ABB 07KT93 GJR5251300R171 procontic CS 31 controller Central Unit with ARCnet
Description:
The central unit 07 KT 93 works either as
bus master in the decentralized automation system ABB Procontic CS31 or as
slave (remote processor) in the decentralized automation system ABB Procontic CS31 or as 
stand–alone central unit.
The device has a 24 V DC power supply voltage. It is provided with an additional interface for connecting communication modules (e.g. 07 KP 90).
The central unit 07 KT 93 R171 is equipped with an integrated ARCnet coupler (and an ARCnet interface).
The ARCnet coupler is integrated in the central unit 07 KT 93 R171. The DIL switch for setting the ARCnet address is accessible through the cutout of the external networking interface.
The ARCnet coupler is supplied from the internal 24 V DC power supply.
The data packages are read from the ARCnet controller interrupt-controlled. The interrupt routine stores the data package in the storage buffer. The APOLL block serves for the sending direction. It transfers data packages from the storage buffer to the
ARCnet controller for sending them off.
