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.

Operational modes

The following operational modes are supported by ibaFOB-TDC:

 ibaPDA-lite-SD-TDC software interface: Max. 4 cards with up to 512 analog plus

512 digital values are supported by this software (16 telegrams with 32 analog

and 32 digital values each);

Supports a non structured so called ASCII Techno string via the TDC link.

 ibaPDA-Request-TDC package: Max. 4 cards with up to 50 processor connec

tions (32 analog plus 32 digital signals each) and a total of up to 1024 analog

plus 1024 digital signals for one ibaPDA;

Supports one non structured so called ASCII Technostring via the TDC link.

 Bi-directional SD/TDC-Lite connection for the ibaLogic Soft-PLC: Max. 4 cards

with up to 512 analog plus 512 digital input values and 256 analog plus 256 digi

tal values; Supports the non structured so called ASCII Technostring via the TDC

link

Introduction

Assignment

The ibaFOB-TDC card couples the iba Process Data Acquisition system ibaPDA or the

Soft-PLC ibaLogic with the Siemens control system SIMATIC TDC. To achieve this, the

ibaFOB-TDC must be connected to one of the free ports of the CP52IO (GDM Interface

Module of the SIMATIC TDC).

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

necessary for that card.

Characteristics

The card has the following characteristics:

 Bi-directional fiber optic link with 640 MBit/s

 Absolutely noise free acquisition of process data

 Enhanced SIMATIC TDC system diagnostics

 Up to 4 ibaFOB-TDC cards per PC

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

 Plug and Play installation

Extension modules

Each card can be extended with up to 2 add-on modules ibaFOB-4o-D. Two designs are available

for the extension modules:

■ Short, for ibaRackline (special housing slots)

■ Long for standard PCI slots or PCIe slots 1.0-x1 compatible

The extension modules should be connected by a flat ribbon cable with the card. Depending on

the intended function the module should be plugged into the appropriate connector.

■ Mirroring the optical inputs

The optical input channels are mirrored on the output channels, with almost no delay. Thus,

other iba systems equipped with ibaFOB input boards can be supplied with the same mea

sured data.

■ Outputs of application software

In this case the ibaFOB-4i-D board operates in duplex mode, i. e. signals can be received

and transmitted independently. With ibaPDA you are able to use the alarm outputs, with

ibaLogic you are able to use these output channels as output resources.

Properties

■ PCI cards: Full compliant PCI V2.2 card, supporting both 3.3 V and 5 V signal levels and sup

porting both 33 MHz and 66 MHz PCI bus clock speed

■ PCI Express card: PCIe 1.0-x1 compatible slot (PCIe-x1. x4. x8. x16)

■ Measurement data is written directly to the computer’s main memory or read out without

loading the CPU (PCI bus master DMA).

In DMA mode, the drives access the memory directly. This is a significant relief for the CPU

load while data traffic is boosted.

■ Independent fiber optic input channels

■ All currently existing ibaNet link protocols are supported:

2Mbit (for ibaPADU devices with S/N < 1000)

3Mbit

5Mbit

32Mbit

32Mbit Flex

■ 4 LEDs for each input channel indicating operational status, link status, data transmission

rate and error

■ 7 segment display for card-ID and indication of sync master card

■ Expansion connector (white) for ibaFOB-4o-D module to mirror the inputs

■ Extension plug (black) for add-on module ibaFOB-4o-D for transmitting analog and digital

output signals

Possible applications: ibaLogic outputs or alarms from ibaPDA and ibaPADU-8-M/-ICP bi-

directional connection

■ No jumpers or switches on the card

All parameters are set in the software.

■ Interrupt synchronization cable to connect multiple iba cards in one PC

■ Firmware upgrade without uninstalling the card.

General application

The cards of the ibaFOB-D family are communication cards for ibaNet fiber optics connections

using DMA technology (DMA = Direct Memory Access). Mechanically, they have a standard de

sign for PCI slots or PCI Express slots.

The cards are the successor models for the cards in the ibaFOB-S and ibaFOB-X families and can

replace these former models completely.

The ibaFOB-D cards can be used to connect iba peripheral devices such as ibaPADU analog-digi

tal-converters, ibaNet750 devices, ibaLink signal modules and ibaBM bus monitors to a standard

or industrial PC. The cards can also be used for connecting an iba-system to automation devices

of other manufacturers, e. g. ABB AC 800PEC or SIMATIC TDC-interface boards LO5/LO6.

The cards have different numbers of fiber optic inputs which can be operated with different

communication protocols depending on the connected devices.

The boards cover all current and former ibaNet communication protocols and thus can be

used for processing of data from an old ibaPADU device (S/N <1000) and an ABB 800PEC high

performance controller or a SIMATIC TDC LO6 board as well. The 5Mbit protocol is also sup

ported by iba. This enables the cards to measure fast signals (25 kHz) from an ibaPADU-8-ICP,

ibaPADU-8-M or ibaPADU-16-M.
