Introduction

EtherNet/IP (EtherNet Industrial Protocol) is a real-time Ethernet which is mainly used in

automation technology.

The EtherNet/IP bus monitor ibaBM-ENetIP is a device for acquiring the cyclical data

exchange between EtherNet/IP scanner (master) and adapters (slaves). The device can

be integrated into an existing EtherNet/IP network with one or more EtherNet/IP scan

ners (master).

The ibaBM-ENetIP bus monitor can be operated in an EtherNet/IP network without inter

ferences using the TAP interface (Ethernet). The device works as sniffer, i.e. it listens to

the cyclic data exchange of the IO data (implicit messaging) between EtherNet/IP scan

ner (master) and adapters (slaves).

The entire communication via the TAP interface is being mirrored to a monitor port and

can be recorded using an external network analysis tool.

On the optical-fiber side, ibaBM-ENetIP works with the ibaNet protocol 32Mbit Flex. With

this protocol, measuring and configuration data are transferred via a bidirectional fiber

optic connection. 

Whether the link sends in integer or float format must be defined prior to installing the

SM128V. Use the DIP switch to change this setting for each fiber optic link. Each fiber

optic link must be set independently. Data must then be written to the appropriate regis

ters.

The digital channel values may be written in channel-wise in either a DWORD for each

digital channel (bit 0 of each DWORD) or an 8 byte bit mask. Prior to sending the tele

gram the respective registers are OR’d to determine whether a 0 or 1 is sent in the tel

egram. For this reason, it is important to reset the registers of the unused method.

It’s an asynchronous take-over of data from the VME range into the buffer of the FOB

transmitter. Data coming out of the VME range will be synchronized with the 1 ms clock

of the FOB interface. Thus the take-over time for the data varies between 0 and 1 ms.

The following devices are compatible with fiber-optic channel 2 of the SM128V:

 ibaPADU-8-O,

 ibaLink-SM-64-SD16.

 ibaBM-DPM-S-64.

 ibaFOB-4i-S and ibaFOB-io-S (Input),

 ibaFOB-4i-D, ibaFOB-2i-D and ibaFOB-io-D (Input),

 ibaBM-FOX-i-3o and ibaBM-FOX-i-3o-D,

 ibaBM-COL-8i-o

Both fiber-optic output channels (Channel 1 and Channel 2) can be interfaced to indi

vidual ibaCom-PCMCIA-F cards via the X4 and X5 RJ11 sockets. Note that only one

ibaCom-PCMCIA-F card may be used at a time in a Notebook measurement PC.

The VMEbus interface

The SM128V supports a maximum of 64 input channels (a + d) and 128 output chan

nels. The card occupies 256 kByte memory space on the VMEbus. The base VME ad

dress is adjustable using the DIP switch settings as described above.

From the VMEbus viewpoint, WORDs and DWORDs can be read and written in BIG

ENDIAN or LITTLE ENDIAN format. The SM128V-card can accept both formats. The

used format has to be configured with a DIP switch.

Application Notes

The optical fiber input/output links operate at 3.3 Mbps.

The following components are compatible with fiber-optic channel 1 of the SM128V:

 ibaLink-SM-64-io (but mixed cascade of ibaLink-SM-64-io and SM128V is not sup

ported),

 ibaLink-SM-64-SD16.

 ibaBM-DPM-S-64.

 ibaPADU-8. ibaPADU-8-I, ibaPADU-8-O,

 ibaFOB-4io-S and ibaFOB-io-S,

 ibaFOB-4io-D, ibaFOB-2io-D and ibaFOB-io-D,

 ibaBM-FOX-i-3o and ibaBM-FOX-i-3o-D,

 ibaBM-COL-8i-o, ibaBM-DIS-i-8o

The following operation modes are supported on channel 1:

 I/O operation; up to eight devices connected to the fiber-optic input (Rx) and up to

eight devices connected to the fiber-optic output (Tx)

 Cascade operation with daisy-chain of up to eight SM128V cards

 Addressing of input and output data in steps of eight signals.

Channel 2 provides 64 channels for transmission only.
