Trigger maintenance interrupt when the limit is reached
●Set limit for maintenance interrupt

Digital output module DQ 16x24VDC/0.5A HF (6ES7522-1BH01-0AB0)
14 Manual, 06/2018, A5E35683409-AC
How it works
The module counts the switching cycles by evaluating the rising edges of an output signal. If
the module detects a rising edge, the switching cycle counter (24-bit) for the respective
channel is incremented. After an overflow of the switching cycle counter, it starts again with
0.
If you activate the "Maintenance switching cycles" parameter, the "Limit warning" of the
maintenance interrupt is triggered when the limit is exceeded. Alternatively, activate the
maintenance interrupt in the parameter data sets starting at DS 64.
The current counter states are stored on the module cyclically (approx. every 20 seconds)
and retentively. The switching cycle counters are reset each time the module is restarted
(power off/on).
You activate the function with the "Switching cycle counter" parameter or in the parameter
data sets starting at DS 64.
You can read the current counter states with data set DS 129. Data set DS 129 contains the
counter status for each channel in UDINT format.
You can read the limits for each channel in UDINT format with data set DS 130.
Data set DS 131 enables you to overwrite the current counter value for each switching cycle
counter.
You can set a limit for each switching cycle counter with the "Switching cycle limit" parameter
or with data set DS 131.

16 Manual, 06/2018, A5E35683409-AC
Note
When the 24 V supply voltage is switched on at each channel, there is a "1" signal at the
module outputs for approx. 50
μs.
Tip: Using the potential jumpers
If you want to supply both load groups with the same potential (non-isolated), use the
potential jumpers supplied with the front connector. This helps you to avoid having to
terminate two wires to one terminal.
Proceed as follows:
1. Connect the 24 V DC supply voltage to terminals 19 and 20.
2. Insert the potential jumpers between terminals
–9 and 29 (L+)
–10 and 30 (M)
–19 and 39 (L+)
–20 and 40 (M)
3. Insert the jumpers between terminals 29 and 39, as well as 30 and 40.
4. Use the terminals 19 and 20 to distribute the potential to the next module.
Figure 3-2 Using the potential jumpers
Note
Ensure that the maximum current load of 8 A per potential jumper is not exceeded.

Description of parameters
No supply voltage
Enabling of the diagnostics, for lacking or insufficient supply voltage L+.
Short circuit to ground
Enabling of the diagnostics if a short-circuit of the actuator supply (CHx) to ground occurs.
Maintenance switching cycles
You use this parameter to enable the maintenance interrupt "Limit value warning" when the
switching cycle limit is violated.
You configure the limit with the parameter "Switching cycle limit" for each channel CHx.
Switching cycle counter
Channel-by-channel enable of switching cycle counter (Page 13).
Wire break
Enabling of the diagnostics if the line to the actuator is broken.
Reaction to CPU STOP
Determines the reaction of the output when the CPU goes into the STOP state or when the
connection to the CPU is interrupted.
Switching cycle limit
Defines the limit channel-by-channel. If this value is exceeded, the "Limit value warning"
maintenance interrupt is signaled.
Enter an integer value between 0 and 16777214. Refer to the data sheet of the connected
actuator. We recommend that you do not enter this maximum value, but instead set it to 80%
or 90%, for example, so that you have enough time to replace the actuator as a preventive
measure.
