SST™ Communication Module from Molex Streamlines Connection of Allen-Bradley
ControlLogix* to Siemens Industrial Ethernet
Updated communication module firmware delivers ease-of-use and more
versatility in industrial Ethernet connectivity
LISLE, Ill. -- November 16, 2012
Molex Incorporated showcased a new firmware release of the SST™ Ethernet
communication module at Automation Fair 2012 in Philadelphia, PA. The firmware
update supports the Siemens Industrial Ethernet protocol to connect
ControlLogix PLCs to Siemens SIMATIC† controllers (S5, S7-1200, S7-200, S7-300
and S7-400), SIMOTION† motion controllers, RFID and barcode readers, SINAMICS†
variable frequency drives and SINUMERIK† CNC systems.
“SST communication modules are the fast and easy way to connect Modbus TCP and
Siemens Industrial Ethernet to Allen-Bradley ^ ControlLogix controllers,”
states George Kairys, product manager, Molex. “When the ControlLogix processor
is combined with an SST communications module, users receive a reliable and
powerful communication network providing time and cost savings resulting from
The firmware update enables users to simultaneously manage communication in
client and server modes to allow the module to read/write data and receive
unsolicited data from Siemens controllers. The protocol supports various
process data types including: M, DB, A, E, T, Z with support up to 127 TCP
connections. Molex configuration software allows easy CIP path generation for
bridged or routed connections to remote SST Ethernet communication modules.
Regardless of the location of the SST module in the network architecture,
users can connect to the module remotely to a local or a remote chassis.
Additionally, the SST module can be configured and diagnosed via Ethernet
using Rockwell Automation’s EtherNet/IP modules (1756-ENBT).
SST communication module firmware supports 32- and 64-bit platforms in Windows
7. Enabling rapid implementation of control applications, SST communication
modules include an add-on profile to interface seamlessly into the RSLogix*
5000 programming environment and directly share I/O process data with Logix
processor memory, without writing any ladder logic or using PLC memory or
increasing PLC scan time.
“Utilization of flexible chipset technology provides a fully software
configurable module—no need to set specific jumpers for specific physical
layer configurations, no jumpers to lose, no jumpers to misconnect and no
additional manuals required,” adds Kairys.
The SST Ethernet communication module includes an Ethernet port and two Serial
ports for simultaneously running protocols, with the module serving as a
standalone gateway between communication ports. So, users can read data from a
Serial Modbus slave and write to a Siemens S7-300 PLC via the industrial
Ethernet port. This feature is enabled by the module’s internal data base of
32,000 word registers and 32,000 bits that can simultaneously share and
exchange data with the ControlLogix processor.
SST communication modules from Molex are designed for multiple industries,
including food processing, water and wastewater, oil and gas, mining,
petrochemical and manufacturing. For more information on Brad® solutions for
