Communication between controllers and intelligent sensors made easy
In 2005 Panasonic, known for sensors at that time under the brand name SUNX, introduced the FX-300 series fiber-optic sensors. These sensors were the first worldwide to provide a master-slave function via optical interfaces between sensors. Each sensor could thus act as master or slave. Using these interfaces it was possible to copy settings such as threshold values, response times, NO/NC states, etc. from one sensor to the others. This not only saved time but also ensured reliability for applications that required several sensors. For these reasons, high-precision laser and pressure sensors soon began taking advantage of optical interfaces, too.
We continued to pursue this philosophy when designing the SCGUxx series units, i.e. units were developed that provided an interface between bus and sensor. Though RS485 is still the most prevalent interface in use, units for CC-Link, DeviceNet and EtherCAT have been introduced as solutions for open networks. More units are planned!
Advantages at a glance:
• Easy monitoring of digital values and statuses
• Setting values can be saved when performing maintenance
• One communication unit can connect up to 16 fiber-optic, laser and pressure sensors
• Connector reduces wiring and makes mounting easy
• Sensors can be configured from a central station
