2 Introduction

ibaNet750-BM-D is a device designed to extend the range of iba I/O functionalities using

the I/O modules of the series 750 produced by WAGO and terminals for the K-bus by

Beckhoff. The device acts as a gateway between the serial K-bus and the deterministic

fiber optic ibaNet protocol.

The WAGO I/O system is the ideal supplement for the range of the peripheral devices.

Digital and analog WAGO/Beckhoff I/O terminals as well as incremental encoders, SSI

inputs, resistance thermometers, thermocouples and measuring bridges can be inte-

grated into the system.

Up to 255 WAGO I/O terminals can be connected to ibaNet750-BM-D and a data volume

of up to 2048 Bytes can be transferred over the K-bus.

The signals are internally converted and are available via the fiber optic interface. For

the connection to a data acquisition system, such as ibaPDA, an ibaFOB-D card is used

with a bidirectional fiber optic cable connection.

The device supports different ibaNet protocols:

32Mbit Flex

Using 32Mbit Flex, configuration as well as process data is transmitted via a bidirectional

fiber optics connection. ibaPDA automatically detects the modules used and the signals

can be easily selected and configured by mouse click.

With 32Mbit Flex, the sampling rate can be flexibly set up to 40 kHz. The maximum data

volume to be transmitted depends on the adjusted sampling rate. The following rule ap-

plies: the higher the sampling rate, the lower the data volume. The ibaPDA application

automatically determines the maximum sampling rate, which depends on the desired

data volume and the number of devices in the ring.

With the ibaNet protocol 32Mbit Flex, it is possible to connect up to 15 devices to a ring

topology. The signal limitation applies for the entire ring. Thereby, the distance between

the devices can be up to 2 km. Other 32Mbit Flex-enabled iba devices can be integrated

into the ring as well.

32Mbit

The 32Mbit protocol is especially used with ibaLogic-V4 version 4.2.5.464 or later. With

the 32Mbit protocol it is possible to connect an ibaNet750-BM-D system to ibaLogic with

a data transmission rate of 32 Mbit/s. The cycle time is 500 µs and up to 256 (REAL) /

512 (INT) analog and digital signals are transmitted. A bidirectional fiber optic connection

is necessary in order to integrate output terminals.

3Mbit

Using the 3Mbit protocol, the device is compatible to the previous ibaNet750-BM version.

Up to 8 devices may be connected in a line topology and used as pure input or output

devices. If input and output signals should be processed at the same time, it is recom-

mended to use a ring topology. Moreover, the devices may operate peer-to-peer without

a PC involved. The cycle time is 1 ms in all applications.

Note

Please note, that the modes 1 and 3 of the previous device ibaNet750

-BM are not sup-

ported

any more.

Characteristics in 3Mbit mode:

 Works as input and output station at the same time

 32+32 analog inputs and outputs plus 32+32 binary inputs and outputs per station

or

 Up to 512+32 binary inputs plus 512+32 binary outputs

or

 Eight complex terminals (i.e. SSI, incremental encoder etc.),

 Fiber optic compatible with ibaPADU-8 and ibaPADU-8-O, that means up to 8

ibaNet750-BM-D I/O-devices on 1 bus (ring or star topology)

 Integrated power supply for the modules (internal load up to 1.5 A)

 For operation with ibaPDA there are restrictions regarding the time behaviour of the

terminals (no guaranteed simultaneous plant snapshot of all signals within 1ms cy-

cles).

 Operation without PC. Using this device mode, it is possible to replace conventional

copper wire bundles with ibaNet750-BM-D devices (up to 8x 136 digital signals in

each direction on 2 fiber optics).

The behavior of the device at the iba fiber optics bus is identical to one or four ibaPADU-

8, ibaPADU-8AI-U/-I or ibaPADU-O devices. That means, that every device can send

and receive 8 (or 32) analog channels (16 bit each) and 8 (or 32) binary channels (8 bit),

in total 17+17 (68 + 68) Byte net data cyclically every millisecond. The devices can be

cascaded like ibaPADU-8 (ibaPADU-8-O) devices, with up to 8 devices per cascade. The

device converts the incoming data stream from the fiber optic link simultaneously and

exactly to the millisecond for all channels, regenerates the optical signal and sends it to

the other devices within the cascade. It is allowed to mix ibaPADU-8, ibaPADU-8-O and

ibaNet750-BM-D devices within an optical link.

An ibaFOB-D input card is required on the PC side. If ibaNet750-BM-D is used as re-

placement for the predecessor ibaNet750-BM, even older PC cards (ibaFOB-io, ibaFOB-

4i and ibaFOB-4i-S) can act as receivers.

Additionally each station can simultaneously be used as output device (like ibaPADU-8-

O). This is in particular necessary when terminals with set/reset function are used, e.g.

counter etc. For this purpose, an ibaFOB-D card with output(s) is required on the PC

side.

To add more functions, ibaNet750-BM-D can also be used with the ibaLink-SM-64-io,

ibaLink-SM-128V-i-2o or ibaLink-VME card. This allows to create simple I/O extensions

for the systems Siemens Simatic S5 115U, 135U, 155U, as well as Siemens MMC216

and VME buses.

Note

Data transmission

: Every ibaNet750-BM-D device can transmit exactly 17, 34

or 68

input bytes plus 17, 34 or 68 output bytes in 3M

b

it mode, whereby inputs and outputs

are operated simultaneously

Note

I/O range 1

: Not all WAGO IO terminals may be usable. Please contact iba to make sure

the specific terminal will work.

This also applies to the (basically) compatible Beckhoff

terminals.

See also the tables in chapter 10 “Terminal types”.

Note

I/O range

2: There are 4 different terminal types:

-

Digital IOs (easy to handle)

-

Analog IOs (easy to handle)

-

Complex terminals (require more knowledge of the terminal design than usual)

-

Configurable terminls (ibaNet 32Mbit Flex only, must be configured before use)

Before project engineering, check for

each terminal type which tr

ansmission capacity is

required

.

Note

Terminal diagnostics

: With the exception of complex terminals no diagnostic infor-

mation is supported

.

Note

Compatibility

in 3Mbit mode: The fiber optic telegram definition of ibaNet750-BM-

D is

100% compati

ble to the existing ibaPADU-8 devices.

ibaPDA restrictions

While all iba devices normally deliver exactly 1 ms synchronized simultaneous snap-

shots of the process, this cannot be guaranteed when using the WAGO750 I/O system

.

This is caused by the fact, that the WAGO modules are themselves running with a serial

bus which is totally independent from the ibaNet bus. Further on, the cycle time depends

on the number of channels connected to a station. Especially analog channels and

counters (terminals with a high number of bits) decrease the bus cycle, and cycle times

may take several milliseconds. When several stations are used simultaneously,

different

cycle times may cause phase differences of up to 10 ms. This means the simult

aneous

measurement of a huge number of signals < 10 ms cannot be guaranteed.

Anyway, to

measure some additional RTD or thermocouple inputs this timing is sufficient.

Delivery state

7.4.1.1 3Mbit normal mode

In 3Mbit normal mode, all connected terminals are supported with their standard input

and output signals.

7.4.1.2 3Mbit ECO mode

Using 3Mbit protocol, the so called ECO mode is available besides normal mode. The

ECO mode was developed for some complex terminals which usually require a larger

memory space for inputs and outputs in normal modeSince only a few input bytes are

required for some applications, the address range used for these special terminals has

been reduced. Consequently, not all available bytes provided by a terminal are used in

the ibaNet telegram, e. g. only four input bytes instead of eight input and eight output

bytes are transmitted in the telegram.

As a result more terminals of the complex type can be used with one ibaNet750-BM-D

device. Currently, the ECO mode is supported for the following complex terminals:

 SSI Terminal (750-630)

 Incremental Encoder Terminal (750-631)

All other terminals of type A (digital) and B (analog) will run in normal mode although the

switch is set to ECO mode.

7.4.2 Rotary switch S2 (device address)

The rotary switch S2 has different functions depending on the used device mode.

Other cycle times are not supported at the moment.

3Mbit and S1 = 0, 2, 8 or A

The rotary switch S2 is used to set the device address. Valid addresses are 1…8 and

A…F. The position of the device in the chain may differ from the address setting of the

device.

With switch in positions 1...8 the ibaNet750-BM-D device behaves like an ibaPADU-8

device and uses its device address (1…8) for eight binary and eight analog IOs.

In positions A or B the ibaNet750-BM-D device uses four device addresses

(A = 1…4, B = 5..8) and hence is able to transmit up to 32 binary and 32 analog IOs.

In positions C…F the ibaNet750-BM-D device uses two device addresses

(1+2, 3+4, 5+6, 7+8) and hence is able to transmit up to 16 binary and 16 analog IOs.
