Glossary
No. Term Definition
A Address
(Station address)
Number allocated to identify each unit connected on PROFIBUS DP network. Address number is not
permitted to be duplicated.
C Communication speed
Data receive and transmit speed used by the fieldbus. This depends on master equipment (PLC etc.),
the unit used is bps (bit per second).
C Current consumption The amount of current required by each unit in order to operate.
D Diagnostic information
Diagnostic information consisting of standard diagnostic information from both the PROFIBUS DP and
the EX600.
D DIN rail Metal rail in accordance with the DIN standard.
D D side The DOWN side of the manifold, where EX600 end plate is connected
F FAIL SAFE function When PLC (DP master) is at clear mode, it sends data packet of output data with data length =“0”. As
a result the slave will be set to a defined state (Hold/Clear/Force ON).
F FE Functional Earth.
F Fieldbus Type of communication system between a PLC and factory equipment (such as measuring
instruments or machines), in which data is exchanged by digital communication.
F FREEZE function Function that synchronizes input data of SI unit with FREEZE Command from PLC (DP master).
G GSD file General Station Description file. This is a file that describes the product characteristics for
configuration with PROFIBUS DP system.
H Hand-held terminal
(HT)
A unit to connect with the SI unit PCI connection, for parameter adjustment, to monitor all input and
output signal status, and for Forced input/output selection.
I ID No. 16 bit number which is assigned by PNO to identify the product
I Idle Condition when SI unit (PROFIBUS DP) receives FAIL SAFE command. Using parameter setting,
output can be set to CLEAR/HOLD/Force ON.
I Input points Number of points that which can receive information from input equipment. (Sensor and switch, etc.)
M Manifold An assembly with many openings for receiving and distributing fluid or gas.
N NPN output Output that switches a load through an NPN transistor. The +ve side of the load is connected to a
common +ve. For this reason, NPN output is often referred to as “common positive”.
N NPN input Input that receives data from sensor with an NPN output signal.
O Open circuit detection Diagnostic function that detects open circuit, caused by broken or disconnected wiring to the
input/output equipment.
O Output points Number of points of output equipment (Solenoid Valve, lamp, motor starter, etc.), which can be
operated.
P PLC Programmable Logic Controller. A Controller which performs sequential control using programs of
logical, order and arithmetic operation, etc.
P PNP output Output that switches a load through a PNP transistor. The –ve side of the load is connected to the 0 V
common return. For this reason, PNP output is often referred to as “common negative”.
P PNP input Input that receives data from sensor with PNP output signal.
P PROFIBUS DP Fieldbus that Siemens, Bosch, and ABB, etc. jointly developed in Germany in 1980's. PNO
(PROFIBUS Nutzerorganisation e.V.) is started in order to spreads the PROFIBUS.
P Protection class
(IP□□)
International Protection Rating. A Standard related to protection against foreign objects into electrical
enclosures. (Hand, wire, dust, and water, etc.)
S Short circuit detection Function that detect if output or power supply positive line is short circuited with GND, thus over
current state has occurred.
S Short circuit protection Internal circuit protection to prevent damage by over current caused by power supply positive line
being short circuited with GND
S SI unit Serial Interface unit. A unit for connection with a PLC to perform input/output data
communication.
S SYNC function Function that synchronizes output data of the SI unit with a SYNC command from a PLC (DP master).
T Terminating resistance
When connecting devices to the fieldbus, resistance must be installed on both ends of the wiring
system. This prevents signal reflection and maintains data integrity.
U U side The UP side of the manifold, where solenoid valve manifold is connected.
