 Replacement for ibaCom-PCMCIA-F with FO-adapter ibaCom-FO-A

 Suitable for  ExpressCard slots with 34 mm or 54 mm

 Plug and Play

Usage

The card is a member of the ibaFOB-D card family and should be used with mobile

computers for measurement purposes. It can be used for connecting a notebook com

puter with iba field devices like ibaPADU analog-digital converter units, ibaNet750 de

vices, ibaLink system couplings and iba bus monitors.

The ibaFOB-io-ExpressCard with its integrated fiber optic adapter provides for higher

data transmission rates (up to 32 Mbit/s) compared with the former ibaPCMCIA-F card

and shows a performance like the ibaFOB-io-D card.

Considered this, a measurement with mobile computers can be of the same quality le

vel like with stationary systems.

ibaPDA-V6. version 6.24 or higher is required for operation of this card.

Communication protocols

All current and former ibaNet communication protocols are supported. Thus, data from

an old ibaPADU device (S/N < 1000) as well as from an ibaPADU-S-IT of the new gen

eration can be processed by this card.

Furthermore, the ibaNet protocol 5 Mbit/s for fast data acquisition (25 kHz) over de

vices ibaPADU-8-ICP, ibaPADU-8-M or -16-M is supported.

The valid ibaNet protocol of the fiber optic input data stream is detected automatically

by the card. The 32Mbit Flex protocol is supported with firmware version V2.00 (build

172 (C2)) or higher.

Fast data processing with reduced CPU load

Due to the DMA technology (DMA = Direct Memory Access) measured data are written

directly into the computer’s memory which is used by the software application for read

ing the data. It is a significant relief for the CPU load while data traffic is boosted.

iba field devices

Following, you‘ll find a listing of some iba field devices which can be connected to the

ibaFOB-io-ExpressCard:

 ibaPADU-8. -16. -32

 ibaPADU-8-ICP, -8-M, -16-M

 ibaPADU-S-IT

 ibaDIG-40

 ibaBM-DPM-S, -S-64 (Profibus DP)

 ibaBM-eCAT

 ibaBM-SiLink

 ibaBM-SLM (SIMOLINK)

 ibaBM-DDCS (DDCS Drive Bus)

 ibaBM-COL-8i-o

The new cards features are:

 Full Plug&Play functionality.

 Three different data transmission rates per optical link:

3.3 Mbit/s, 5 Mbit/s and 32 Mbit/s

The 2 MBit data transfer to the old ibaPADU-16. – 32 devices is not supported.

(All ibaPADU-16 and -32 with serial number 999 and below use 2 Mbit data

transfer.)

 Three modes of operation on each fiber optic link:

 F-mode, for data acquisition and output up to 1 kHz (1 ms cycle) with 3.3 Mbit/s

 M-mode, for data acquisition up to 25 kHz (40 μs cycle) with 5 Mbit/s

 X-mode, for data acquisition up to 20 kHz (50 μs cycle) with 32 Mbit/s

 Enhanced card diagnostics and card information in ibaPDA-V6

The ibaFOB I/O Concept

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

otherwise unknown on standardized field busses such as:

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

(1 ms).

 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. The following devices can be connected:

 ibaFOB cards incl. ibaFOB x/4-F (ISA) and ibaFOB-OF-Link

 ibaLink-SM-64-io (Siemens Simatic S5 115U, 135U 155U; MMC216 all types)

 ibaLink-SM-128V-i-2o (VME32 & VME64 rack)

 ibaNet750 (Wago IO system 750)

 ibaBM-FOX-i-3o (FO-splitter and repeater)

 ibaPADU-8. ibaPADU-8-ICP, ibaPADU-8-M, ibaPDAU-8-S, ibaPADU-16.

ibaPADU-16-M-2. ibaPADU-32-T, ibaPADU-32-R and ibaPADU-8-O

 ibaBM-SLM (Simolink Monitor for Siemens Motion Link Bus)

 ibaBM-DDCSM (Monitor for ABB DDCS+ Drivebus)

 Adjustable bus timing (ring topology in combination with ibaLogic only!)

 Easy handling without the termination problems of copper based systems

 The integration in hazardous areas is no problem in terms of EMI due to the fiber

optic communication concept.

 One source can be accessed by multiple clients at the same time by just multiply

ing the optical fibers (ibaBM-FOX-i-3o and ibaFOB-OF-Link splitting devices) – so

I/O peripherals may be used for process control and measuring at the same time.

This also makes redundant structures easy.

Introduction

The board ibaFOB-2io-X is a fiber optic communication card like the other well-known

boards ibaFOB-io-PCI, ibaFOB-io-S, ibaFOB-4i-PCI, ibaFOB-4i-S, ibaFOB-4o and iba

FOB-OF-Link which are used to connect a standard PC to the iba peripheral devices

such as ibaPADUs, ibaNet750 devices and ibaLink signal modules (SM).

The essential difference to the boards without the “X” in the name is a higher data trans

mission rate on the fiber optic link. Of course, in order to take advantage of this enhanced

data rate there should be the appropriate peripheral devices installed which support the

high data rate too. On one hand these are devices from iba which care the “X” in the

name and on the other hand system components of other manufacturers like ABB AC

800 PEC or Simatic TDC with LO5A interface.

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

as ibaFOB boards.

What’s new?

The ibaFOB-2io-X and respectively the ibaFOB-4i-X and ibaFOB-2i-X card represent the

new generation of iba’s fiber optic PC boards. These boards extend the existing board

family and will replace the previous ibaFOB-cards in long-term. The new boards are

100% compatible on the fiber optical bus side while in the PC the interface and dual port

ram layout differ between the old and new boards.

The ibaFOB-TDCexp card couples the iba Process Data Acquisition system ibaPDA with

the Siemens control system SIMATIC TDC. To achieve this, the ibaFOB-TDCexp card

must be connected to one of the free ports of the CP52IO (GDM Interface Module of the

SIMATIC TDC).

The CP52IO realizes the access to the GDM memory card CP52M0. Using a fiber optic

link the TDC racks are connected to the CP52IO via the CP52A0 card. Up to 44 TDC

racks can be connected to the GDM in total. For the TDC system, the ibaPDA PC with

an ibaFOB-TDCexp card acts like a TDC rack, the ibaFOB-TDCexp card acts like a

CP52A0 card.

This topology enables the ibaPDA system with an ibaFOB-TDCexp card to communicate

notionally with every processor in one of the connected TDC racks (max. 43).

Operational modes

To measure SIMATIC TDC system numeric and binary values must be transported be

tween the TDC system and the PC, which means that internal variables of the TDC sys

tem may be visualized and recorded. For recording purposes two different software pack

ages are supported by the ibaFOB-TDCexp card:

 SD-TDC-lite:

All values to be measured by ibaPDA have to be manually programmed in CFC

charts of the control unit. Changes of signals require a change in this chart. Up to

16 process telegrams are to be defined per card which transport the values to

ibaPDA containing 32 analog plus 32 digital variables each. Structure and length of

the process telegrams are determined by ibaPDA. Up to 4 cards in a PC are sup

ported by ibaPDA.

In addition the ibaPDA-Technostring (non-structured ASCII-string with a length of up

to 512 bytes) can be configured.

 SD-TDC-Request:

The definition of the signals to be measured is independent of the connected con

trol unit system. All changes are done in ibaPDA. ibaPDA supports the functionality

to select the internal TDC variables by their names, i.e. the chart, function block and

the connector names. To do that for every TDC CPU special service function blocks

must be included in the CFC chart of the control unit.

The information about the variable names (address books) is transferred from the

TDC CPU to the ibaPDA system directly via the ibaFOB-TDCexp card.

ibaPDA supports up to 4 cards with up to 50 processor connections per card and

additionally, the ibaPDA-Technostring.

Introduction

Application

The ibaFOB-TDCexp card couples the iba Process Data Acquisition system ibaPDA with

the Siemens control system SIMATIC TDC. To achieve this, the ibaFOB-TDCexp card

must be connected to one of the free ports of the CP52IO (GDM Interface Module of the

SIMATIC TDC).

Characteristics

The card has the following characteristics:

 PCI Express card for 1.0-x1 compatible slot

 100 % functional compatible with the predecessor ibaFOB-TDC

 Firmware update without dismounting the card

 Bidirectional fiber optic link with 640 Mbit/s

 Absolutely noise free acquisition of process data

 Enhanced SIMATIC TDC system diagnostics

 Display for card id, processor and link status via 7-segment display and LEDs

 Up to 4 PCIe cards per PC

 Plug and play installation

 All component parameters are 100% controlled by software. No wiring or jumpering

is necessary for that card.

Remarks on the measurement principle

To measure SIMATIC TDC system numeric values must be transported between the

TDC system and the PC, which means that internal variables of the TDC system may

be visualized and recorded. For recording purposes two different software packages

are provided by iba.

Request-TDC (former name Symbolic Request):

The definition of the signals to be measured is independent of the connected system.

All changes are done in ibaPDA. ibaPDA supports the functionality to select the internal

TDC variables by their names, i.e. the plan, function block and the connector names.

To do that for every TDC CPU 2 service function blocks must be included in the CFC

plan of the TDC system. These function blocks support also overload protection to

avoid high system loads by ibaPDA.

The information about the variable names (address book) is not provided by the TDC

engineering software, but is transferred from the TDC CPU to the ibaPDA system di

rectly via the ibaFOB-TDC card.

Remarks concerning SIMATIC TDC

The coupling partner on the SIMATIC TDC side is the Interfacemodul CP52IO. This

card is located in a slot of the Global Data Memory (GDM) Rack, the common commu

nication memory within a multirack SIMATIC TDC system. The fiber optic connection

(FO) may use any free port of any CP52IO.

The CP52IO realizes the access to the GDM memory card CP52M0. The TDC racks

are connected to the CP52IO via the CP52A0 card. The ibaPDA PC with his ibaFOB

TDC card acts like a SIMATIC TDC rack with a CP52A0.

This topology enables the ibaFOB-TDC to communicate notionally with every proces

sor in one of the connected racks (max. 43). This would be up to more than 800 CPUs.

In reality the amount of simultaneous accessible CPUs per ibaFOB-TDC is

limited to 50.

In large systems it makes sense, to equip the ibaPDA-system with several ibaFOB

TDC cards, connected parallel to one GDM.

It is also possible to access one GDM by multiple ibaPDA systems. In this case it is

mandatory to use unique link names for the different ibaPDA systems. It is also re

quired that one TDC CPU is accessed by only one ibaPDA system.

Remarks on the measurement principle

To measure SIMATIC TDC system numeric values must be transported between the

TDC system and the PC, which means that internal variables of the TDC system may

be visualized and recorded. For recording purposes two different software packages

are provided by iba.
