Product overview 2.1 Properties Properties The module has the following technical properties: ● 16 digital inputs; electrically isolated in groups of 16 ● Rated input voltage 24 V DC ● Configurable input delay: 0.
Product overview 2.1 Properties Other components The following component must be ordered separately: Front connectors, including potential jumpers and cable ties You can find more information on accessories in the S7-1500 Automation System (http://support.automation.siemens.com/WW/view/en/59191792) system manual and the ET 200MP Distributed I/O System (http://support.automation.siemens.com/WW/view/en/59193214) system manual.
3 Wiring This section contains the block diagram of the module and outlines various connection options. For more information on front connector wiring and creating cable shields, for example, refer to the "Wiring" section in the S7-1500 Automation System (http://support.automation.siemens.com/WW/view/en/59191792) and ET 200MP distributed I/O system (http://support.automation.siemens.com/WW/view/en/59193214) system manuals.
Wiring Wiring and block diagrams The figure below shows you how to connect the module and channel addressing (input byte a to input byte b). ① Backplane bus interface Figure 3-1 Block diagram and terminal assignment 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.
Wiring Tip: Using the potential jumpers Use the potential jumpers supplied with the front connector if you want to distribute the 24V DC supply voltage to a neighboring module. 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 19 and 39 (L+) and between terminals 20 and 40 (M). 3.
4 Parameters/address space 4.1 Parameters DI 16x24VDC HF 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.
Parameters/address space 4.2 Address space Parameters Range of values Default Parameter assignment in RUN Scope with configuration software, e.g.
Parameters/address space 4.2 Address space Value status (Quality Information, QI) The value status is always activated for the following module names: ● DI 16x24VDC HF QI, ● DI 16x24VDC HF QI S ● DI 16x24VDC HF MSI An additional bit is assigned to each channel for the value status. The value status bit indicates if the read in digital value is valid. (0 = value is incorrect).
Parameters/address space 4.2 Address space Address space for configuration as 2 x 8-channel DI 16x24VDC HF QI S For the configuration as a 2 x 8-channel module, the channels of the module are divided into multiple submodules. The submodules can be assigned to different IO controllers when the module is used in a shared device. The number of usable submodules is dependent on the interface module used. Observe the information in the manual for the particular interface module.
Parameters/address space 4.2 Address space Address space for configuration as 1 x 16-channel DI 16x24VDC HF MSI The channels 0 to 15 of the module are copied in up to four submodules with configuration 1 x 16-channel module (Module-internal shared input, MSI). Channels 0 to 15 are then available with identical input values in different submodules. These submodules can be assigned to up to four IO controllers when the module is used in a shared device.
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.
5 Interrupts/diagnostics alarms 5.1 Status and error displays LED displays The following figure shows the LED displays (status and error displays) of DI 16x24VDC HF.
Interrupts/diagnostics alarms 5.1 Status and error displays Meaning of the LED displays The following tables explain the meaning of the status and error displays. Remedial measures for diagnostic reports can be found in chapter Diagnostics alarms (Page 24). RUN and ERROR LED Table 5- 1 Status and error displays RUN and ERROR LED Meaning RUN ERROR Off Off Voltage missing or too low at backplane bus Flashes Off The module starts and flashes until the valid parameter assignment is set.
Interrupts/diagnostics alarms 5.1 Status and error displays CHx LED Table 5- 3 CHx status display LED CHx Meaning Remedy 0 = Status of the input signal --- 1 = Status of the input signal --- Diagnostics: Wire break Check the wiring. When using simple switches, deactivate diagnostics or connect a resistor (25 kΩ … 45 kΩ) to the encoder contacts. Supply voltage L+ too low or missing Check supply voltage L+.

Parameter data records B.1 B 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 a GSD file is used to configure a module, dependencies can arise when "assigning the parameters". There are no dependencies for this module. You can assign the individual parameters in any combination.
Parameter data records B.1 Parameter assignment and structure of the parameter data records Assignment of data record and channel For the configuration as a 1 x 16-channel module, the parameters are located in data records 0 to 15 and are assigned as follows: ● Data record 0 for channel 0 ● Data record 1 for channel 1 ● … ● Data record 14 for channel 14 ● Data record 15 for channel 15 For the configuration as a 2 x 8-channel module, the module has 2 submodules with eight channels each.
Parameter data records B.1 Parameter assignment and structure of the parameter data records Data record structure The example in the following figure shows the structure of data record 0 for channel 0. The structure of channels 1 to 15 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".
