PROFIBUS DP-V0 Slave Interface (a complete set of products)
PROFIBUS DP-V0 Slave Interface Card (TZ577)
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.
Equipment which exchanges input/output data with Slave Stations.
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.
A lower-level station which communicates with Master Station.
A device which provides a link between the segments of a PROFIBUS DP network.
Resistor connected to the individual segments of a PROFIBUS DP network at each
end. Actually, terminator resistors built in the connector used with a PROFIBUS
network are enabled to fulfill intended purposes.
Slave station parameter established by Master Station. Items of parameter
information are stated on a GSD file.
A number assigned to Master Station or Slave Station. Numbering is in the range of
0 to 125.
Information about input/output configuration at Slave Station.
Data which is sent by 2D-TZ577 Card and received by Master Station.
(Data inputted by Master Station)
Data which is sent by Master Station and received by 2D-TZ577 Card.
(Data outputted by Master Station)
A function which allows Class 1 Master Station to send an input/output data
synchronization command to Slave Stations.
A watchdog timer established in the slave parameter at Master Station.
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.
