2 Hardware Installation

Switch Setting

Node Address

000 (Default setting)

Use the network configuration stored in the flash. The default network configuration values are:

• IP address = 192.168.60.101

• Subnet mask = 255.255.255.0

• IP gateway = 0.0.0.0

After completing the hardware installation, see chapter 3 Configuring the IO-Link Master with STEP 7 to set the network address using the web interface.

001-254

This is the last three digits in the IP address. This uses the first three numbers from the configured static address, which defaults to 192.168.60.xxx.

Note: If software is used to change the IP address to another range before setting

the rotary switches, the IO-Link Master uses that IP address range. For example, if the IO-Link Master is set to 10.0.0.250 and the first rotary switch is set to 2, the IP address would be 10.0.0.200.

255-887

Reserved.

888

Reset to factory defaults. If the IO-Link Master is set to 888 and the IP address is changed using other methods, the IP address is returned to the default IP address if the IO-Link Master is rebooted or power cycled.

889-997

Use the network configuration values stored in the flash (reserved).

2 Hardware Installation

Use the following procedures to install the IO-Link Master hardware:



Setting the Rotary Switch (IP67 Model): see chapter 2.1



Connecting to the Network: see chapter 2.2



Connecting the Power: see chapter 2.3



Mounting the IO-Link Master: see chapter 2.3 Note: The MD 248i-12-8K/L4-2R2K must be installed in a suitable fire, electrical, mechanical enclosure.

2.1 Setting the Rotary Switch (IP67 Model) You can use the rotary switches under the configuration window on the IO-Link Master to set the lower

3-digits (8 bits) of the static IP address. Optionally, you can leave the rotary switch set to the default and use the embedded web interface to set the network address.

If the rotary switches are set to a non-default position, the upper 9-digits (24 bits) of the IP address are then taken from the static network address. The switches only take effect during startup, but the current position is always shown on Help | SUPPORT page.

Using the rotary switches to set the IP address may be useful in the following situations:

 A permanent method to assign IP addresses while setting machines for a special application

where a PC or laptop is not available.

 A temporary method to assign IP addresses to several IO-Link Masters so that they do not have

duplicate addresses to make setting the IP addresses using software easier. After the web page to change the IP address, reset the rotary switches back to 000.

 An emergency method to return the IO-Link Master back to factory defaults, so that software can

be used to program the appropriate IP address, and then return the switches back to 000.

Note: If you set the network address using the rotary switches, the rotary switch setting overrides the network

settings in the web interface when the IO-Link Master is initially powered on or after cycling the power.

3.7 Configuring IO-Link Ports The IO-Link Master gateway has two categories of IO modules:



IO-Link Port Modules: see chapter 3.7.1



Port Status Modules: see chapter 3.7.2

IO modules are used to configure IO-Link ports and exchange PDI and PDO data with various IO-Link devices and digital I/O devices. The following image shows available modules of the IO-Link Master.

Figure 13: IO-Link Master I/O modules

3.7.1 IO-Link Port Modules An IO-Link port can be configured as one of the following:

 IO-Link Mode  SIO Digital In Mode

 SIO Digital Out Mode. IO-Link Port modules are used to configure the mode of an IO-Link port. All the IO-Link modules start with the IO-Link (that is: IO-Link In, IO-Link Out and IO-Link In/Out)

configure the corresponding IO-Link port as IO-Link Mode. An SIO Digital In module configures the IOLink port as SIO Digital In Mode. Similarly, an SIO Digital Out module configures the port as SIO Digital Out Mode.

 An IO-Link module can be input only, output only or both. In addition, there are different modules

with various IO data sizes (1 to 32 bytes). For example, the IO-Link In/Out 4 bytes module is for an IO-Link device that supports up to 4-byte PDI data and 4-byte PDO data. If you do not find an exact matching IO size, select the next size (larger). For instance, use IO-Link in 16-bytes module for an IO-Link device that has 10-byte PDI data. The unused PDI data is filled with zeros.

 For SIO Digital In module, the PDI data is fixed at 1-byte. A high voltage on the IO-Link port C/Q

Pin results in a 0x01 PDI data; a low voltage on the C/Q Pin results in a 0x00 PDI data.

 For SIO Digital Out module, the PDO data is fixed at 1-byte. A zero output value from an SIO

Digital Out module sets the IO-Link port C/Q pin to low voltage. Any non-zero output value sets the C/Q pin to high voltage.

IO-Link Port modules are allowed in Slot 1 to 4 on the MD 748I-11-42/L5-2222 model, or Slot 1 to 8 on the MD 248i-12-8K/L4-2R2K models. Slot 1 is corresponding to IO-Link Port 1. Slot 2 is for IO-Link Port 2, so on and so forth.

If a slot is unpopulated, the corresponding IO-Link port is not configured. That port uses the previously configured settings, or default settings if it has not been configured before.

3.7.1.1 IO-Link Port Settings Additional IO-Link port settings can be configured by using module parameters.

3.7.1.2 IO-Link Port Module Parameters Use the following information to configure IO-Link port module parameters.

1. Double-click an IO-Link Port module.

2. Select the Parameters table. Available parameters are shown in the following figure and the table

describes how to use the parameters.

Leuze electronic MD 748i / MD 248i 26

3 Configuring the IO-Link Master with STEP 7

IO-Link Port Module Parameters

IO-Link Port Config

Minimum Cycle Time (Default: 4)

Valid range: 4-538ms

The minimum or fastest cycle time at which the IO-Link device may operate. You can leave the Minimum Cycle Time set to the default value and the IO-Link

Master negotiates with the IO-Link device for its minimum cycle time. The IOLink Diagnostics page displays the Actual Cycle Time, which is the negotiated cycle time.

Data Storage Config

Automatic Data Storage Upload Enable

Default

: Off

When this option is initially set to On, the IO-Link Master saves the data storage (if the data storage is empty) from the IO-Link device to that port. Some IO-Link devices update the data storage contents if you use the Teach buttons on the IO-Link device, but that is determined by the IO-Link device manufacturer.

Automatic upload occurs when the Automatic Upload Enable option is set to On and one of these conditions exists:

• There is no upload data stored on the gateway.

• The IO-Link device executes a requests_ at upload function (generally

because you have changed the configuration via Teach buttons).

Do not enable both Automatic Upload and Automatic Download at the same time, the results are not reliable among IO-Link device manufacturers.

When a port contains data storage for an IO-Link device and if you attach a device whose Vendor and Device ID do not match, the IO-Link LED on the IOLink Master flashes red to indicate a wrong device is attached. In addition, the IO-Link Diagnostics page displays DV: Wrong Sensor in the IOLink State field.

You should not enable Automatic Upload until after you have configured the IOLink device attached to the port unless you want to capture the default settings. Refer to 10.1 Data Storage for more information.

Leuze electronic MD 748i / MD 248i 27

3 Configuring the IO-Link Master with STEP 7

IO-Link Port Module Parameters

Automatic Data Storage Download Enable

Default

: Off

The data stored on the IO-Link Master port is downloaded to the IO-Link device if:

1. This option is selected.

2. The data stored on the IO-Link Master port contains the same Vendor ID and Product ID as the IO-Link device connected to the port.

3. The data stored on the IO-Link Master port is different than that of the IO-Link device.

4. The IO-Link device requests an upload and the Automatic Upload Enable option is set to Off.

If you change configuration parameters on the IO-Link device and want the parameters to remain loaded on the IO-Link device, you must disable the Automatic Download option because otherwise the IO-Link Master will reload the data storage on the port down to the IO-Link device.

Do not enable both Automatic Upload and Automatic Download at the same time, the results are not reliable among IO-Link device manufacturers.

Validation Config

Device Validation Mode (Default: None)

Device Validation Mode provides these options:

• None - this disables Device Validation Mode.

• Compatible - permits a compatible IO-Link device (same Vendor ID and

Device ID) to function on the corresponding port.

• Identical - only permits an IO-Link device to function on the corresponding port as defined in the following fields.

 Vendor ID  Device ID  Serial Number

Vendor Id (0-65535)

This is required if you select a Device Validation Mode other than None.

Device Id (0-16777215)

This is required if you select a Device Validation Mode other than None. Serial Num

This is required if you select Identical for the Device Validation Mode.

Data Validation Mode (Default: None)

There are three Data Validation Modes:

• None - no data validation is performed on the port.

• Loose - the slave device's PDI/PDO lengths must be less than or equal to the

user-configured values.

• Strict - the slave device's PDI/PDO lengths must be the same as the user- configured values.

PDI Length (0-32)

This is input length of the PDI data field. This is required if you select a Data Validation Mode other than None.

PDO Length (0-32)

This is input length of the PDO data field. This is required if you select a Data Validation Mode other than None.

3.7.1.3 SIO Digital In/Out Module Parameters Use the following procedure to configure SIO digital in/out module parameters.

3.7.2.1 IO-Link Status Module IO-Link Status module is a 4-byte input only module that provides status information of all IO-Link ports.

The following table shows the data format of IO-Link Status module.

Each IO-Link port is mapped into one bit of each byte in the IO-Link Status module as shown in this table. For IO-Link Active status byte (offset 0), a bit one means the corresponding IO-Link port is active. An IO-Link port is considered as active when it is configured correctly and has a working IO-Link device

attached. A bit one in IO-Link PDI Valid status byte (offset 1) means the PDI data from the corresponding IO-Link

port is valid. PDI Valid is only applicable to IO-Link port modules that have input data.

 If there are any errors detected when communicating with the IO-Link device, the corresponding

bit in the IO-Link Error status byte (offset 2) will be set to 1.

 If a high voltage is detected on the auxiliary input of an IO-Link port, the corresponding bit in the

IO- Link Auxiliary Input status byte (offset 3) will be set to 1.

See the following table for the description of each byte of the IO-Link Status module.

3.7.2.2 Digital I/O Module Digital I/O module has 1-byte input and 1-byte output. There are a total of four digital I/O ports: DIO 1-4

on applicable models (MD 248i-12-8K/L4-2R2K). DIO 2 and DIO 4 can be configured as outputs. Use the following table to map DIO pins into bits of Digital

IO module. For input, a bit one means that high voltage is detected on that DIO pin. A zero means low voltage is

detected on the DIO pin. Bits 4-7 are not in use and always return as zeros.

To use DIO 2 and DIO 4 as outputs, first they need to be configured as digital output. Use the following procedure to configure digital output.

1. Double-lick the Digital I/O module to open up the

figure.

2. Change the parameter Mode of DIO 2 and DIO 4 to Digital Output.

Once configured, writing a one to Bit 1 and Bit 3 of the Digital I/O module output sets DIO 2 and DIO 4 pins to high. Clearing Bit 1 and Bit 3 to zero sets DIO 2 and DIO 4 pins to low.

Note: Only Bit 1 and Bit 3 of the Digital I/O module output are in use. Changing the value of other bits has

no effects.

5 Updating Images and Applications

IO-Link Master Images

U-Boot Bootloader

U-Boot is a high-level Bootloader that has networking and console command line capabilities. Among other things, it implements a TFTP server and Leuze electronic Corporation's new discovery protocol.

This verifies that a Linux kernel image exists in NAND, then copies it to RAM and starts the IO-Link Master. The U-Boot version is displayed after the image name.

FPGA

The FPGA partition/image contains configuration data used by programmable hardware within the IO-Link Master unit. FPGA images are unique to the hardware and protocol type. Make sure you download the correct image for your platform.

5 Updating Images and Applications

This chapter provides an overview of the software (images and applications) on the IO-Link Master. In addition it contains procedures to update images and application subassemblies.

5.1 Images and Application Subassemblies Overview The IO-Link Master is loaded with the latest images at the factory but you may need to update images or

application subassemblies to have access to the latest features. You can view all image and application versions in the IO-Link Master ADVANCED | Software page.

Figure 22: IO-Link master software update

5.1.1 Images The following table discusses IO-Link Master images.

Leuze electronic MD 748i / MD 248i 40

5 Updating Images and Applications

IO-Link Master Images

uImage Primary/ Backup

The uImage contains the Linux kernel and the RAM-resident root file system. It does not contain industrial protocol support or application-specific features.

There is a Primary and Backup version loaded on the IO-Link Master. The IO-Link Master automatically reloads the Backup uImage if the file system corrupted.

The uImage version is displayed after the Primary/Backup uImage.

Application Base

The Application Base image comprises a flash-resident file system containing applications and protocol support.

The Application Base is built from a collection of application subassemblies -- each of which may be updated individually between releases of the application base as a whole.

The application subassemblies in the Application Base image are displayed in the lower portion of the SOFTWARE page.

The Application Base assembly has a 3-tuple version number: (for example, 1.3.18).

web-user-interface

The web interface version loaded on the IO-Link Master.

5.1.2 Application Subassemblies Application subassemblies are the components of the Application Base image. Application

subassemblies have a 4-tuple version number (for example, 1.3.18.3). The first two values in a subassembly version correspond to the version of the application base assembly for which it was built and tested.

For example, a subassembly with version 1.3.18.3 was tested with application base version 1.3.18. When using the Software page or PortVision DX, an application subassembly can install only if its version number matches that of the installed application base assembly. A subassembly with a version of

1.20.2.4 only installs if the application base version is 1.20.2. It will not install on a device with application base version 1.21.5.

5.2 Using the Web Interface to Update Software The upper portion of the Advanced | Software page is used to update the IO-Link Master images. The

lower portion of this page is used for updating application subassemblies that are integrated in the Application Base.

Typically, the latest application subassemblies are available in the Application Base image. There may times when a feature enhancement or bug fix is available in an application subassembly and not yet available in the Application Base image.

information for ports with valid IO-Link devices attached. The Configuration Summary page retrieves information that resides on the IO-Link device from the manufacturer.

A file name displayed in the IODD Name field for a port indicates that a valid IODD file is associated with that device. If the field is empty, that indicates that a valid IODD file has not been loaded.

You can review complete IODD file information on a port by port basis by clicking the MORE button next to the port in question or by clicking the PORT menu selection in the navigational bar.

Use the following steps to access the IO-Link Device Configuration Summary page.

1. Click Attached Devices.

2. Click SUMMARY.

Note: The Configuration Summary page takes several minutes to completely load as each device is

queried.

3. Click the MORE button or the corresponding Port (in the navigational bar) to configure the IO-Link

device parameters for a specific device. See chapter 9 Configuring IO-Link Devices for more information.

This chapter discusses using the Attached Devices | Port pages to change IO-Link device parameters.

Note: Optionally, you can use traditional methods such as: PLC interfaces to configure the IO-Link devices.

9.1 Port Pages Overview You can use the Attached Devices | Port page for a port to review and easily edit the IO-Link device

configuration.

Figure 37: IO-Link port overview page

The Port page provides two IO-Link device configuration methods:

 IO-Link Device Port table (GUI), which depends on the appropriate IODD file loaded from the IO-

Link device manufacturer onto the IO-Link Master. To use the IO-Link Device Port table for configuring IO-Link devices, refer to the following subsections:



Editing Parameters - IO-Link Device - Port Table



10 Utilizing IO-Link Master Features

This chapter discusses using the following features:



Data Storage (automatic and manual) to upload or download IO-Link v1.1 device parameters



Device Validation (identical or compatible) to dedicate a port or ports to specific IO-Link devices



Data Validation (strict or loose) to verify data integrity



Menu Bar Hover Shows Submenu, which provides an option to navigate the submenu structure quickly.

Note: You must configure data storage, device validation, data validation in PROFINET IO using Step 7.

You can use data storage on the web page for temporary data storage related tasks.

10.1 Data Storage Data storage is typically supported by IO-Link v1.1 devices.

parameters from an IO-Link device to the IO-Link Master and/or download parameters from the IO-Link Master to the IO-Link device. This feature can be used to:

 Quickly and easily replace a defective IO-Link device  Configure multiple IO-Link devices with the same parameters as fast as it takes to connect and

disconnect the IO-Link device

To determine whether an IO-Link (v1.1) device supports data storage, you can check one of the following:

 IO-Link Diagnostics page - check the Data Storage Capable field to see if it displays Yes.  IO-Link Configuration page - check to see if UPLOAD and DOWNLOAD buttons display under

the Data Storage Manual Ops group. If only a Clear button displays, the device on the port does not support data storage.

10.1.1 Uploading Data Storage to the IO-Link Master The IO-Link device manufacturer determines which parameters are saved for data storage. Remember,

the IOL-Link device should be configured before enabling data storage unless you are using data storage to back up the default device configuration.

There are two methods to upload Data Storage using the Configuration | IO-Link page:



Automatic Enable Upload

storage (if the data storage is empty) from the IO-Link device to that port. Some IO-Link devices update the data storage contents if you use the Teach buttons on the IO-Link device, but that is determined by the IO- Link device manufacturer.

When this option is enabled and another IO-Link device (different Vendor ID and Device ID), the IO-Link Diagnostics page displays a red, indicating a hardware fault.

Automatic upload occurs when the Automatic Upload Enable option is set to On and one of these conditions exists:

 There is no upload data stored on the gateway.  The IO-Link device executes a requests_ at upload function (generally because you have

changed the configuration via Teach buttons).

You should not enable Automatic Upload until after you have configured the IO-Link device attached to the port unless you want to capture the default settings.

- If a port is set to On for this option, the IO-Link Master saves the data

DV: Wrong Sensor

Note: Do not enable both Automatic Upload and Download at the same time, the results are not reliable among

IO-Link device manufacturers.



Data Storage Manual Ops: UPLOAD

from the IO-Link device to that port. The content of the data storage does not change unless it is uploaded again or cleared. Another IO-Link device with a different Vendor ID and Device ID can be attached to the port without causing a hardware fault.

- Selecting the UPLOAD button saves the data storage

12.1 Sample IO-Link Master Gateway Configuration This section demonstrates how to configure and use an IO-Link gateway.

Figure 53: IO-Link Master Gateway Configuration

 The first IO-Link device, which supported 2 bytes of PDI data, was connected to IO-Link Port 1. The

PDI data were mapped into the process image at address IW 5 of the IO controller, as shown in the figure above. The IO controller could read the current PDI data from the IO-Link device at IW 5.

 The second IO-Link device, which supported 2 bytes of PDI data and 2 bytes of PDO data, was

connected to IO-Link Port 2. The PDI data were mapped into the process image at address IW 7. The PDO data were mapped into process image at address QW 2. The IO controller could access PDI and PDO via the two memory locations.

 IO-Link Port 3 and Port 4 were configured as SIO Digital In and SIO Digital Out. The IO controller

could read the input status of the C/Q pin of Port 3 at IB 9, and set the output C/Q pin value of Port 4 by writing to QB 3. IO-Link port status was reported through the module in Slot 9. The 4-byte port status was available at IB 0 to IB 3.

 A Digital I/O module was plugged in Slot 10. DIO 2 and 4 were configured as digital outputs. The IO

controller could reads digital input status at IB 4 and set digital output at QB 0.

Using a variable table, as shown in the following, we monitored and modified the IO data directly.

IB 0-3 were input data from IO-Link Status module (Slot 9). IB 0 was IO-Link Active, IB 1 was PDI Valid, IB 2 was Auxiliary Input, and IB 3 was IO-Link Error. According to the current value of IB 0, Ports 1-4 were active. IB 1 showed the PDI data of Ports 1-3 were valid. Port 4 was an output module therefore; the PDI valid bit was zero. IB 2 showed that the auxiliary input pins of Port 1-4 were high. No errors were detected so IB 3 was zero.

The PDI data of Port 1 was 0x090E (IW 5). The PDI data of Port 2 was 0x03F6 (IW 7). In this example, we used wires to connect the C/Q pin and auxiliary input pin of Port 3 and Port 4 together,

creating a testing loopback. Then we changed QB 3 to 0x01, which set the C/Q Pin of Port 4 and both auxiliary input pins of Port 3 and 4 to high. IB 9 showed the status of the C/Q pin of Port 3 was high (0x01). The high status of auxiliary input pins of Ports 3 and 4 was reflected in IB 2.

To test digital I/O ports, we created testing loopbacks by connecting DIO 1 to 2, and DIO 3 to 4 with wires. Then we changed QB 0 to 2#0000_1010, which set the DIO 2 and DIO 4 to high. IB 4 showed the input status of DIO 1-4 were high (2#0000_1111).

Slot 5-8 (Port 5-8) and Slot 11 were open. They could be used by another IO contr oller via a second application relationship.

12.2 Read PDI Data as Record Data For IO modules that have input data, the Port Qualifier and PDI data can also be read by using the

SFB52 RDREC (read record). The following table shows the available record read indexes for the IOLink Master.

Available Record Read Index for MD 248i-12-8K/L4-2R2K

Using the same example in 12.1 Sample IO-Link Master Gateway Configuration; a record read request of 2-bytes at index 100 would return the current PDI data of the IO-Link device attached to Port 1. A record read request of 1-byte at Index 900 would return the current IO-Link port active status.

Reading partial PDI data via record read request is supported. For an instance, an IO-Link device that supports 32-bytes PDI data is connected to IO-Link Port 5. A record read request of 32-bytes at Index 500 returns the whole 32-bytes of PDI data. Another record read request of 4-bytes at Index 529 returns the last 4-bytes of the PDI data. This provides flexibility in being able to get only the interested data from a large PDI data block.

If a record read requests more data than the IO module or IO-Link device supports, IO-Link Master returns the available PDI data and fills the remaining data with zeros. Again using the same example in

12.1 Sample IO-Link Master Gateway Configuration; a record read request of 4-bytes at Index 100 returned 0x09 0x0E 0x00 0x00, where 0x09 and 0x0E were the actual PDI data.

IO-Link Master returns an error if a record read request contains an invalid index. Writing PDO Data to an IO-Link device via data record write service is not supported. This is because

that the new PDO data written by a record write will only last for one update cycle. The next cycle the IO controller overwrites the new PDO data with the old cyclic data from the process image.

12.3 Using the SFB52 RDREC To use the SFB52 RDREC, specify the index of the requested module in INDEX. Specify the maximum

number of bytes you want to read in MLEN. The selected length of the target area RECORD should have at least the length of MLEN bytes.

TRUE on output parameter VALID verifies that the data record has been successfully transferred into the target area RECORD. In this case, the output parameter LEN contains the length of the fetched data in bytes.

The output parameter ERROR indicates if a data record transmission error has occurred. In this case, the output parameter STATUS contains the error information.

12.4 Read and Write ISDU with the FB IOL_CALL The function block IOL_CALL represents the conversion of the communication standardized for the IO-

Link technology to and from IO-Link devices. The IO-Link Master supports the IOL_CALL function block. It can be used to access an ISDU of an IO-Link device.

The IOL_CALL function block and the library description are available at: http:// support.automation.siemens.com/WW/view/en/82981502

To use IOL_CALL function block, do the following:

Leuze electronic MD 748i / MD 248i 85

12 PROFINET IO Reference Information

Figure 56: IOL_CALL Function Block

1. Set CAP to 255.

2. Specify PORT to be the IO-Link port number (1 to 8) at which the IO-Link device is connected.

3. Set IOL_INDEX and IOL_SUBINDEX to be the index and subindex of the requested ISDU.

RECORD_IOL_DATA requires the full specification of the DB parameters, i.e. P#DB1.DBX0.0 byte

232. The target area RECORD_IOL_DATA must have enough available bytes to hold the requested ISDU block up to 232 bytes.

4. Set RD_WR to 0 for read and 1 for write. For write, also specify the length of the data to be written

in LEN. A positive edge on REQ starts the IOL_CALL request.

BUSY is set to 1 when the IOL_CALL request is in progress. Once completed, DONE_VALID is set to 1 if there was no error. Otherwise, ERROR is set and STATUS and IOL_STATUS contain the error information. For the remainder of the IOL_CALL function block parameters and complete error information, refer to the IOL_CALL library description.

The IOL_CALL function block has a 20 seconds timeout value. If the request takes longer than 20 seconds, the process is aborted and a timeout error is returned. The IO-Link Master also has a timeout value for IOL_CALL request. The default timeout value is 20 seconds. It can be changed through the web page (Configuration -> PROFINET IO).

12.5 Diagnostic Alarm Events from IO-Link Master and IO-Link devices are mapped to PROFINET alarms and channel

diagnostics according to the IO-Link on modifications.

12.5.1 IO-Link Event Mapping Overview IO-Link events are mapped into PROFINET Alarms and Channel Diagnostics using the following table.

Each appearing IO-Link event (mode Coming) results in adding channel diagnostics. Each disappearing IO-Link event (mode Going) results in removing channel diagnostics. IO-Link events that have mode Single will be mapped to PROFINET process alarm.

In addition, only IO-Link events that have the type of Error or Warning are mapped to PROFINET channel diagnostics. Type Message IO-Link events are not mapped.

12.5.2 IO-Link EventCode Mapping

PROFINET Working Document Version 13.4.2015

with some

IO-Link events that are generated by IO-Link devices (remote events) are mapped to PROFINET diagnostics using ChannelErrorType 0x500 and0x501.

 For an EventCode that is between 0x0000 and 0x7FFF, ChannelErrorType 0x500 is used. The

EventCode is directly mapped to ExtChannelErrorType.

 For an EventCode that is between 0x8000-0xFFFF, ChannelErrorType 0x501 is used. The

EventCode is mapped to ExtChannelErrorType with the MSB set to 0.

 For IO-Link events that are generated by IO-Link Master (local events), ChannelErrorType 0x502

is used. EventCode is directly mapped to ExtChannelErrorType.

The following table summarizes how IO-Link EventCode is mapped to PROFINET diagnostics.

13 Troubleshooting and Technical Support

This chapter provides the following information:



Troubleshooting



IO-Link Master LEDs



Contacting Technical Support



Using Log Files

13.1 Troubleshooting Before contacting Technical Support, you may want to try the following:

 Check to make sure LEDs are not reporting an issue using IO-Link Master LEDs  Verify that the network IP address, subnet mask, and gateway are correct and appropriate for

the network. Make sure that the IP address programmed into the IO-Link Master matches the unique reserved IP configured address assigned by the system administrator.

 If using DHCP, the host system needs to provide the subnet mask. The gateway is optional

and is not required for a purely local network.

 Remember that if the rotary switches on the MD 748I-11-42/L5-2222 are set to a non-default

position, the rotary switches override the lower 3 digits (8 bits) of the static IP address configured in the Network page.

 Verify that the Ethernet hub and any other network devices between the system and the IO-

Link Master are powered up and operating.

 Verify that you are using the correct types of cables on the correct connectors and that all cables

are connected securely.

 Disconnect and re-connect the IO-Link device, or optionally, use the Configuration | IO-Link page

to Reset the port, and then set the Port Mode back to IO-Link.

 Reboot or power cycle the IO-Link Master. Use the Advanced | Software page to reboot the IO-

Link Master.

 Verify that the Port Mode matches the device, for example: IO-Link, Digital In, Digital Out, or

Reset (port is disabled).

 If you are receiving an error that indicates a hardware fault, check the Configuration | IO-Link

page for the port experiencing the fault.  Check the settings for the Automatic Upload Enable and Automatic Download Enable options.

If the Vendor ID or Device ID of the attached device does not match, a hardware fault is generated.

 Make sure if the port contains data storage that the Vendor ID and Device ID match the

device attached to the port. If it does not, CLEAR the data storage or move the device to another port.

 Check the Device Validation and Data Validation settings. If the attached device does not

meet these settings, a hardware fault is issued.

 Open the IO-Link Master web interface and review the following pages to see if you can locate a

problem:

 IO-Link Diagnostics  Digital I/O Diagnostics  PROFINET IO

 If you have a spare IO-Link Master, try replacing the IO-Link Master.
