Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be connected
to an enterprise network or the internet if and to the extent such a connection is necessary
and only when appropriate security measures (e.g. firewalls and/or network segmentation)
are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure to
cyber threats.

Product overview
2.2 Functions
Digital output module DQ 8x230VAC/2A ST Triac (6ES7522-5FF00-0AB0)
10 Equipment Manual, 12/2021, A5E03485733-AE
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 V2.2.0 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 alarm

2.2 Functions
Digital output module DQ 8x230VAC/2A ST Triac (6ES7522-5FF00-0AB0)
Equipment Manual, 12/2021, A5E03485733-AE 11
Principle of operation
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 alarm in the parameter data records 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.

Parameters/address space

4.1 Parameters
DQ 8x230VAC/2A ST parameters
When you assign the module parameters in STEP 7, you use various parameters to specify the
module properties. The following table lists the configurable parameters. The effective range
of the configurable parameters depends on the type of configuration. The following
configurations are possible:
•Central operation with a S7-1500 CPU
•Distributed operation on PROFINET IO in an ET 200MP system
•Distributed operation on PROFIBUS DP in an ET 200MP system
For parameter assignment in the user program, the parameters are transferred to the module
using the WRREC instruction (parameter reassignment in RUN) and data records; see chapter
Parameter assignment and structure of the parameter data records (Page 26).

14 Equipment Manual, 12/2021, A5E03485733-AE
4.2 Declaration of parameters
Switching cycle counter maintenance
You use this parameter to enable the maintenance alarm "Limit value warning" when the
switching cycle counter limit is violated.
You configure the limit with the parameter "Switching cycle limit" for each channel CHx.
Reaction to CPU STOP
Determines the reaction of the output to the CPU going into STOP state or when the
connection to the CPU is interrupted.
Switching cycle counter
Channel-by-channel enable of switching cycle counter (Page 10).
Switching cycle counter 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. Recommendation: Instead of entering the maximum value, set the value, e.g., to
80% or 90% of the maximum value. You then have enough time to preventatively change the
actuator.

The module can be configured differently in STEP 7; see following table. Depending on the
configuration, additional/different addresses are assigned in the process image output/input.
Configuration options of DQ 8x230VAC/2A ST
You can configure the module with STEP 7 (TIA Portal) or with a GSD file.
When you configure the module by means of the GSD file, the configurations are available
under different short designations/module names.

Value status (Quality Information, QI)
The value status is always activated for the DQ 8x230VAC/2A ST MSO module.
An additional bit is assigned to each channel for the value status. The bit for the value status
indicates if the output value specified by the user program is actually pending at the module
terminal (0 = value is incorrect).
Address space for configuration as 8-channel DQ 8x230VAC/2A ST
The following figure shows the assignment of the address space for the configuration as a
8-channel module with value status. You can freely assign the start address for the module.
The addresses of the channels are derived from the start address.
The letters "a to d" are printed on the module; "QB a", for example, stands for module start
address output byte a.

16 Equipment Manual, 12/2021, A5E03485733-AE
Address space for configuration as 1 x 8-channel DQ 8x230VAC/2A ST MSO
For the configuration as a 1 x 8-channel module (module-internal Shared Output, MSO),
channels 0 to 7 of the module are copied to multiple submodules. Channels 0 to 7 are then
available with identical values in various submodules. These submodules can be assigned to
up to four IO controllers when the module is used in a shared device:
•The IO controller to which submodule 1 is assigned has write access to outputs 0 to 7.
•The IO controllers to which submodule 2, 3, or 4 is assigned have read access to outputs 0
to 7.
The number of usable IO controllers depends on the interface module used. Please observe
the information in the manual for the particular interface module.
Value status (Quality Information, QI)
The meaning of the value status depends on the submodule involved.
For the first submodule (=basic submodule), the value status 0 indicates that the value is
incorrect or that the IO controller of the basic submodule is in STOP state.
For the 2nd to 4th submodule (=MSO submodule), the value status 0 indicates that the value
is incorrect or one of the following errors has occurred:
•The basic submodule is not yet configured (not ready).
•The connection between the IO controller and the basic submodule has been interrupted.
•The IO controller of the basic submodule is in STOP or POWER OFF state.
