DVP-FEN01 Ethernet Communication Card Operation Manual
Thanks for using the communication card DVP-FEN01. To ensure that the product is correctly installed and
operated, users need to read the operation manual carefully before they use DVP-FEN01.
DVP-FEN01 is an Ethernet communication card. It supports a standard Modbus TCP communication protocol.
It can pass the Modbus TCP data received to the PLC to which it is connected. Besides, the PLC to which it is
connected can send Modbus TCP data to other devices on Ethernet. It supports Delta PLC software. Users can
use Ethernet or a RS-232 cable to upload the program in a PLC/download a program to a PLC and monitor a
program through DVP-FEN01.
The operation manual provides functional specifications, and introduces installation, basic operation and
setting, and communication protocols.
The product is the communication card used used with a PLC. If users want to use this product, they have
to install it in a DVP-EH3 series PLC. (It only supports a DVP-EH3 series PLCs whose firmware version is
1.12 or above.)
Please refer to an instruciton sheet for more inforation about the environment in which a PLC can be
installed and points for attention.
Please check the wiring of a PLC before the PLC is powered. Do not touch any terminal when a PLC is
powered.
In order to prevent the product from being damaged, or prevent staff from being hurt, users need to read
the operation manual carefully, and follow the instructions in the manual.
1.1 Functions
It provides DVP-EH3 series PLCs with an Ethernet communication function.
It is equipped with an Ethernet port and an RS-232 port.
The Ethernet port automatically detects the transmission speed of 10/100 Mbps.
The Ethernet protocols it supports are ARP, IP, TCP, UDP, DHCP, and Modbus TCP.
There are eight Modbus TCP clients (for sending packets), and four Modbus TCP servers (for receiving
packets).
It supports four IP filters. The IP addresses which can not be accessed can be filtered out.
Users can use Ethernet or a RS-232 cable to upload the program in a PLC/download a program to a PLC
and monitor a program through DVP-FEN01. The Modbus ASCII communication format that the RS-232
port on a DVP-EH3 series PLC supports is “19200, 8, N, 1”.
