1. Introduction
1.4. Notational Conventions
16#••••..............Value expressed in hexadecimal, which is equivalent to the H••••, ••••h and 0x•••• notations,
sometimes used in other documents. N.B. The AbcConf software uses the 0x•••• notation.
E.g. 16#0100 = 0x0100 = 256.
02#•••• ••••........Value expressed in binary. The number of ‘•’ digits depends on the size of the item of data
represented. Each nibble (group of 4 bits) is separated from the other nibbles by a space.
Examples: byte 2#0010 0111 = 39, word 2#0110 1001 1101 0001 = 16#69D1 = 27089.
AbcConf...........Abbreviation that refers to the tool used to configure and implement the LUFP9 gateway: “ABC-
LUFP Configurator”.
ATS..................Abbreviation of “Altistart” (soft start- soft stop unit).
ATV..................Abbreviation of “Altivar” (drive).
CRC.................Cyclical Redundancy Check.
LED..................Light-Emitting Diode.
EDS..................Electronic Data Sheet. Refers to the file format (“.eds” extension) which allow a tool used for
configuring and preparing DeviceNet masters to configure their exchanges using this same
protocol.
Fieldbus........... A term referring to the upstream DeviceNet network in AbcConf.
Handshake.......An old term referring to the two registers used for initializing and carrying out diagnostics of the
LUFP9 gateway. This term has been replaced by the expression “Control/Status Byte”.
LRC..................Longitudinal Redundancy Check.
Node ................A term referring to the connection point of a Modbus slave under AbcConf.
ODVA...............Open DeviceNet Vendor Association, Inc.
LSB:.................Least significant byte in a 16-bit word.
MSB:................Most significant byte in a 16-bit word.
Sub-Network....A term referring to the downstream Modbus network under AbcConf.
XML..................EXtensive Markup Language. The language used by AbcConf to import/export the configuration
of a Modbus slave.

In the case of Modbus slaves, the features, services and adjustment of the Modbus communications are not
