Modbus TCP/IP to Siemens
3964R Protocol Gateway
The ProLinx® Modbus TCP/IP to Siemens 3964R Gateway allows point-to-point communication
between a Modbus TCP/IP Ethernet network and 3964R serial communication partners.
The Modbus TCP/IP protocol driver supports Schneider Electric processors as well most other devices
that use Modbus TCP/IP for communicating over Ethernet networks. The gateway offers both Client
(Master) and Server (Slave) configurations that use standard Ethernet TCP/IP connections and
recognize both Modbus TCP/IP MBAP and Encapsulated Modbus messages. The Modbus TCP/IP
implementation on this gateway has been specially developed to provide tight integration with 3964R
protocol requirements.
The 3964R protocol was designed by Siemens for bi-directional data communication. It provides a
point-to-point, serial interface connection that supports assigning high-priority or low-priority read and
write access to each communication partner. This reduces initialization errors and improves data
messages, increasing its versatility and range of possible applications.

General Specifications
ProLinx® Communication Gateways provide connectivity for two or more dissimilar
network types. The gateways, encased in sturdy extruded aluminum, are stand-alone
DIN-rail-mounted solutions that provide data transfer between many of today’s most
widely used industrial automation.
Modbus TCP/IP
ProSoft's Modbus TCP/IP implementation uses the gateway's shared internal memory
database for data transfer. Sharing the memory database with another protocol driver
allows the gateway to transfer data between Modbus TCP/IP devices and other devices
on other networks.
Configurable floating point data movement is supported, including support for Enron or
Daniel floating point applications.
Modbus TCP/IP Server (Slave)
The server driver accepts incoming connections on Service Port 502 for clients using
Modbus TCP/IP MBAP messages and from clients on Service Port 2000 (or other
Service Ports) for clients using Encapsulated Modbus messages..
Supports five independent server connections for Service Port 502 (MBAP)
Supports five independent server connections for Service Port 2000 (Encapsulated)
The Modbus TCP/IP implementation in this gateway has been specially designated
to meet the unique requirements of the 3964R protocol. This provides a more tightly
integrated solution for data transfer between the two protocols.
Modbus data types overlap in the gateway's memory database, so the same data
can be conveniently read or written as bit-level or register-level data.
Modbus TCP/IP Client (Master)
Actively reads data from and writes data to Modbus TCP/IP devices, using MBAP
or Encapsulated Modbus message formats
Offers one client connection with up to 100 commands to talk to multiple severs
Status Data
Error codes, counters, and port status available
Supported baud rates: 600 through 19200 are typical; up to 115200 is possible
Supported protocols: 3964 with RK512, 3964 without RK512
Priority setting to define the behavior of the protocol in case of an initialization
Offers four independently configurable serial ports. Each port can communicate
using 3964R protocol with or without RK512 formatting. Each port can be set to use
an RS-232 or RS-422 serial signal interface. The ports operate independently from
each other and each port is assigned its own space in the gateway's user memory
When using S3964R without RK512 communications mode, Port 0, Port 1, Port 2,
and Port 3 can initiate or receive DB-SEND instructions.
RK512 mode on Port 0, Port 1, Port 2, and Port 3 allow evaluation of RK512 header
information: DB data block, DW data word, Coordination Byte 9, and CPU
Coordination Byte 10.
When using S3964R without RK512 communications mode, Port 0, Port 1, Port 2,
and Port 3 can send or receive standard communication telegrams (message
In either mode, 512 bytes is the maximum amount of data transferred per data
transfer operation
Data byte order can be swapped to support different device-specific word formats
Communication activity indications and diagnostic information are available through
LEDs and acknowledgment telegrams.
