*Attention: The IO-Link Master >IOLG2< is discontinued and not available anymore.*

To be able to read and write ISDU data using the IOLG2 IO-Link Master in an Ethernet/IP network you need to integrate the master into your Studio 5000 project.

The first steps and the basic configuration is shown in this video tutorial:
www.sick.com/de/de/p/p389646  --> Videos

The basic principle of the ISDU communication is shown in chapter 6.3 (page 29) in the user manual. The user manual is found under the same link as above  -->  Downloads  -->  Literature.

Step by step: Using Messages in Locix Designer (Studio 5000):

1.   Create two arrays as Controller or Local Tag

a.   One to receive the data out of an ISDU

b.   One to send an ISDU command

Since the maximum possible size of an ISDU is 232Byte we use SINT arrays of 232 Byte size in this example.

2.   Create two messages in your Tag list:

3.   Configure the messages as shown in the screenshots:

You find the used values in the user manual.
Attribute   3 = READ
                 2 = WRITE

Source Element is the Array you created before for sending commands and data.
Source Length is the number of bytes you like to read or write. For reading it doesn’t matter if the value is bigger than the ISDU you are reading. For writing it has to match.
Destination Element is the Array you created to receive ISDU data.

Use the button “Browse” to select the Path of the IOLG2 IO-Link Master.

The message for writing needs to be configured in the same way (besides Attribute and Source Length)

4.   The message needs to be called in your source code.

a.   Using ST coding

b.   Using Ladder diagram

5.   Define the ISDU command

a.   READ - Example

b.   WRITE - Example

6.   Start the READ or WRITE operation by enabling your trigger.

Here the example for the ST code snippet from above:

7.   For READ operations you find the data in your receive array

Reading and writing of ISDU data is easier if you use function block which is provided by SICK. On how to use these function blocks please refer to the manual in the ZIP package of the function block itself.
