PD-01 PROFIBUS-DP Module

Chapter 4 Communication

NOTE:

Before reading this chapter, make sure you read chapter 3 and understand the installation of PD-01.

PROFIBUS address

PD-01 has two rotary switches to set the PROFIBUS address, the only way for user to set the address.

The address switches, ADDH and ADDL, allow user to set the address in a HEX format. ADDH is used to set high 4 bits of address, and ADDL is used to set low 4 bits of address. If both ADDH and ADDL are set to F, and PD-01 is power ON or re-power ON, then PD-01 will enter the TEST mode, the SP LED and NET LED will be in steady orange.

Address

Meaning

1..0x7D

Valid PROFIBUS address

0 or

Invalid PROFIBUS address

0x7E..0xFE

 

0xFF

Enter TEST mode

NOTE:

Setting changes via address switches will not effective when PD-01 is operating. This means the setting changes will effective after PD-01 power re-boot. Please understand this cold restart must be initiated by toggling the power to OFF and then ON.

Parameters setting in VFD series Drives

PD-01 is designed to communicate with VFD series Drives via MODBUS communication port. Prior to the connection, users have to set parameters below in VFD series Drives:

Set the communication protocol of VFD series Drives to RTU 8, N, 2. Set the baud rate of VFD series Drives to 9600bps.

Set the frequency source for VFD series Drives to operate via RS485.

Set the operation source of VFD series Drives via MODBUS communication.

Refer to the following table for the above settings when connecting to VFD series Drives:
