INSTALLATION

For example, to set the node address to 42, set switch A to “2” and switch B to “4”.

When removing the hatch, avoid touching the circuit boards and components. Exercise caution when using tools to open the hatch.

NOTE

Profibus installation procedure

PROFIBUS Each device on a Profibus-DP network is associated with a GSD file, which contains all CONFIGURATION TOOL necessary information about the device. This file is used by the Profibus configuration tool

during configuration of the network. The file is available for download at the GE Multilin website at http://www.GEmultilin.com (the GSD file is named ‘P48509E5.GSD’).

It is necessary to import the GSD file in the Profibus configuration tool in order to incorporate the P485 as a slave in the network. The properties for the P485 must then be configured from the Profibus configuration tool. This includes setting up the node address, input/output data areas and offset address.

•Node address: The node address in the Profibus configuration tool should be set to match the one selected using the on board configuration switches of the P485 (see Configuration switches on page 2–6).

•Setting up input/output data areas: Input/output data are arranged as logic modules in the Profibus configuration tool. Which modules to use depends on the application. The modules are composed together in the “module list” for the P485 device.

It is possible to select modules freely to compose the required input/output sizes, see example below.

Input/output bytes required

Modules

 

 

4 inputs and 2 outputs

4 inputs + 2 outputs

 

 

7 inputs and 12 outputs

4 inputs + 2 inputs + 1 input + 8 outputs + 4 outputs

 

 

68 inputs

64 inputs + 4 inputs

 

 

•Offset address: The offset addresses can be chosen freely. However, certain restrictions may apply depending on what PLC/Profibus master is used.

PROFIBUS NETWORK If the P485 is the last node on a Profibus segment, it is necessary to use a Profibus TERMINATION connector with integrated termination switch.

•The termination switch should be set to ‘ON’ if...

–The P485 is the last physical node on a network segment

–No other termination is used at this end of the network

•The termination switch should be set to ‘OFF’ if...

–There are other nodes on either side of the P485 in the network segment
