PHOENIX CONTACT is the international leader in the field of INTERBUS technology. For more than 10 years their range of controller boards and installation systems has grown, providing the optimum system solution for every application. In the field of control technology PHOENIX CONTACT offers, alongside controller boards for PC-based and VMEbus systems, a wide range of controller boards for traditional control systems (PLCs). This range of products, marketed under the banner "Controller boards for PLCs", offers a common access to peripherals for all internationally available control systems.

INTERBUS controller boards offer users of traditional control systems (PLCs) the opportunity to build identical series production lines, carry out the I/O wiring with INTERBUS and connect any control system. This means that it is simple to change the configured device level by changing the system/machine from one control system to another.

There are many obvious advantages of INTERBUS controller boards:

	Control technology can be changed as desired
	Software standards can be easily incorporated
	One-off engineering costs at the device level
	A pool of expertise can be concentrated on one fieldbus system, which increases quality at all levels, from system support to the end customer

The huge potential gains in terms of cost when INTERBUS is used are often the decisive factor for system and machine designers, as the resulting savings can be passed on directly to the end customers.

The following traditional control systems are currently supported:

	Siemens
	Allen-Bradley
	GE-Fanuc
	Klöckner-Moeller
	Cegelec
	Group Schneider
	Bosch
	Mitsubishi
	Modicon
