3 Wiring This section contains the block diagram of the module and outlines various wiring options. You will find information on wiring the front connector, establishing a cable shield, etc in the system manual S7-1500/ET 200MP (http://support.automation.siemens.com/WW/view/en/59191792) in section Wiring. Wiring and block diagram The figure below shows how to wire the module and assign channel addresses (input byte a up to input byte d).
Wiring Resistor circuitry of the encoders To detect a wire break, it is necessary that enough quiescent current is flowing even when the encoder contacts are open. Connect a resistor of 25 kΩ to 45 kΩ with 0.25 W to the encoder contacts for this reason. Figure 3-2 Resistor circuitry of the encoders 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.
Parameters/address space 4.1 4 Parameter DI 32x24VDC HF parameters When you assign the module parameters in STEP 7, you use various parameters to specify the module properties. The parameters that can be set depend on whether you use the module in standard mode or in counter mode. You will find the parameters in section Parameters DI mode (Page 16) or section Parameters of the Counting mode (Page 18). The effective range of the configurable parameters depends on the type of configuration.
Parameters/address space 4.1 Parameter 4.1.1 Parameters DI mode Parameters of the DI 32x24VDC HF in the DI mode In the following table, you will find the parameters in the "DI mode". These parameters apply to channels 0 to 31. Table 4- 1 Settable parameters and their defaults in the DI mode Parameter Range of values Default setting Parameter reassignment in RUN Range of effectiveness with configuration software, e.g.
Parameters/address space 4.1 Parameter 4.1.2 Explanation of the parameters of the DI mode No supply voltage L+ Enabling of the diagnostics, with missing or too little supply voltage L+. Wire break Enabling diagnostics if the line to the encoder is interrupted. Input delay This parameter can be used to suppress signal disruptions. Changes to the signal are only detected if they are constantly pending longer than the set input delay time.
Parameters/address space 4.1 Parameter 4.1.3 Parameters of the Counting mode Parameters of the DI 32x24VDC HF Count in the Counting mode If you want to use the module for counting, you need to set the module parameters as DI 32x24VDC HF Count. For channels 0 and channel 1, the following parameter settings are then possible. For channels 2 to 31, the parameter settings apply as with the DI 32x24VDC HF, , see section Parameters DI mode (Page 16).
Parameters/address space 4.1 Parameter Parameter Range of values Default setting Parameter Range of effectiveness with conreassignment figuration software, e.g. STEP 7 in RUN Integrated in the GSD file hardware catalog PROFIBUS DP as of STEP 7, V13 SP1 with HSP 0118 or GSD file PROFINET IO Start value 0 ...
Parameters/address space 4.1 Parameter 4.1.4 Explanation of the parameters of the Counting mode Missing supply voltage L+ Enabling of the diagnostics, with missing or too little supply voltage L+. Wire break Enabling diagnostics if the line to the encoder is interrupted. Input delay This parameter can be used to suppress signal disruptions. Changes to the signal are only detected if they are constantly pending longer than the set input delay time.
Parameters/address space 4.1 Parameter Comparison value With this parameter you specify the count value at which the digital output DQ (STS_DQ bit of the feedback interface) switches due to the selected comparison event. Start value With this parameter, you specify the value at which counting begins and is continued if defined events occur. The following condition must be met: Low counting limit < = start value < = high counting limit.
Parameters/address space 4.2 Address space 4.2 Address space 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 of the inputs. The letters "a to d" are printed onto the module. "EB a" for example, stands for module start address input byte a. Configuration options of DI 32x24VDC HF You can configure the module with STEP 7 (TIA Portal) or with a GSD file.
Parameters/address space 4.2 Address space 4.2.1 Address space DI mode Address space for configuration as 32-channel DI 32x24VDC HF QI The following figure shows the assignment of the address space for the configuration as a 32-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.
Parameters/address space 4.2 Address space Address space for configuration as 4 x 8-channel DI 32x24VDC HF S QI For the configuration as a 4 x 8-channel module, the channels of the module are divided into four submodules. The submodules can be assigned to different IO controllers when the module is used in a shared device. The number of I/O controllers depends on the interface module being used. Observe the information in the manual for the particular interface module.
Parameters/address space 4.2 Address space Value status (Quality Information, QI) The meaning of the value status depends on the submodule on which it occurs. For the first submodule (=basic submodule), the value status 0 indicates that the value is incorrect. For the 2nd to 4th submodule (=MSI submodule), the value status 0 indicates that the value is incorrect or the basic submodule has not yet been configured (not ready).
Parameters/address space 4.2 Address space The following figure shows the assignment of the address space with submodules 3 and 4 and the value status. Figure 4-4 Address space for configuration as 1 x 32-channel DI 32x24VDC HF MSI with value status Reference You will find information on the module-internal shared input/shared output (MSI/MSO) in the function manual PROFINET with STEP 7 V13 (http://support.automation.siemens.
Parameters/address space 4.2 Address space 4.2.2 Address space Counting mode Address space for configuration as 1 x 32-channel DI 32x24VDC Count The address space of channel 0 and channel 1 used for counting consists of the control and feedback interface. The Count function is controlled directly via the two interfaces. With suitable parameter assignment, a hardware interrupt is triggered.
Parameters/address space 4.2 Address space Figure 4-6 Assignment of the address space of the control interface of the DI 32x24VDC Count (bytes 8 to 15) Feedback interface The following figure shows the address assignment of the module in the process image input. The feedback interface for the counters (channels 0 and 1) begins at input byte x+8. Via the feedback interface, the user program receives current counted values and status information from the module.

Parameters/address space 4.2 Address space 4.2.3 Examples of counting In this section, you will find examples of the behavior of the counter and how you can specify this behavior. You specify the properties of the counter in the parameter assignment. Behavior when a counting limit is exceeded - Stop counting The following section describes the effects of the parameter "Behavior when a counting limit is exceeded = Stop counting".
Parameters/address space 4.2 Address space Behavior when a counting limit is exceeded - Continue counting The following section describes the effects of the parameter "Behavior when a counting limit is exceeded = Continue counting". To control the counter, the bits of the control byte of the control interface are used, see section Address space Counting mode (Page 27), subsection Control interface. Counting begins at the current counted value (the SW-GATE is set in the control byte).
Parameters/address space 4.2 Address space Set output DQ - behavior of the STS_DQ bit The following section shows the behavior of the STS_DQ bit with the parameter assignment "Set output DQ = between comparison value and high counting limit". The STS_DQ bit is set to 1 when the comparison value < = counted value <= high counting limit is reached. As an option, a hardware interrupt can be enabled in the parameter assignment. This is generated with the parameter rising edge of the STS_DQ bit.
Parameters/address space 4.2 Address space The following section shows the behavior of the STS_DQ bit with the parameter assignment "Set output DQ = between low counting limit and comparison value". The STS_DQ bit is set to 1 when the low counting limit < = counted value < = comparison value is reached. As an option, a hardware interrupt can be enabled in the parameter assignment. This is generated with the parameter rising edge of the STS_DQ bit.
Parameters/address space 4.2 Address space Gate control The opening and closing of the software gate (SW-GATE) defines the time window in which the count signals are acquired. The software gate is controlled by the user program. Reference You can find additional information on the counting functionality in the function manual S7-1500, ET 200MP, ET 200SP counting, measuring and position detection (http://support.automation.siemens.com/WW/view/en/59709820).

B Parameter data records B.1 Parameter assignment and structure of the parameter data records The data records of the module have an identical structure, regardless of whether you configure the module with PROFIBUS DP or PROFINET IO. Dependencies for configuration with GSD file When configuring the module with a GSD file, remember that the settings of some parameters are dependent on each other. The parameters are only checked for plausibility by the module after the transfer to the module.
Parameter data records B.2 Structure of the parameter data records DI mode Operation of the module behind a PROFIBUS DP interface module If the module is operated behind a PROFIBUS DP interface module, the parameter data records 0 and 1 are not read back. You get the diagnostics data records 0 and 1 for the read back parameter data records 0 and 1. You can find more information in the Interrupts section of the PROFIBUS DP interface module device manual on the Internet (http://support.automation.siemens.
Parameter data records B.2 Structure of the parameter data records DI mode Structure of a data record in the DI mode The example in the following figure shows the structure of data record 0 for channel 0. The structure of channels 1 to 31 is identical. The values in byte 0 and byte 1 are fixed and may not be changed. Enable a parameter by setting the corresponding bit to "1".
Parameter data records B.3 Structure of the parameter data records Counting mode B.
Parameter data records B.3 Structure of the parameter data records Counting mode Structure of data record 0 of the Counting mode The example in the figure below shows the structure of data record 0 for channel 0. The structure of channel 1 is identical, the values are located in data record 1. The values in byte 0 and byte 1 are fixed and may not be changed. Enable a parameter by setting the corresponding bit to "1".
Parameter data records B.3 Structure of the parameter data records Counting mode Figure B-3 Structure of data record 0: Bytes 5 to 17 Keep in mind that the counter is stopped and reset to the start value when you change count parameters. Changing the parameters "Diagnostics" and "Hardware interrupts" does not have an effect on the counter.
