Warning
3
Please read this instruction carefully before use and follow this instruction to operate the device in order
to prevent damages on the device or injuries to staff.
3
Switch off the power before wiring.
3
DVPPF02-H2 is an OPEN TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the
device (e.g. key or specific tools are required for operating the enclosure) in case danger and damage on the
device may occur.
3
DVPPF02-H2 is to be used for controlling the operating machine and equipment. In order not to damage it, only
qualified professional staff familiar with the structure and operation of DVPPF02-H2 can install, operate, wire
and maintain it.
3
DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check
all the wirings again before switching on the power and DO NOT touch any terminal when the power is switched
on. Make sure the ground terminal

3.1 Address Switch
The address switches are two rotary switches, x160 and x161, setting up the node address of DVPPF02-H2
on PROFIBUS DP network. Rotate the switch to a position to indicate the value of the switch. The range for
each switch is 0 ~ F. The address switches are in hexade cimal form. The factor of x16
1
x16
is 161. The set value of the address switch is the sum of the value of each of the two switches multiplied
by its factor.
Value of address switch Value at x161 Value at x160
Factor of address switch 161 160
Example: If you need to set the node address of DVPPF02-H2 to “26” (decimal), simply switch x161 to “1”
0
and x16
to “A”. 26 (decimal) = 1A (hex) = 1 × 161 + A × 160.

The control registers (CR) are the registers inside DVPPF02-H2. See the t able below for the definitions of
all the CRs. DVP-EH2 series PLC MPU can read or write the CR allowed through DFROM/DT O instructions.

4.2 Data Transmission between DVPPF02-H2 & PROFIBUS DP Master
Once a PROFIBUS DP network is established, the data written into the data mapping area in PROFIBUS
DP will be transmitted automatically to the registers st arting from CR#103 in DVPPF02-H2 through PROFIB US
DP bus. The length of data transmitted is decided by the parameter setting, Max. 100 words at a time. The data
in the registers starting from CR#3 in DVPPF02-H2 will be transmitted automatically to the data mapping area
in PROFIBUS DP master through PROFIBUS DP bus. The length of data transmitted is decided by the
parameter setting, Max. 100 words at a time as well. See the table below for the data transmission between
DVPPF02-H2 and PROFIBUS DP master.

M1083 for switching instruction modes in DVP-EH2 series PLC MPU:
1. When M1083 = Off, during the execution of DFROM/DTO, all external and timer
interruption subroutines will be forbidden. The interruptions within are allowed
only after DFROM/DTO finishes its execution. DFROM/DTO CAN
also be used in
an interruption subroutine.
2. When M1083 = On, during the executino of DFROM/DTO, the interruption
occurring will be processed first (with a 100us delay), and the execution of
DFROM/DTO will be stopped. After the interruption subroutine finishes its
execution, the program will jump to the next instruction. Besides, DFROM/DTO
CANNOT
be used in an interruption subroutine.
5 GSD File
GSD file is a text file for identifying PROFIBUS DP device (master or slave). GSD file contains required
information on configuring a PROFIBUS DP slave on a standard PROFIBUS DP master, including informati on
on the supplier, baud rates supported, I/O sign als available. GSD file is the ba sic tool recording the p arameters

of the master. When DVPPF02-H2 is used as PROFI BUS DP slave, you have to add the GSD file of
DVPPF02-H2 into the configuration tool of PROFIBUS DP master. The GSD file of DVPPF02-H2 is available
for download at Delta’s website http://www.delta.com.tw/

About data mapping:
The I Address of the master (starting from the first address of slot 0 ~ slot 4) corresponds to CR from CR#3
of the slave. The Q Address (starting from the first address of slot 0 ~ slot 4) corresponds to CR from
CR#103. The I/Q Address in every slot increases by 2, in which the I Address i s indicated as PIW and Q
Address as PQW. The CR corresponds to PIW and PQW increases by 1. According to the table above, the
data in PQW256 ~ PQW270 are transmitted automatically to CR#103 ~ CR#110, and the data in CR#3 ~
CR#8 are transmitted automatically to PIW256 ~ PIW266 through PROFIBUS DP bus. The above mapping
relation will be formed automatically after the parameter is configured.

z When DVP-EH2 PLC MPU is running and M1000 is On, DVP-EH2 will move the 8 words of data
transmitted from PROFIBUS DP master to CR#103 ~ CR#110 to D10 ~ D17 through PROFIBUS
DP bus. When M0 = On, DVP-EH2 will write the contents in D20 ~ D25 into CR#3 ~ CR#8.
DVPPF02-H2 will transmit these data to PROFIBUS DP master through PROFIBUS DP bus.
z PROFIBUS DP bus completes the data transmission between the master and DVPPF02-H2.
DFROM/DTO instruction however completes the reading/writing of CR data in DVPPF02-H2 by
DVP-EH2.
z Make sure you use DFROM/DTO instruction instead of FROM/TO instruction to deal with the CR
data in DVPPF02-H2 by DVP-EH2.
