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.

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

3.2 Shielding 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.

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.

4.5 Analog Input Block (AI 1...6)

The following tables list the Analog Input Block parameters in alphabetical order.

It describes characteristics of the measurement values obtained from the Transducer Block in a user defined way and to deliver it to the control system. There are also some parameters in the Analog Input Block, that can be configured to get a measurement value quality as desired by the user.

The following tables contain short parameter description, factory settings (Initial Value (IV)) and possible settings.

R This parameter reflects the error status associated with the

hardware or software components associated with a block. It is a bit string, so that multiple errors may be shown.

Setting:

• Other: Non-specific error active

• Block Configuration: Error detected in block configuration

• Link Configuration: Error detected in link configuration

• Simulation Active: Simulation enabled in this block

• Local Override: Output tracking of faultstate active

• Device Fault State: Device faultstate set

• Device Maintenance: Device needs maintenance soon

• Input Failure: Process variable has bad status

• Output Failure: Failure detected in output hardware

• Memory Failure: Memory error detected

• Lost Static Data: Static parameters cannot be recovered

• Lost NV Data: Non-volatile parameters cannot be recovered

• Readback Check: Failure detected in READBACK

• Maintenance Needed: Device NEEDS maintenance NOW

• Power Up: Recovery from power failure

• Out Of Service: Block actual mode is out of service

Mix The actual, target, permitted and normal modes of the block. -

R/W By setting this parameter to an allowed value (one of the value

from permitted modes) user can change the block execution mode. Changing of modes is required to change the access permissions available to various parameters.

Setting: Auto / OOS

R This is the current mode of the block, which may differ from

the target based on operating conditions. Its value is calculated as part of block execution.

Setting: Auto / OOS

R/W Defines the modes which are allowed for an instance in the

block. The permitted mode is configured based on application requirements.

It describes characteristics of the signal converter measurements for forward (positive) and reverse (negative) flow at the same time. Both integrators were intended to totalize the forward flow Integrator 1 (+ Flow Totalizer) on the one hand and the reverse flow Integrator 2 (- Flow Totalizer) on the other. The configuration of these blocks is almost the same, unless stated differently.

Access Description and settings Initial Value

R/W INTEG_OPTS is to be used to specify several integration

options as type of input used in each input, flow direction to be considered in the totalization, status to be considered in the totalization and if the totalization residue shall be used in the next batch after a reset.

The following INTEG_OPTS are possible (see also INTEG_TYPE):

• Input 1 accumulate: IN_1 is used as pulse (otherwise as rate)

• Input 2 accumulate: IN_2 is used as pulse (otherwise as rate)

• Flow forward: only positive net flow will be taken into

account for totalization

• Flow reverse: only negative net flow will be taken into

account for totalization

• Use Uncertain: IN_1 and IN_2 input will be taken into

account even if their states are "Uncertain" (otherwise the value with the last "Good" status will be taken)

• Use BAD Input: IN_1 or IN_2 with "Bad" status will be

interpreted as "Good" (Note: only the status is interpreted as "Good", the value isn't used for totalization, but the good one, i.e. RTOTAL isn't affected with this setting.

• Carry: integration after a reset starts with the init value, but

with the residual after the trip value.

• Add zero if Bad: if one of the input (IN_1 or IN_2) statuses are

"Bad", not the last "Good" value is used for totalization, but zero (0).

• Confirm reset: after a manual reset of totalization, the next

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.

process variable when the block mode is "LO or IMan".

• SP Track retain: Permits the setpoint to track the RCas or

Cas parameter based on the retained target mode when the actual mode of the block is "Man, LO, Man, or Rout".

• Direct acting: Defines the relationship between changes in

PV and changes to output - when direct is selected, an increase in PV results in an increase in the output.

• Track enable: This enables the external tracking function –

when TRK_ENA is 1, the preset value in TRK_VAL is output if TRK_IN_D becomes true.

• Track in manual: This is used only if TRK_ENA is YES (1) -

when the block mode is Man, TRK_IN_D will be acted on only if the TRK_OVMAN control option is set.

• PV for BKCal_Out: The BKCAL_OUT value may be selected

as the working SP or the PV - normally, BKCAL_OUT is the working SP.

• Restrict SP to limits in Cas and RCas: If this option is

selected, the setpoint will be restricted to the setpoint absolute and rate limits in Cas and Rcas modes.
