About ibaLink-VME

The ibaLink-VME interface card is a multi-purpose, bidirectional interface card designed for use

in VMEbus compatible PLCs and computer systems. It may be used for data acquisition and pro

cess monitoring purposes as well as in control system applications, such as the ibaLogic soft PLC.

ibaLink-VME is the successor of the ibaLink-SM-128V-i-2o card (also called here SM128) and

completely compatible with the previous functions in 3Mbit mode. In addition ibaLink-VME

offers new functions using the ibaNet protocols 32Mbit and 32Mbit Flex.

The key features of the card include:

■ 1 bidirectional fiber-optic link for inputs/outputs (channel 1)

■ 1 unidirectional fiber-optic link for outputs (channel 2)

■ ibaNet protocols 3Mbit, 32Mbit and 32Mbit Flex

■ Flexible data selection and rate setting with 32Mbit Flex

■ Cascading of up to 15 devices in 32Mbit Flex mode at channel 1

■ Compatible interface for all ibaFOB cards

■ Compatible process I/O interface for ibaPADU-8-IO series and ibaNet750-BM series

■ Block coherent mode

■ Data exchange between 2 systems in Peer-to-Peer mode (P2P)

The ibaLink-VME card can be used in both VME32 and VME64 systems (6U height).

5 V power supply is required (from VMEbus).

VME specification according to ANSI VITA 1-1994:

■ Supported addressing modes: A24. A32. A40 and A64

■ Supported data formats: 8/16/32 Bit (D08/D16/D32/MD32)

■ Supported block transfer modes: 8/16/32 Bit (BLT)

■ Supported block transfer modes: 64 Bit (MBLT)

■ Support for unaligned transfers (UAT) and read-modify-write (RMW)

The following modes are not supported:

■ Auto configuration (AutoSlotID)

■ 2eVME/2eSST

The ibaLink-VME card is a passive slave board on the VMEbus, i.e. no active master access on

the VMEbus will be performed. The card occupies 256 kByte memory space on the VMEbus.

What’s new?

The ibaFOB-4i-X and respectively the ibaFOB-2io-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 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, asynchronous 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

In X-mode considerably more signals can be transmitted in the same time, up to

512 Signals / ms.

 Enhanced card diagnostics and card information in ibaPDA-V6

 PCI-X compatible

The card can be operated in PCI-X slots, though the PCI-X mode (64 bit ac

cess) is not supported.

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-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 (ground

loops, termination etc.)

 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-4i-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.

The ibaFOB-4i-X can be extended by means of the add-on module ibaFOB-4o-X with

four fiber optic output ports in order to get a device with full input-output functionality (e.

g. with ibaLogic).

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

as ibaFOB boards.

32Mbit P2P mode

You should use 32Mbit P2P mode, if

 there is only a single fiber optic cable available or

 you want to connect two ibaLink-io-embedded modules or

 you want to connect an ibaLink-io-embedded module to ibaLogic.

In this mode, the module has to be configured as described in chapter 7 “Software” and

the user has to ensure that the complete signal configuration of the application is also

set up correctly in the 2nd device (ibaLink-io-embedded, ibaPDA or ibaLogic).

32Mbit mode

In 32Mbit mode, up to 16 ibaLink-io-embedded modules can be connected in a ring with

ibaLogic. ibaLogic can read and write process data to all devices in the ring. The devices

can read all data which is currently on the fiber optic link, but can only write data on their

parts of the fiber optic link.

The application has to ensure, that only the allowed signals at the correct location in the

fiber optic buffer are used. The configuration of the ibaLink-io-embedded module will

check this. If the configuration is wrong, it will not be applied and the red LED is blinking.

The rotary switch of the ibaLink-io-embedded is used to select the device number (0 to

F). It is not allowed to have two devices in the ring with the same number.

Scope of delivery

After unpacking check the completeness and intactness of the delivery.

The scope of delivery of “HDK ibaLink-io-embedded“ (order no. 60.700204) includes:

 ibaLink-io-embedded module (order no. 14.132400)

 2nd ibaLink-io-embedded module as test board (modified)

 Ribbon cable (2×22 pin, RM 2.0 mm)

 2 pin cable for power supply

 Data medium “iba Software & Manuals”

Connections

FO interface

The module communicates with compatible devices over the fiber-optic RX and TX in

terface ports. RX realizes the fiber-optic receiver while TX realizes the fiber-optic trans

mitter.

32Mbit Flex mode

32Mbit Flex is the preferred mode for data acquisition applications with ibaPDA. ibaLink

io-embedded has to be configured at least once, see chapter 7 “Software”. The ibaPDA

application reads the configuration and displays the configured signals. The user can

select the signals to be measured and adjust the cycle time. The cycle time can be faster

for small amounts of data, up to 10 μs with 17 Bytes. The maximum amount of data is

4060 Bytes at 1.4 ms. The data format and size can freely be set. The application can

use the complete RX and TX buffer (4060 Bytes).

32Mbit Flex requires a bidirectional FO connection to a card of the ibaFOB-D type for

communication. With 32Mbit Flex, it is possible to connect up to 15 devices in a ring

topology.

Maximum distance of fiber optic connections

The maximum distance of fiber optic connections between 2 devices depends on various

influencing factors. This includes, for example, the specification of the fiber (e.g.

50/125 μm, 62.5/125 μm, etc.), or the attenuation of other components in the fiber optic

cable plant such as couplers or patch panels.

However, the maximum distance can be estimated on the basis of the output power of

the transmitting interface (TX) or the sensitivity of the receiving interface (RX). A model

calculation can be found in chapter 10.2.

The specification of the transmitter’s output power and the receiver’s sensitivity of the

fiber optic components installed in the device can be found in chapter 10 “Technical data”

under “ibaNet interface”.

32Mbit Flex mode

32Mbit Flex is the preferred mode for data acquisition applications with ibaPDA. ibaLink

io-embedded has to be configured at least once, see chapter 7 “Software”. The ibaPDA

application reads the configuration and displays the configured signals. The user can

select the signals to be measured and adjust the cycle time. The cycle time can be faster
