Editing of Configuration

You can change the configuration of PROFIBUS-DP slave module. Change parameters as necessary.

1. Select [Setup] - [System Configuration] and display the [System Configuration] dialog box.

2. Select [Controller] - [Inputs / Outputs] - [Fieldbus Slave] - [General].

   

3. Set the Node address.
   A node address from 0 to 125 is available for the PROFIBUS-DP device.

   Generally, node addresses are recommended to be configured as shown in the table.

   Node address	Device Name
   0	Service unit such as PG/PC
   1	Operation panel such as HMI
   2	Master station
   3-125	DP slave station

4. Change the settings of [Input Bytes] and [Output Bytes].
   The sum of input and output data sizes is restricted as follows:
   For Byte format: 372 bytes
   For Word format: 208 words

5. Click [Apply].

6. Click [Close].
   The following dialog box appears and the Controller automatically starts rebooting.

   

7. Select [Setup] - [System Configuration] and display the [System Configuration] dialog box.

8. Select [Controller] - [Inputs / Outputs].

   

9. Confirm that the following items are displayed in "Fieldbus slave".
   Inputs: "512" - "512 + Changed number of input I/O (Bits)"
   Outputs: "512" - "512 + Changed number of output I/O (Bits)"

   In this example, Input byte is 20 bytes (160 bits) and 512-671 is displayed in Inputs.

   Also, Output byte is 20 bytes (160 bits) and 512-671 is displayed in Outputs.

KEY POINTS

---

When you change the input/output size of PROFIBUS-DP slave module, you need to change the input/output size of the slave information registered in the Fieldbus master device.

Make sure to add the output modules first, and then, add the input modules.

Use the window below to change the input/output size of the slave information registered in the Fieldbus master device by the applicomIO Console application.

16 Bytes Out	Outputs: 20 Bytes
4 Bytes Out
16 Bytes In	Inputs: 20 Bytes
4 Bytes In
