2 Introduction
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 process monitoring purposes as well as in control system applications,
such as the ibaLogic SoftPLC.
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.
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 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, A64
Supported data transfers: 8/16/32 bit (D08/D16/D32/MD32)
8/16/32 bit block transfer modes are supported (BLT)
64 bit block transfer mode is supported (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 is a passive slave board on the VMEbus, i.e. no active master access
on the VMEbus will be performed. The board occupies a 256 kByte address space on
the VMEbus.
Coherent mode
The exchange of VME and fiber optic data happens asynchronously from each other.
This means that blocks of data that are written on the VME side are not necessarily
transported over the fiber optic telegram as one block. There is only some coherence
guaranteed based on the type of write access that was used (byte, word or dword).

Manual
ibaLink-VME

Issue 1.8
When coherent transmission of a complete block of data is needed, a special ‘Coherent
Mode’ could be enabled by setting a DIP switch. Now the VME receive and transmit
buffers are only updated when the user writes to a special Update Register. In this way
it is possible to keep blocks of coherent data together.
Fields of application
3Mbit protocol
When using the 3Mbit ibaNet protocol, all iba devices supporting this protocol can be
connected to the input and output. The following applications are possible:
Computer coupling to SIMATIC S5, SIMIKRO MMC and SIMADYN D
(ibaLink-SM-64-io and –SD-16)
Input and output of peripheral signals (e.g. ibaPADU-8, -16, -32, -8-O,
ibaNet750-BM)
Coupling to ibaLogic-V3, ibaLogic-V4, ibaPDA (all ibaFOB cards), can also be cas-
caded with ibaPADU and ibaNet750
Bidirectional coupling to a Profibus master, e.g. SIMATIC S7 (ibaBM-DPM-S-64)
Multiplying output signals (ibaBM-FOX-i-3o(-D))
see description chapter 7.2.1
32Mbit P2P protocol
Using the fast P2P protocol the following connections are possible, depending on the
telegram type:
Fast computer coupling (up to 50µs) between VMEbus based automation systems,
e.g. SIMATIC TDC, HPCi, LOGIDYN D (ibaLink-VME)
Fast computer coupling to ibaLogic-V4 (iba-FOB-xx-D and ibaFOB-io-ExpressCard)
Computer coupling to systems with embedded iba-FPGA, e.g. ABB AC800 PEC
Fast connection to I/O peripheral devices, e.g. ibaPADU-S-IT with ibaLogic
Connection to SINAMICS LINK (ibaBM-SiLink)
Connection to a collector and distributor (ibaBM-COL-8i-o and ibaBM-DIS-i-8o)
see description chapter 7.2.5
32Mbit Flex protocol
Using 32Mbit Flex protocol ibaLink-VME is compatible to all 32Mbit Flex-enabled iba-
devices.
ibaLink-VME can be connected within a ring to these devices. But the card cannot com-
municate with the other devices, only with the Flex master (at the moment only ibaPDA)

7.1.1 Fiber optic connections
Channel 1: X11 RX (4) and X10 TX (5)
Channel 1 communicates bidirectionally with compatible devices over the RX and TX
interface ports. RX realizes the fiber-optic receiver while TX realizes the fiber-optic trans-
mitter.
Possible data transmission see chapter 7.2 “Operation modes”.

Manual
ibaLink-VME

Issue 1.8
Channel 2: X20 TX (8)
X20 TX realizes the second fiber-optic transmitter (channel 2).
X20 can be used as the second channel output in 3Mbit mode. When working in other
modes the X20 output is a copy of the channel 1 output (X10). X20 can be used for
diagnostics.
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.
62.5/125 μm, 50/125 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 11.3.
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 11.1 "Technical
data" under "ibaNet interface".
7.1.2 Rotary switches
S1 „Mode“ (2)
This switch sets the mode of operation for the ibaLink-VME interface card. The modes
of operation vary in the used ibaNet protocol, the transmission rate, size and format of
the telegrams.
See chapter 7.2 “Operation modes”.
S2 “Range” (6)
In 3Mbit cascading mode the range switch specifies the range of channels within a cas-
cade to be transmitted over the fiber-optic link.
See also section 7.2.1 and 9.3 ”Cascade Mode 3Mbit”.
In 32Mbit P2P mode the range switch is used to select the FO telegram type.
See also section 7.2.5 “ibaNet 32Mbit P2P (mode 4)”.
In 32Mbit Flex mode the range switch is not used.
S3 “Address” (7)
In 3Mbit mode this switch defines the starting position of the local data in the daisy-
chain. Valid values: 1…8. If channel 1 is not operating in daisy-chain mode the switch
setting should be 1.
See also section 7.2.1 and 9.3 ”Cascade with 3Mbit mode”
In 32Mbit Flex mode the address switch specifies the address of the device within a ring
topology of 32Mbit Flex enabled devices. Possible settings: 1…F.
See also section 7.2.6 and 9.4 “Cascade with 32Mbit Flex”.
Default settings of the rotary switches:
S1 Mode: F (32Mbit Flex mode)

7.2.1 ibaNet 3Mbit (mode 0)
Channel 1 receives and transmits 64 analog and 64 digital input and output signals at
1 ms rate. This mode allows cascading of up to 8 devices. The S2 Range switch specifies
the range of channels within a cascade to be transmitted over the fiber-optic link. Valid
settings are 1…8 (valid for each 8 digital and 8 analog measured values). Up to 8 x (8
analog + 8 digital signals) can be transmitted in a cascade. The switch should be set to
8, when cascading is not used.
The S3 Address switch defines the starting position of the local data in the daisy-chain
(1…8). See also chapter 7.1.2 “Rotary switch S3 Address” and chapter 9.3 “Cascade
with 3Mbit mode”.

7.2.3 ibaNet 3Mbit P2P (mode 8)
In peer-to-peer-(P2P)-mode 2 cards can be coupled to each other, exchanging data
(64 analog and 64 digital signals) periodically in 1 ms (computer coupling). In this oper-
ation mode the two VMEbus memory ranges are transmitted from one card to the other.
S2 Range switch and S3 Address switch are ignored. The device acts as if address
switch is set to 1 and range = 8. Cascading is not possible.
The following devices can also be a partner: ibaLink-SM-128V, ibaLink-SM-64-io,
ibaLink-SM-64-SD16 or a Profibus module ibaBM-DPM-S-64. So fast computer coupling
between different systems is also possible.
7.2.4 ibaNet 3Mbit P2P with diagnostics (mode 9)
Peer-to-peer-mode is identical to the previous example (mode 8).
Channel 2: the data of channel 1 is mirrored to channel 2 and can be used for diagnostics
(e.g. data recording with ibaPDA).

7.2.5 ibaNet 32Mbit P2P (mode 4)
The “fast” peer-to-peer mode is also used to connect two cards, but more signals can be
transmitted at a higher data rate.
Channel 2: the data of channel 1 is mirrored to channel 2 and can be used for diagnostics
(e.g. data recording with ibaPDA)
The S2 Range switch specifies the transmission mode:
S2 Range

0 64 Integer + 64 Digital in 50 μsec
1 128 Integer + 128 Digital in 100 μsec
2 256 Integer + 256 Digital in 200 μsec

Note
The DIP switches for setting the telegram format (Real/Integer) are ignored, since the
format is specified by switch S2.

7.2.6 32Mbit Flex (mode F)
Example 1
Example 2
The transmission rate can be adjusted flexibly depending on the amount of data (e.g. the
fastest rate is 65 bytes at 25 µs, the maximum amount of data is 4060 bytes at 1.4 ms).
The ibaLink-VME card can be connected with up to 15 devices in a ring topology with
32Mbit Flex. 32Mbit Flex requires a FO card of the ibaFOB-D type for communication.
The diagnostic output X20 is not supported yet in 32Mbit Flex mode.
ibaLink-VME should be configured at least once. The configuration is stored on the card
until a new configuration is sent from the PC.
The address of the card in a ring is set by the S3 Address switch. The S2 Range switch
has no function in this mode.
