 DISCONTINUED IEC 60870-5-104 Server to
DH-485 Gateway
IEC 60870-5-104 Server to DH-485 Gateway
The 104S-DH485 modules are the ideal solution for the
many applications where IEC 104 Server connectivity
can be used to integrate a DH-485 device into a system.
The IEC60870-5-104 Server gateway is a powerful
module designed with Server support, enabling easy
connection to an IEC 104 master device. In combination
with the DH-485 device support, the module provides a
very powerful interface to the many DH-485 devices
which are in use in the industrial marketplace today.
Applications for the module are found in most industries,
especially Manufacturing, Oil and Gas, Electrical Power
and Food Processing.

The 104S module accepts commands from an attached master unit
on the network and generates unsolicited messages.
The DH-485 protocol driver supports the Master and the Slave
modes of the protocol on each port, providing powerful data transfer
capability with Rockwell Automation PLCs and HMIs. All DH-485
ports are individually configurable. User configurable data mapping
make the interface an easy to use and powerful data transfer tool.
IEC 60870-5-104 Server
Operating in the Server mode, the protocol driver accepts commands
from an IEC-60870-5-104 Client to read/write data stored in the module's
internal registers.
The 104S module acts as an input/output module between the
IEC 60870-5-104 Ethernet network and many of the other serial and
network protocols, as well as several proprietary interfaces.
General specifications include:
User-definable module memory usage
Protocol implementation conforms to the IEC 60870-5-104
specification with fully configurable parameters
• SNTP (Simple Network Time Protocol) timestamping for detailed
logging of data transactions.
The 104S module accepts commands from an attached master unit
on the network and generates unsolicited messages. These last sets
of messages are either spontaneous or cyclic. Data transferred to the
host is derived from the module's internal database. The remote
master device can control data in the database and hence the
devices connected using the other protocol in the module using
standard control messages supported in the protocol. The remote
master device uses the fully-configured databases in the module to
control outputs and monitor inputs.

The ProLinx IEC60870-5-104 Server to DH-485 Gateway creates a
powerful connection between devices on an IEC 104 Server network
and a DH-485 device. This stand-alone DIN-rail mounted protocol
gateway provides one DH-485 configurable serial port and one
Ethernet port.

Configuration Serial Port
The DH-485 protocol in its native form is a peer to peer token
passing network. The ProLinx DH-485 driver accesses the network
functioning either as a Master or as a Slave.
Ethernet Port (Ethernet
modules only)
Application Serial Ports
Serial Port Isolation
DH-485 Slave Mode
In Slave mode, the module accepts commands from one or more
Masters to read/write data stored in the module's internal data
memory. In this mode, the ProLinx unit is answering DH-485
commands and has the appearance of an SLC processor to the
DH-485 Master Mode
In Master mode, the ProLinx DH-485 driver will actively gather data
from other devices on the network, controlling the read/write data
transfer between the gateway and other DH-485 devices, such as
SLC processors. Data transfer can be initiated and executed with the
other devices without any ladder logic being required in the Rockwell
Automation slave hardware.
DH485 Functioning as a Master
Command List
Up to 100 command per master port, each
fully configurable for function, slave
address, register to/from addressing and
word/bit count
Polling of command list
User configurable polling of commands,
including disabled, continuous and on
change of data (write only)
General Specifications
The ProLinx Communication Modules provide connectivity for two or
more dissimilar network types. The modules, encased in sturdy
extruded aluminum, are stand-alone DIN-rail mounted protocol
gateways, providing communication between many of the most
widely used protocols in industrial automation today.
