Master Station
A station residing in the equipment (typically, PLS or personal computer) which
controls a data link system. There must be at least one Master Station in any
system. As described below, Master Station comes in two varieties: Class 1 and
Class 2.
Class 1 Master Station
Equipment which exchanges input/output data with Slave Stations.
Class 2 Master Station
Equipment
which verifies station number settings and operating statuses through
communications with Slave Stations. It serves as a network administration master
station and takes care of such tasks as startup, maintenance service, and
diagnosis.
Slave Station
A lower-level station which communicates with Master Station.
Repeater
A device which provides a link between the segments of a PROFIBUS DP network.
Terminator resistor
Resistor connected to the individual
segments of a PROFIBUS DP network at each
end. Actua
lly, terminator resistors built in the connector used with a PROFIBUS
network are enabled to fulfill intended purposes.
Slave parameter
Slave station parameter established
by Master Station. Items of parameter
information are stated on a GSD file.
Station number
A number assigned to Master Station or Slave Station. Numbering is in the range of
0 to 125.
I/O configuration
information (data module)
Information about input/output configuration at Slave Station.
Input data
Data which is sent by 2D
-TZ577 Card and received by Master Station.
(Data inputted by Master Station)
Output data
Data which is sent by Master Station and received by 2D
-TZ577 Card.
(Data outputted by Master Station)
Global control
A function which allows Class 1 Master Station to send an input/output data
synchronization command to Slave Stations.
Communication WDT
A watchdog timer established in the slave parameter at Master Station.
GSD file
An electronic file stating parameter settings at Slave Station. A data setting
software compliant with Master Station, which is used to establish slave parameter
settings.
