March 11, 2013 - WAGO releases the IP67 SPEEDWAY 767-1311 Fieldbus Coupler, which links the fieldbus level to Sercos V1.2 real-time Ethernet fieldbus system. Supporting all Sercos cycle times, WAGO’s high-performance coupler integrates into a Sercos system via Standardized Sercos Profiles and Device Description (SDDML). The machine-mount coupler features 10µs high-speed synchronization for harsh-environment motion control applications that may not have the resources for enclosures.
SPEEDWAY Sercos coupler’s eight high-speed digital inputs capture binary signals from switches and sensors with a 10µs (microseconds) scanning cycle — compatible with 31.25µs Sercos cycles. Because the coupler connects to a wide range of WAGO-I/O-SYSTEM modules, SPEEDWAY can support “hard” real-time applications with I/O cycles of a mere 250µs. The coupler is extendable up to 64 modules, which can be installed away from the Sercos coupler for system expansion up to 200m.
This enables digital and analog I/O modules to be installed directly next to sensors and actuators. 767-1311 determines station structure upon install, generating the process image for configured I/O — even for mixed (analog, digital and specialty modules) stations. Parameter setting via FDT/DTM (including diagnostics and simulation) simplifies integration. Dual, integrated Ethernet ports create both line and ring topologies without additional components.
Supporting Auto MDI/MDI-X, the ports detect transmission direction — patch and crossover cables can be used. 767-1311 carries UL 508.
