Chapter 2 Introduction
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.
The PROFIBUS family comprises three types of protocol, PROFIBUS-DP, PROFIBUS-PA and
PROFIBUS-FMS, each of them is used for different tasks:
PROFIBUS-DP (Decentralized Periphery): PROFIBUS-DP is a rapid and low cost
communication connection designed for high-speed data transmission at field level.
PROFIBUS-DP has widespread usage for such items as remote I/O systems, motor
control centers, and variable speed drives. It is designed and optimized especially for
communication between automation systems and decentralized peripheral devices.
PROFIBUS-PA (Process Automation): PROFIBUS-PA is the PROFIBUS solution for
process automation, typically with MBP-IS transmission technology. Based upon
PROFIBUS-DP, PROFIBUS-PA is an extension of the PROFIBUS-DP protocol for data
transmission. It is designed to support intrinsically safe applications and can be used
within hazardous areas, with high explosion risk using intrinsic safe MBP-IS interface.
PROFIBUS-PA is used to connect sensor and controller to the bus.
PROFIBUS-FMS (Fieldbus Message Specification): PROFIBUS-FMS is multiple
master communications designed for communication at the cell level. It is designed for
acyclic or cyclic data transfers at medium speed between control equipment and
cell-level controllers. FMS services open up a wide range of applications and offer a
wide range of functionality and flexibility.
The Maximum cable length in a segment depends on the transmission speed. PROFIBUS-DP
communicates at speeds from 9.6 Kbps to 12 Mbps over distances from 100 to 1,200 meters.
Baud Rate

PD-01 PROFIBUS-DP Module
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 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
0x7E..0xFE
0xFF Enter TEST mode
Invalid PROFIBUS address
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.

Examples for PKW mechanism
Example 1: Read data of parameter P0003
To read value of P0003, set the request ID to 1 (request parameter value - word).
Because P0003 is less than 2000, the Para Page Select is 0, thus, the data sequence
are as follows:
Master PD-01 : 1003 0000 0000 0000 request value of P0003
PD-01 Master : 1003 0000 0000 1770
Request Response
Word 1 (PKE) 1003
Word 2 (IND) 0000
Word 3 (PWE1) 0000
Word 4 (PWE2) 0000
Word 1 (PKE) 1003
Word 2 (IND) 0000
Word 3 (PWE1) 0000
Word 4 (PWE2) 1770
PD-01 responds the value of P0003. All parameters in VFD series Drives are 16-bit
value, so the value is transferred in PWE2 (4th word). The value of P0003 is 0x1770
(6000 decimal), in VFD-M series Drives, it is “Maximum Output Frequency”.
Example 2: Read command frequency in VFD series Drives (0x2102)
To read value of command frequency, set the request ID to1, we should set the Para
Page Select because the parameter address is greater than 2000. The address
0x2102 is 8450 in decimal, if set Page Select to 4, then the Basic PNU is 8450 –
4*2000 = 450 (0x1c2), thus, the data sequence are as follows:
Master PD-01 : 11C2 2000 0000 0000 request value of address

Example 3: Write data 2 to parameter P0804
To write data to P0804, request ID is set to 2 (Modify parameter value - word), Para
Page Select should be set because the parameter address is greater than 2000. The
address of P0804 is 0x0804, which is 2052 in decimal, if set Page Select to 1 (bit 15
of IND is 1), then the Basic PNU is 2052 – 1*2000 = 052 (0x34), thus, the data
sequence are as follows:
Master PD-01 : 2034800000000002 write data to P0804

Word 4 (PWE2) 0002 Word 4 (PWE2) 0002
All parameters values in VFD series Drives are 16-bit, so the data may be transferred
in PWE2 (4th word).
NOTE:
VFD series Drives will write the data to EEPROM. When using PKW to change the
value of parameter, the data will be written to EEPROM directly. However, if this
action is too often, the EEPROM will have no capability of directly saving data.
So please pay close attention on it.
Example 4: Read diagnostic data
User can use the special address to read the current diagnostic data. Please refer to
Section 6.2 for details. The diagnostic address starts from 0x7500 to 0x7504 (5
words). To read diagnostic data in these addresses, request ID is set to 1, Para Page
Select should be set because the parameter address is greater than 2000. The
address 0x7500, which is 29952 in decimal, if set Page Select to 14, then the Basic
PNU is 29952-14*2000=1952(0x7A0), thus, the data sequence are as follows:
Master - > PD-01 : 17A0700000000000 read data from 0x7500
PD-01 - > Master : 17A0700000000300

If PD-01 returns the data 0x0300, it indicates that Scan port is disconnected. Please
refer to Section 6.2 for details.
Example 5: Access error
If take any action using PKW to access parameter in AC Drives and it fails, PD-01 will
response error information. Suppose that Master send data sequence is 202D 8000
0000 0002, if VFD series Drives does not find this address (0x07FD), it will respond
the data sequence 702D 8000 0000 0000, response ID is 7 which means cannot
process request (with error number), and error number is 0 (Illegal Parameter

Response time about PD-01
The update time via PROFIBUS connection can be divided in 3 parts:
T1: Communication time in transmit data from the master to PD-01, and
T2: Wait processing in data buffer of PD-01, and
T3: Communication time in transmit data from PD-01 to VFD Drives.

T2
19
PD-01 PROFIBUS-DP Module
T1 depends on the actual transmission speed and the type of master in use.
T2 depends on the internal timer of PD-01. Data is transmitted to VFD series Drives per
70ms triggered by a timer. User cannot change the time-out interval.
T3 depends on the Modbus communication between PD-01 and VFD series Drives.
So the update time is,
Max update time = T1 + T2 (70ms) + T3
In fact, the actual update time is less than the Max update time. If the timer time-out
when the data arrive PD-01, PD-01 will save the data to data buffer, and transmit the data
to VFD series Drives immediately.

9 d_state UINT
This is a flag. If address in Data Output 1 ~
0x0001
Data Output 4 is continuous, set it to 1, and
set the others to 0.
10 din_len UINT
This is a length, and unit is word. It specifies
0x0002
the length of PD-01 to process data in PZD, if
user select the Module = "4 PKW, 4 PZD", but
din_len is 3, PD-01 will process 3 word and
ignore the 4th word.
11 dout_len UINT
This is a length, and unit is word. It specifies
0x0002
the length of PD-01 to monitor data from AC
Drive, if user select Module = "4 PKW, 4

word and ignore the 4th address.
12 LossDPComTreat UINT
This variable indicates that the PD-01 will
0x0001
take action when communication with
Profibus network is lost, the value can be
assigned as follows:
00 – Ignore event and continue;
01 – Stop according to Pr “Stop Method” in
VFD series Drives.

Item Name Type Description Default
13 LossSPComTreat UINT
This variable indicates that the PD-01 will
0x0000
take action when the SP communication
(SCANport communication) is lost, the value
can be assigned as follows:
00 – Stop data exchange and report fault;
01 – Continue data exchange and report
alarm;
02 – Ignore and continue data exchange.
If the address in Data Output 1 ~ Data Output 4 is continuous, then set d_state to 1, PD-01
will get starting address from Data Output 1. The next data will be got from the address next
to the starting address, and the reading length is determined by dout_len. If the MODBUS
address for reading is discontinuous, please set d_state to 0, PD-01 will also get starting
address from Data Output 1, but the difference is the other data will be got from the address
saved in Data Output 2, Data Output 3 and Data Output 4 in order.
Example, if
Data Output 1 = 0x2100;
Data Output 2 = 0x2101;
Data Output 3 = 0x2102;
Data Output 4 = 0x2103;
dout_len = 0x0003;
The MODBUS address in Data Output 1~Data Output 4 is continuous, so you can set the
d_state to 1, then PD-01 will monitor the address starting from Data Output 1, and monitor 3
words from VFD series Drives one time. When the dout_len is 3, PD-01 will ignore the
address in Data Output 4. If d_state is set to 0, PD-01 will read data from the address in Data
Output 1, and read data from the address in Data Output 2, and so forth.

Edit the user parameters in S7 Step hardware configuration tools shown below:
NOTE:
Please do not set d_state to 1 when the address in Data Output 1 ~ Data Output 4 is
non-continuous to avoid Parameterization error and IO disconnect. The PD-01 just check the
address starting from Data Output 1 to Data Output [dout_len-1], in other words, if the
address in Data Output 1 ~ Data Output 3 is continuous, but the address in Data Output 4 is
not, and dout_len is 0x0003, then the check still can pass.

Be sure to set other value and energize PD-01 again.
Troubleshooting via diagnostic data
PD-01 provides 16 bytes diagnostic data when the alarm occurs and when user parameter
setting “LossSPComTreat” is set to “Continue data exchange and report alarm”. It includes 6
bytes standard diagnostic data and 10 bytes device related diagnostic data. The following
table shows the meanings of the 16 bytes:
Byte 1-6 Byte 7 Byte 8 Byte 9 Byte 10
Byte 16
Standard
diagnostic data
Byte 7 indicates the length of device related diagnostic data including itself, so if byte 7 is 10
(0Ahex), it indicate device related to diagnostic data have 10 bytes (including byte 7).
Length in bytes SP communication
status
Error code Reserved
Byte 8 indicates the SP communication status when the alarm occurs, and the valid value
should be as follows:
30
DELTA ELECTRONICS, INC. ALL RIGHTS RESERVED
PD-01 PROFIBUS-DP Module
00 – Normal
01 – CRC check failure
02 – VFD series Drive returns error code
03 – Communication is time out and disconnected
Byte 9 indicates the error code when byte 8 is 02 (VFD series Drive returns error code). Refer
to the Section 6.3 for the meanings of invalid code.
Other word, user can get the diagnostic data via PZD area any time. PD-01 provides some
special MODBUS addresses to indicate the diagnostic status, the address assignments are
as following:

User can get these data through “Data Output 1”, or 2, or 3, or 4 in user parameters. For
example, if set the “Data Output 1” to 0x7500 means get the diagnostic data from 0x7500,
and get the return data from address 0x7500 in 1st word of PZD area.
NOTE:
These special addresses are read-only, it will fail if user tries to write data to it.
Troubleshooting via error codes
If there is a communication error detected between PD-01 and VFD series Drives, the error
code will be displayed on the digital keypad of VFD series Drives.
VFD series Drives can process the message from PD-01 if the communication setting is valid.
But if the command of message is invalid, the VFD series Drives will respond a report
message that has error codes listed in table below, to PD-01.
