Molex has announced its SST PB3-CPX modules to connect Rockwell Automation CompactLogix L2, L3 and L4 controllers to PROFIBUS DP-V0 and DP-V1 networks. According to the company, the modules allow high-performance, low-cost solutions for industrial automation applications and are compatible with Master DP-V0 Class-1; Master DP-V1 Class-1 and Class-2; and Slave DP-V0 protocols.

SST PB3-CPX Master/Slave Modules can be configured as PROFIBUS Master, Slave or Master/Slave, delivering a flexible design that reduces inventory and spares. The modules are easy to spec in and offer up to 1,984 input bytes and 1,968 output bytes per master, making them suitable for large PROFIBUS networks, noted Molex.

All three variants accommodate low-cost Ethernet cable and feature a 10/100Mb Ethernet port that enables fast downloads as well as remote connections and monitoring. The modules provide backplane or front-module configuration options. A MicroSD card slot, with an 8Gbyte MicroSD card included, facilitates easy module swap-out. Offering a mean time between failure (MTBF) of 181 years, the modules provide reliable, trouble-free usage. SST PROFIBUS modules feature 1kV electrical isolation between ports, ensuring a robust, reliable network with high immunity to electrical noise. The modules are appropriate in applications that include material handling, packaging, agro-food, mining and water/wastewater.

SST PB3M-CPX Master Modules feature software configured as PROFIBUS Master, which delivers a flexible design, Molex noted. The master module supports 1,984 input bytes and 1,968 output bytes. SST PB3S-CPX Slave Modules feature up to 244 input bytes and 244 output bytes per slave. Software configured as slave requires no ladder logic.
