Chapter 2 Overview CME-PD01, defined as a communication module for PROFIBUS-DP, is used to link VFD-E series and PROFIBUS-DP system. 2.
PAGE 8
Chapter 2 Overview| CME-PD01 The address in PROFIBUS-DP can be set via two rotary address switches, ADDH and ADDL, on CME-PD01: ADDH used as a high 4 bits of address, ADDL used as a low 4 bits of address. NOTE For more information of address switches, refer to Chapter 5 Communication. A specific 6-PIN communication cable for RJ-45, is used to connect the CME-PD01 to VFD-E series via RS-485 interface. VFD-E series supply the 15V DC power to CMEPD01 through this cable.

Chapter 3 Profibus Introduction 3.1 PROFIBUS PROFIBUS is an international, vendor- independent, opening filed bus standard for a wide range of applications in the fields of manufacturing, production, process and building automation, and other automation control field.
PAGE 10
Chapter 3 Profibus Introduction| CME-PD01 3.2 PROFIBUS-DP PROFIBUS-DP is a PROFIBUS communication profile optimized for high-speed, time-critical data transmission at field level using low-cost connections. PROFIBUS-DP is a suitable substitute for conventional, costly parallel wiring of 24 V measurement signals in production and manufacturing automation, as well as for analog 4(0) to 20mA measurement signals in process automation.

Chapter 4 Installation Information Please make sure that the power of VFD-E series is OFF before installation or remove the CMEPD01 from network. 4.1 Installation Improper installation of the CME-PD01 will cost its life usage. Please follow the instructions to install your CME-PD01 carefully.
PAGE 12
Chapter 4 Installation Information| CME-PD01 Power Supply The power of CME-PD01 is supplied from VFD-E series Drive. The VFD-E firmware version should be V2.02 and above. No external power needed. The +15VDC power is applied to CME-PD01 directly via a specific 6-PIN communication cable (This 6-PIN cable is packed together with CME-PD01). CME-PD01 is energized while the power is applied to the VFD-E series, then the SP LED will be steady green. 4.
PAGE 13
Chapter 5 Communication Please make sure that you have read chapter 4 and fully understood the CME-PD01 installation. 5.1 PROFIBUS Address CME-PD01 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.

Source P02-00=3 Command Source P02-01=3 After these settings completed, connecting CME-PD01 and VFD-E series via communication cable mentioned earlier, CME-PD01 is then energized. Two LEDs will be firstly in orange because CME-PD01 is initialized and test itself. SP LED will be then in steady green since that the connection is established between CME-PD01 and VFD-E series. 5.

Chapter 5 Communication| CME-PD01 NOTE CME-PD01 supports PPO1 and PPO3 structure only. 5.3.2 Extended Configuration In addition to the PPO types, cyclical data can also be configured to EXT CONF 1 or EXT CONF 2 (see table below). These two extended configuration both have four process data words. The areas of consistency can be set flexibly.

Chapter 5 Communication| CME-PD01 NOTE Table above is for reference only, please check VFD-E series user manual for details. CME-PD01 will get the status word from VFD-E series, so the bit assignments in the user manual of VFD-E series is valid. 5.3.5 Accessing Parameters via PKW Area In cyclical data, CME-PD01 can provide request and response (read / write) message to access the VFD-E parameters.

Chapter 6 Parameters Setting in GSD file 6.1 GSD File A GSD file is a text file used to identify PROFIBUS-DP device (Master or Slave), which contains the necessary data for the configuration of DP slaves within a standard DP master. Typical information in a GSD file are Vendor information, supported Baud rates, Timing information, supported Options/features and Available I/O signals. The GSD file is the fundamental building block for the master parameter record.

CME-PD01 will monitor this address, and copy the return data to the 4th word of cyclic input data PZD if selecting module "4 PKW, 4 PZD". 9 d_state UINT This is a flag. If address in Data Output 1 ~ Data Output 4 is continuous, set it to 1 or set it to 0. 0x0001 UINT This is a length, and unit is word. It specifies the length of CME-PD01 to process data in PZD.
