3.12 GSD fileThe current GSD file of the IO-Link master [ifm_0E4D�gsd] can be downloaded from our homepage www�ifm�com� With the GSD file, IO-Link sensors can be integrated directly into the system and can be parameterised� Unknown sensors, e�g� from third-party vendors, are integrated as generic IO-Link devices�

Chapter 4 of this manual contains more detailed information on the configuration of the IO-Link master and the connected sensors in a Siemens PLC�

3.12.1 Entries in the GSD fileThe GSD file shows the IO-Link master as a modular slave with max� 5 modules� Module/slot 1 is always the IO-Link module (IOLMM = IO-Link master module)� Slots 2 to 5 can be configured freely and can be used as either IO-Link port (IOL) for the connection of IO-Link sensors or as standard IO port (SIO) for the connection of simple digital sensors�

IO-Link master in the GSD fileA = entries for the IO-Link devicesB = entries for the use of ports in SIO mode

UK

IO-Link master

21

3.13 Configuration in IO-Link modeIO-Link devices can be configured as generic sensors (Generic In x byte / Generic Out x byte) according to their process data width� The entry to be selected from the GSD file has to be greater than or equal to the exact process data width of the device used�

Information about the process data width for devices from third-party vendors can be found in the documentation included with the devices�

Example configuration with sensors in IO-Link modeA = third-party sensor as generic sensor in IO-Link mode

IO-Link master

22

3.14 Configuration in SIO modeIO-Link devices can also be configured as generic sensors in SIO mode� The port has to be configured as [Generic 0 byte (SIO mode)]�

If the sensors are operated in SIO mode on slots 2 to 5, their user data are mapped into byte 0 (pin 4) of the IO-Link master (see chapter Process image)�

Example configuration with sensors in SIO modeA = third-party sensor as generic sensor in SIO mode

3.15 Parameter settingIn the configuration software, the IO-Link master is shown as modular slave with an IO-Link master module (IOLMM) at slot 1 and four IO-Link devices at slots 2 to 5� Depending on the connected sensor and the requested function of the slot, the IO-Link devices are either defined as generic IO-Link devices (e�g� sensors from third-party vendors) or as SIO (Standard Input/Output) or from the device list�

4.3.1 Hardware configurationThe hardware configuration used in the example has to be adapted by each user to his own hardware configuration� In the following description this adaptation is also done according to the hardware configuration mentioned above�

Open the hardware configurator [HW Config] and adapt the configured CPU to the current configuration� In this example a CPU 315-2EH14-0AB0 is used�Double click on the symbol of the AC2625 to open the [Properties DP slave] dialogue box� Use the button [PROFIBUS] under [Node/Master System] to open the dialogue [Properties - PROFIBUS interface AC2625]� In the register tab [Parameters] the node address for the IO-Link master is adapted (in this example address 40)�

Setting the PROFIBUS address

The input and output addresses of the IO-Link master module IOLMM (slot 1) and of the 4 IO-Link ports (slots 2 to 5) also have to be adapted to the application�

4.3.2 Configuration of the IOLMMs (IO-Link master module)Slot 1 of the modular slave contains the IO-Link master module (IOLMM)� The IOLMM is the gateway between IO-Link and PROFIBUS-DP� It prepares the IO-Link data of the IO-Link ports for further processing on PROFIBUS�Parameterisation of the IOLMMThe parameters of the IO-Link master modules (slot 1) control the communication of the entire unit including all connected devices� The parameters of slot 1 (IOLMM) have to be adapted to the application; see also Chapter 3 "Parameterisation", pages 22-24�

Make sure that the parameter [GSD parameterization] is set to active� Otherwise the following parameterisation via GSD done in the hardware configurator will be ignored!

4.3.3 Configuration of the IO-Link ports The 4 ports of the IO-Link master (slot 2 to slot 5) can be operated either in IO-Link mode or in SIO mode (see also [GSD file])�The determining factor for the function mode of the ports is their configuration�IO-Link modeIf the port is to be used in the IO-Link mode, a sensor with a process data width > 0 is selected from the hardware catalogue� IO-Link sensors from ifm [ifm … (IOL mode)] are described in the GSD file of the IO-Link master and can easily be parameterised via GSD parameters� Sensors from third-party vendors are represented as generic IO-Link devices with a maximum number of 32 byte input and/or output data�

The selected generic device has to have a process data width ≥ the process data width of the connected sensor�

For the meaning of the parameters (IO-Link, index 1, subindex x), please refer to the documentation of the respective sensor� SIO modeIf the port is to be operated in the SIO mode, select devices from the hardware catalogue with 0 byte process data [ifm … (SIO mode) or Generic 0 byte (SIO mode)]�Configuration of the IO-Link ports in this exampleAn ifm pressure sensor which is to be operated in the IO-Link mode is connected to IO-Link port 1 (slot 2)� The default entry [Generic In 8 Byte] at slot 2 is therefore replaced by the sensor ifm PI2793 (IOL-mode) from the hardware catalogue�

Parameterisation of the ifm sensor The ifm sensor is parameterised depending on the application as shown for example in the following figure: [Parameterisation via GSD]� A description of the sensor parameters can be found in the documentation of the respective sensor on www�ifm�com�

A Siemens ultrasonic sensor PXS310C M18 IO-Link (6GR6333-3KS00) which is also to be operated in the IO-Link mode is connected to IO-Link port 3 (slot 4)� The sensor is not described in the GSD file of the ifm IO-Link master and can therefore only be inserted as generic sensor (see [Configuration of the IO-Link ports])� According to the vendor Siemens it has 2 byte of process data� The default entry [Generic In 8 Byte] at slot 4 is therefore replaced by the entry [Generic In 2 Byte] from the hardware catalogue�

4.3.4 Example for the parameterisation of a generic sensorThe parameterisation of a generic sensor via the hardware configurator is only possible when the sensor provides parameters which can be set in IO-Link index 1�According to the vendor documentation, the Siemens sensor used in this project provides the following parameters in IO-Link index 1�Extract from the documentation of the used Siemens sensor

To change the [measuring range near] from 110 mm to 500 mm, the following value has to be written to index 1, subindices 7 + 8:500 mm = 0000 0001 1111 0100 = 0×01F4

– MSB subindex 7 = 0×01 = 1 – LSB subindex 8 = 0×F4 = 244

Whether (and if yes, which) parameter bytes are really written depends on the setting of the parameter [Parameterization IO-Link Index 1]� In this case, the option [Write Subindex 1 to 8] has to be selected�

While writing the parameters, all selected subindices are overwritten; this means that all subindices (in this example 1 to 8) have to contain the requested parameter values in order not to be overwritten by [0]�
