OVERVIEW

1、OVERVIEW
This chapter contains a short description of the Profibus standard and PD-301 communication expansion
card information.
1.1 Profibus standard
Profibus is an open serial communication standard that enables data exchange between all kinds of
automation components. Profibus There are three main variations of PROFIBUS: Profibus FMS (Fieldbus
Message Specification), Profibus DP (Decentralized Periphery) and Profibus PA (Process Automation).
The physical transmission medium of the bus is a twisted pair cable (according to the RS-485 standard).
The maximum length of the bus cable is 100 to 1200 meters, depending on the selected transmission rate.
Up to 31 nodes can be connected to the same PROFIBUS network segment without the use of repeaters.
With repeaters, it is possible to connect 127 nodes (including repeaters and master station) to the
network.
In PROFIBUS communication, the master station (usually a PLC) polls the nodes which respond and take
the actions requested by the master. It is also possible to send a command to several nodes at the same
broadcast; in this case the nodes do not send a response message to the master. The PROFIBUS
protocol family is specified in the EN 50170 standard. For further information on PROFIBUS, refer to the
EN 50170 standards.
1.2 PD-301 function
PD-301 is an optional communication expansion device for Shihlin new type inverter which enables the
connection of Shihlin inverter to a PROFIBUS network. The PD301 is considered as a slave on the
PROFIBUS network. Through the PD301, it is possible to:
1、give control commands to the inverter(Start, Stop, Target frequency, Forward/Reverse rotation,
etc.)
2、Send the target frequency
3、Read status information and actual values from the inverter.
4、Read and change the inverter parameter values.
5、Reset at inverter fault.

3、INSTALLATION
3.1 Pre-installation instructions
Make sure that the input power of the inverter is off.
Note: With input power on, do not install or remove the plug-in option. Otherwise, the inverter and plug-in
option may be damaged.
3.2 Node address setting
Set the node address between "1 to 125" by using node address switches on the PD-301. For the setting
larger than 125, the address will be forced to transmitted to 125 by PD-301. When the address is 0,
Profibus slave station node address is invalid. The setting is reflected only when power turns on next time.
Please refer to the following table for address setting:
Switch number (1-8) Actual physical address

4.2 Wiring
(1) Use the network connection cable which supports 12.0Mbps communication.
Strip off the sheath of the Profibus communication dedicated cable and wind wires and shield cables
to use. If the length of the sheath pealed is too long, a short circuit may occur among neighboring
wires. If the length is too short, cables and shield cables might come off.
(2) Loosen the terminal screw and insert the cable into the terminal.
Tighten each cable with fixing screws to the recommended tightening torque.
Wire the stripped cable after twisting it to
prevent it from becoming loose.
In addition, do not solder it.
Use a bar type terminal as required.

COMMUNICATION FUNCTION
14
7、COMMUNICATION FUNCTION
7.1 Profidrive communication protocol
Communication protocol means the way of transmitting control order (control word, status word, given
value and actual value) between the master and the slave. PD-301 adopts Profidrive dpv0 protocol. The
following introduces the control word, status word, given value and actual value in Profidrive
communication protocol. PD-301 doesn’t adopt the control word and status word stated in Profidrive. It
gives a detailed description on the status word and its structure in PD-301.
7.1.1 The control word and the status word
The control word is the principal means for the master station controlling the slave station from a fieldbus
system. It is sent by the fieldbus master station to the inverter, the PD-301 module acting as a gateway.
The inverter switches between its states according to the bit-coded instructions on the control word, and
returns status information to the master in the status word. The structure of the control word and the
status word adopted by PD-301 is shown as the figure below, and the corresponding inverter Modbus
address is: 0x1001.

7.1.2 Given values
Shihlin inverter can receive control information from multiple sources including external terminal analog
signal given, PU panel given and communication module given, etc. For Profibus controlling the inverter,
PD-301 should be defined as given controlling information source. At this point, Profibus bus passing
speed given value will be mapped to the corresponding Modbus communication address, the value is
0x1002.

COMMUNICATION FUNCTION
15
7.1.3 Actual values
Actual Values are words containing information on the operation of the inverter. The functions to be
monitored are selected by a PC network with configuration software. PC gets the present inverter
operation status through reading the value. The monitoring Modbus address is 0x1003.
7.2 Communication information
The PD-301 supports the Profibus DP (DP-V0) protocol according to IEC 61784 and EN 50170 standard.
Profibus DP-V0/DP-V1 is a distributed I/O system which enables the master to use a large number of
peripheral modules and field devices. The data transfer is mainly cyclic: the master reads the input
information from the slaves and sends the output information back to the slaves. The PD-301 uses
so-called PPO (Parameter/Process Data Objects, i.e. parameter / process data object) in cyclic
communication, supporting standard message1, message2. It also adopts custom expansion message
structure.
7.2.1 Service Access Points (SAPs)
The services of the Profibus data link layer (Layer 2) are used by Profibus-DP through Service Access
Points (SAPs). Precisely defined functions are assigned to individual SAP. For further information on
Service Access Points, please refer to the EN 50170 and IEC 61784 standards. The following introduces
