IBA ibaLink-io-embedded Integrated system interface for OEM systems

Introduction

ibaLink-io-embedded is an embedded module for OEM customers, that allows to ex

change data over fiber optic (FO) with iba measuring systems. The module can be inter

faced via DPRAM.

When integrating the ibaLink-io-embedded module into an application, the system inte

grator is responsible for the CE/EMC conformity of the entire device.

 Current consumption max. 0.4 A (2 W)

 Connector male 44 pin header (2 x 22 pins, 2 mm pitch)

 Bidirectional fiber optic link for analog and digital inputs and outputs

 Supported ibaNet protocols: 32Mbit, 32Mbit Flex

 Flexible setting of data rate, data size and formatting with 32Mbit Flex

 Different operation modes (cascading, point-to-point)

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.

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

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.

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.
