IBA ibaFOB-4i-S / -io-S fiber optic communication cards

Introduction

The boards ibaFOB-io-PCI, ibaFOB-io-S, ibaFOB-4i-PCI, ibaFOB-4i-S, ibaFOB-4o

and ibaFOB-OF-Link are fiber optic communication cards which are used to connect

a stan-dard PC to the iba peripheral devices such as ibaPADUs, ibaNet750-BM

devices and ibaLink signal modules (SM).

As far as the following text does not refer to a particular card, the boards are

referred to as ibaFOB boards.

The unique peripheral I/O concept based on the ibaFOB boards, features

characteristics otherwise unknown on standardized field buses such as:

 Full deterministic transmission profiles for all fiber optic buses and connected

devices (1ms).

 Internal and/or external synchronization on the bus, even for more than one

bus with programmable cycle times between 1.0 and 9.9 ms in steps of 100 μs.

 Deviation less than 2 μs between several busses (external synchronization)

 The iba fiber optic transmission standard integrates not only A/D converters

(ibaPADU) but a huge variety of PLC interfaces and hence allows the realization

of heterogene-ous measuring and I/O topologies.

Mitsubishi ST Series Key Features

Key Features:

• Network Head Stations for CC-Link and PROFIBUS/DP

• Mix-and-match I/O types: Digital and Analog

• I/O-count expansion as low as 2-point up to 16-point; 63 slices max

Digital I/O Modules

The ST Series Digital Input/Output modules come in various sizes and

capacities, with counts as low as 2 points and as high as 16 points.

These modules can be assembled in any order and mixed with analog

I/O modules as well. Each I/O module requires a corresponding base

module, which will be individually keyed to that type of I/O module 

after the first use. This prevents spare modules to be placed in incorrect

position during maintenance such as Online Module Change.

ICS TRIPLEX Front Panel Unit (FPU)


Front Panel Unit (FPU)

The Front Panel Unit (FPU) contains the necessary connectors, switches,

logic, and LED indicators for the Front Panel. For every type of Trusted I/O

Module, the FPU contains the Slice Healthy, Active/Standby, the Educated

LED indicators, and the Module removal switches. Additional bicolor LEDs

provide status indication for the individual I/O signals. Serial data interfaces

connect the FPU to each of the HIU slices to control the LED status indicators

and monitor the Module removal switches.

ICS TRIPLEX Host Interface Unit (HIU)

Host Interface Unit (HIU)

The HIU is the point of access to the Inter-Module Bus (IMB) for the Module.

It also provides power distribution and local programmable processing

power. The HIU is the only section of the I/O Module to directly connect to the

IMB Backplane. The HIU is common to most high integrity I/O types and has

type dependent and product range common functions. Each HIU contains

three independent slices, commonly referred to as A, B, and C.

All interconnections between the three slices incorporate isolation to help

prevent any fault interaction between the slices. Each slice is considered a

Fault Containment Region (FCR), as a fault on one slice has no effect on the

operation of the other slices.

The HIU provides the following services common to the Modules in the

family:

• High-Speed Fault Tolerant Communications with the TMR Processor

via the IMB interface.

• FCR Interconnect Bus between slices to vote incoming IMB data and

distribute outgoing I/O Module data to the IMB.

• Galvanically isolated serial data interface to the FIU slices.

• Redundant power sharing of dual 24 Vdc chassis supply voltage and

power regulation for logic power to HIU circuitry.

• Magnetically isolated power to the FIU slices.

• Serial data interface to the FPU for Module status LEDs.

• SmartSlot link between Active and Standby Modules for coordination

during Module replacement.

• Digital Signal Processing to perform local data reduction and

self-diagnostics.

• Local memory resources for storing Module operation, configuration,

and field I/O data.

• Onboard housekeeping, which monitors reference voltages, current

consumption and board temperature.

ICS TRIPLEX Field Interface Unit (FIU)

Field Interface Unit (FIU)

The Field Interface Unit (FIU) is the section of the Module that contains the

specific circuits necessary to interface to the particular types of field I/O

signals. Each Module has three FIUs, one per slice. For the TMR 24 Vdc Digital

Output Module, the FIU contains one stage of the output switch structure,

and sigma-delta (ΣΔ) output circuit for each of the 40 field outputs. Two

additional ΣΔ circuits provide optional monitoring of the external field I/O

supply voltage.

The FIU receives isolated power from the HIU for logic. The FIU provides

additional power conditioning for the operational voltages required by the

FIU circuitry. An isolated 6.25 Mbit/sec serial link connects each FIU to one of

the HIU slices.

The FIU also measures a range of onboard “housekeeping” signals that assist

in monitoring the performance and operating conditions of the Module.

These signals include power supply voltages, current consumption, onboard

reference voltages and board temperature.
