coprocessor
the 1785-PFB/B PROFIBUS Coprocessor module
CRL
Communication Relationship List. In FMS, a CRL is a database within the station,
holding the description of all communication relationships of that station to all
other stations, independent of the time of use. For more information on CRLs,
refer to DIN 19245 Part 2: Process Field Bus.
default settings
values used for communication configuration data such as OD, CRL (for FMS)
DP slave database,and bus parameters whenever the coprocessor's working
RAM configuration is reinitialized.
defined connection
in FMS, a connection type that specifies both end nodes of the channel by giving
their network address and the FDL service access points (SAPs) used in both
nodes
diagnostics
three LED indicators located on the front panel of the coprocessor provide the
user with the status of the coprocessor and its communication channels. Also
referred to as
user interface
.
domain object
in FMS, represents a portion of the processor's memory image. In the
coprocessor, represents the processor's entire memory image.
DIN
Deutsches Institut fur Normung. The German Normalization Agency.
DP
Decentralized Periphery. A German/European standard (DIN 19245 Part 3) that
specifies a simplified user interface with PROFIBUS link layer services and
protocol to use with decentralized peripherals.
DP interface
a 9-pin female D-shell connector located at Port 2 on the front panel of the
coprocessor.
