	IFC 100

3.1 Installation in hazardous area and bus cable

We recommend that a Foundation Fieldbus network in the hazardous area should be projected in accordance with PTB's FISCO model. The FISCO model is based on the following conditions:

•All electrical components which should be connected to the bus must be approved according to the FISCO model (even the termination).

•The maximum cable length should not exceed 1000 m / 3280.8 ft.

•The approved input values of the field devices (U0, I0, P0) comply to the output values of the power supply (e.g. segment coupler) according to: U0 ≤ Ui; I0 ≤ Ii; P0 ≤ Pi.

•The values of the cable must be within the following ranges: R' = 15…150 Ω/km; L' = 0.4…1 mH/km; C' = 45…200 nF/km

equivalent to

R' = 24…240 Ω/mile; L' = 0.65…1.6 mH/mile; C' = 72…320 nF/mile

Other limitations for the cable than the FISCO limitations are not existent. Nevertheless, a twisted pair and shielded cable is strongly recommended.

Example: a good quality cable could have the following data: 44 Ω/km = 70.4 Ω/mile; <90 nF/km

=<144 nF/mile; attenuation at 39 kHz: <3 dB/km = <4.9 dB/mile; impedance 100 Ω at 31.25 kHz.

3.2Grounding of measuring sensor

•The measuring sensor must be properly connected to ground.

•The grounding cable should not transmit any interference voltages.

•Do not use the grounding cable to connect more than one device to ground.

•In hazardous areas, grounding is used at the same time for equipotential bonding.

•The sensors are connected to ground by means of a functional grounding conductor FE.

DANGER!

Special grounding instructions are contained in the "Ex supplement", which are only supplied together with hazardous-duty equipment.

INFORMATION!

Special grounding instructions for the various measuring sensors are contained in the separate installation instructions for the measuring sensors. These instructions also contain detailed descriptions on how to use grounding rings and how to install the measuring sensors in metal or plastic pipes or in pipes which are coated on the inside.

3.3 Foundation Fieldbus electrical connection

The output and input groups are electrically isolated from each other and from all other input and output circuits.

DANGER!

The signal converter must be properly grounded to avoid personnel shock hazard. All directions, operating data and connection diagrams do not apply to devices used in hazardous areas; in such cases, read the special Ex instructions without fail!

3.4 Cable types

IFC 100

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 areas the maximum number of field devices is limited to 32. For detailed information refer to the following table.

In non-hazardous areas the ignition protection class of the devices and the limited electric power available limit the number of field devices to 4.

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.

3.5Shielding 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.

INFORMATION!

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

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.

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.

UPDATE_STATE		R	A discrete enumeration which gives an indication of whether	Uninitialized
Update State			the alert has been reported.
			Setting:
			Uninitialized / Reported / Not reported
TIME_STAMP		R	The time when evaluation of the block was started and a	Uninitialized
Time Stamp			change in alarm/event state was detected that is unreported.
			The time stamp value will be maintained constant until alert
			confirmation has been received - even if another change of
			state occurs.
			Setting:
			MM / DD / YY (Month / Day / Year)
			HH:MM:SS (Hour:Minute:Second)
STATIC_REVISION		R	The static revision of the block whose static parameter was	0
Static Revision			changed and is being reported. It is possible for the present
			value of static revision to be greater than this because static
			can be changed at any time.
			Setting:
			0…65535
RELATIVE_INDEX		R	The OD index of the static parameter whose change caused	0
Relative Index			this alert, minus the FB starting index. If the update event was
			caused by a write to multiple parameters at the same time,
			then this attribute will be zero.
			Setting:
			0…65535
WRITE_ALM			This alert is generated if the write lock parameter is cleared.	-
Write Alarm
UNACKNOWLEDGED		R/W	A discrete enumeration which is set to "Unacknowledged"	Uninitialized
Unacknowledged			when an alarm occurs, and set to "Acknowledged" by a write
			from a human interface device or other entity which can
			acknowledge that the alarm/event has been noticed.
			Setting:
			Uninitialized / Acknowledged / Unacknowledged
ALARM_STATE		R	A discrete enumeration which gives an indication of whether	Uninitialized
Alarm State			the alert is active and whether it has been reported.
			Setting:
			Uninitialized / Clear - reported / Clear - not reported /
			Active - reported / Active - not reported
TIME_STAMP		R	The time when evaluation of the block was started and a	Uninitialized
Time Stamp			change in alarm/event state was detected that is unreported.
			The time stamp value will be maintained constant until alert
			confirmation has been received - even if another change of
			state occurs.
			Setting:
			MM / DD / YY (Month / Day / Year)
			HH:MM:SS (Hour:Minute:Second)
Sub_Code		R	An enumeration specifying the cause of the alert to be	Other
Subcode			reported.
			Setting:
			Other / Block Configuration / Link Configuration / Simulation
			Active / Local Override / Device Fault State / Device
			Maintenance / Input Failure / Output Failure / Memory
			Failure / Lost Static Data / Lost NV Data / Readback Check /
			Maintenance Needed / Power Up / Out Of Service
VALUE		R	The value of the associated parameter at the time the alert	State 0
Discrete Value			was detected.
			Setting:
			Discrete State 0...16
