1. VME-PROF-S - Overview
•• PROFIBUS-DP-Slave Interface 12 Mbaud
•• SPC3 PROFIBUS Slave ASIC
•• VMEbus Slave Interface with 64 KB Dualport RAM
•• 512 KB Boot-Flash-EPROM with DPS Firmware
•• MC68331 CPU
1.1. General Information
The VME-PROF-S is a compete
independent PROFIBUS-DP-Slave
interface on an VMEbus board. The
interface is based on the SPC3-ASIC
which handles the layer 1 / 2 of the
PROFIBUS protocol (DIN 19245 / EN
50170) and the MC68331 processor.
64 kB dualport-RAM are used as data
interface to the VMEbus.
With the PROFIBUS-DP-Slave
firmware (DPS), the VME-PROF-S
builds a independent arbitrary
configurable DP-Slave interface. The
slave is configured through the dual-
port-RAM. The configuration can be
build with max. 32 configuration bytes
and can use up to 244 input bytes and
244 output bytes. The total amount of
input / output data can be 400 bytes.
Due to the arbitrary configuration the
Slave can fit the requirements of the
VMEbus system or the VME-PROF-S
can be used to simulate other Slaves.

2. Hardware Installation and Configuration
2.1. Hardware settings
Warning
The system must be switched off when changing hardware within or connected to the
system!
2.1.1. VMEbus slave address range (Slot Address)
The VME-PROF-S use 64 kByte within the VMEbus standard range. The base address can
be selected in 64 k steps within the 16 MB address space. The address setting is done with
the addressbits (A23 - A16) at S21 / S20 . A Jumper Diagram with the default settings can
be found in chapter 7.4.
Base address: $xy0000
³ÀÄ(A19-A16)
³Set by S20.
³Default: $F
ÀÄ(A23-A19)
Set by S21
Default: $8
Note:
For 6HE VMEbus-boards (like the previous VME-PROF-S Vers. 4.x) DMS use an optionally
slot depending addressing. For this address coding some address lines (for example A19 -
A16) are connected to the J2 connector. With a binary coded J2 backplane, the slot
depending addressing can be realized for this boards.
For the VME-PROFI-S Vers. 5.x this address coding is not possible, due to the 3HE
layout of the board. The address of the board is always set by S21 / S20. If S21 use the
default setting „8“, the setting of S20 correpndents to the „slot-number“.
The „slot-number“ are used by some example and utility programs and within some other
DMS manuals.
2.2. Autorun Jumper J20
J20 selects the start-mode of the VME-PROF-S.
Open: After power-on or SYSRESET, the board will remain in the Reset-state. The
PROFIBUS controller will not start. Both red Led’s (VMEbus and PROFIBUS) will be
on
Close: After power-on or SYSRESET, the board will be reset and then the PROFIBUS
controller will start.
2.3. Final Installation

After finishing the installation align and insert the VME-PROF-S card into the designated
slot and tighten it by fastening the two screws at the top and bottom of the cards front
panel. Safe and trouble free operation can only be ensured if the card is well aligned and
tightened.
2.4. Software Setup
The VME-PROF-S DP-Slave firmware (DPS) are stored in the Flash-EPROM. Therefore no
software must be loaded into the board. The configuration of the DP-Slave parameters are
done through the VMEbus. This configuration are described in chapter 5.1.1.
2.5. How to Remove the Card
Prior to removing the card all connectors at the card's front panel need to be disconnected.
Remove the two screws at the bottom and the top of the front panel. Pressing the upper
card handle towards the upper end of the card and the lower handle respectively towards
the bottom will loosen the card. Now you can remove the card from the subrack.
2.6. Shipping and Packaging
Packing needs to be done with greatest care. The card needs to be protected from
electrostatic discharge. If possible use the original packaging.
A 'DMS Return Form' (see Appendix) must be included with all returns to DMS.

Table 3: Maximal bus length
The maximal bus length can be extended until approx. 10 km with repeaters. The max.
number of repeaters that can be used in a network depends on the type of the repeater
and is between 3 and 10.
