Networking via GSM or GPRS


We use powerful, modern technology to exchange data between controllers.

Ethernet networking
HANNING & KAHL deploys modern networking on the basis of industrial Ethernet. In particular when planning and designing depot controllers and wayside equipment, this technology facilitates maximum efficiency and flexibility. Connection to higher-ranking computer systems (Operate & Observe, control systems, depot management systems) is thus state of the art.

Controller networks
Local controllers are networked via LAN. A standard bus system guarantees safe communication and easy extension. Copper or fibre-optic cables can be used depending on customer requirements. Ring, star or redundant structures arepossible.

Telephone lines, GSM or GPR
HANNING & KAHL uses networking via existing communication channels such as telephone lines, GSM or GPRS to read out event recorders remotely, relate malfunctions and transmit FADIS data to a central control room. Advantage: Access via existing communication channels means cable investments are not necessary. Simple and at low cost.
