3.1 Cable types

The cable types are specified according to IEC 61158-2. Shielded cables offer the advantage of malfunction-free operation with adequate protection against electromagnetic influences, and make it possible to employ the full performance of the Foundation Fieldbus system.

Core cross-section	0.8 mm2 or	0.32 mm2 or	0.13 mm2 or	1.25 mm2 or
	AWG 18	AWG 22	AWG 26	AWG 16
Cable type	A	B	C	D
	twisted pair,	individual or	multiple twisted	multiple non-
	individually	multiple twisted	pairs, without	twisted cables,
	shielded	pairs with overall	shielding	without shielding
		shield
Max. length	1900 m / 6200 ft	1200 m / 3900 ft	400 m / 1300 ft	200 m / 650 ft
incl. branch line

In non-hazardous locations, a maximum of 32 field devices can be connected to the network. For more data, refer to the table that follows.

Number of devices	Cable lengths for number of devices per branch line
	1 device	2 devices	3 devices	4 devices
25...32	1 m / 3.3 ft	1 m / 3.3 ft	1 m / 3.3 ft	1 m / 3.3 ft
19...24	30 m / 100 ft	1 m / 3.3 ft	1 m / 3.3 ft	1 m / 3.3 ft
15...18	60 m / 200 ft	30 m / 100 ft	1 m / 3.3 ft	1 m / 3.3 ft
13...14	90 m / 300 ft	60 m / 200 ft	30 m / 100 ft	1 m / 3.3 ft
1..12	120 m / 400 ft	90 m / 300 ft	60 m / 200 ft	30 m / 100 ft

All bus segments must be fitted with a terminator at both ends.

3.2Shielding and grounding

•For optimum electromagnetic compatibility of systems it is extremely important that the system components, and particularly the bus cables connecting the components, are shielded and that such shields - if possible - form an unbroken cover.

•Hence, it follows that, for use in non-hazardous duty systems, the cable shield should be grounded as often as possible.

•In Ex systems an adequate equipotential bonding in the hazardous and non-hazardous location along the entire Fieldbus installation is strongly recommended. Multiple grounding of the shield is of advantage.

•In explosion-proof systems the shielding must at least be connected at one end of the cable.

•NAMUR NE 21 compliance is given, provided the above recommended cable types are used.

INFORMATION!

The use of twisted and shielded cables is strongly recommended, otherwise EMC protection of the signal converter cannot be assured.

3.3 Electrical connection of FOUNDATION Fieldbus

INFORMATION!

The wiring between the device and the FOUNDATION Fieldbus cable is independant of polarity. The signal converter FOUNDATION Fieldbus interface will operate only if the additional power supply for the device is connected/available.

For a detailed description of the electrical connections please refer to the standard signal converter handbook.

3.4 Topology of FF networks

An example of mixed topology of FF networks is shown in the following example.

Connection is best made via short branch cables and T connectors. This connection type makes it possible to connect and disconnect the devices without interrupting the bus or the communication.

4.2 Description of the FF block system

The Foundation Fieldbus is a Local Area Network (LAN) for connecting field devices like sensors and actuators. One of the main benefits of Foundation Fieldbus is line saving in comparison to the traditional 4...20 mA technology.

The different device functions are implemented in a block-based scheme within a user application. In this block scheme, a distinction is made between the Resource Block, Transducer Block and Function Block.
