Profibus connector with built-in troubleshooting features
May 2003
Enclosures, Cabling & Connectors
The EasyConn bus connector from profichip provides all test functions that speed up implementation and troubleshooting. Four LEDs, which are visible from both sides, indicate bus- and device-status: the yellow LED shows the voltage supply of the device (PWR), the green LED the bus-activity (TxD); another yellow LED informs whether the termination is switched OFF or ON (Term). The red LED indicates whether there is a wrong termination resistance or false surge impedance that influences the bus transfer (ERR). The integrated EasyConn Controller works with a baud rate of up to 12 Mbaud. Even at this rate the power consumption is very low, so that the Profibus-participants are strained at the minimum. The connector with vertical cable run provides easy access to the integrated PU/diagnosis socket; no additional hub is required. The full metal case ensures high noise immunity. The plug with slide switches activates the switchable termination resistances, which are accessible from both sides. In this way, testing of the Profibus communication can be executed without removing plugs or cable, the cable ducts are equipped with transparent cover so the correct correlation of the bus cords is visible. Also, under field conditions, easy connection of stiff or flexible bus cable is supported by integrated cutting-clamps. All parts of the plug are designed as screw saving.
