Molex Introduces SST Universal Modbus Modules for CompactLogix Controllers

January 26, 2016 By Lisa Eitel Leave a Comment

Molex, LLC has introduced two new seamlessly integrated Modbus modules for Rockwell Automation CompactLogix controllers. The two Universal Modbus modules connect CompactLogix controllers to any Modbus/TCP or Modbus serial networks from the same module, even at the same time.

Modbus CPX Modules“Molex is focused on putting best-in-class industrial solutions in the hands of our customers,” said Ken Prentice, product specialist, Molex.

“Our expanding portfolio of Modbus module solutions underscores the expertise and commitment of Molex to our SST CompactLogix solutions, while providing a cost-effective price-point.”

The first module is a Standard version (SST-ERS2-CPX-S) and the second is a Plus version (SST-ESR2-CPX-P), which supports extended addressing to 30,000 I/O words and up to 256 Modbus commands per port. The modules have two independent RS232/RS422/RS485 serial ports that support ASCII and RTU formats. The ports can be configured to operate as Modbus masters and/or Modbus slaves.

The software automatically determines if the Modbus message is RS232/RS422/RS485, eliminating the problem of improperly setting dip-switches. Also, each module has one Ethernet port (independent of the CompactLogix Ethernet port) that executes Modbus TCP protocol.

Alternatively, with these modules the Ethernet port can be used as another means for configuration and troubleshooting. This provides additional flexibility for configuration as well as troubleshooting, allowing options for using either a backplane connection or the front of the module. With 2500V electrical isolation between all three Modbus ports, as well as between the ports and backplane, the new Universal Modbus modules provide superior network reliability and smart functionality.

The Molex SST CompactLogix modules can be used in many industrial applications, such as water/wastewater, oil and gas, and chemical/petrochemical.
