3-114 System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
Rules:
• The communications reference must correspond with that configured
in the CFC (address stage 1 at the address input).
• The local LSAP with the entry "remote LSAP" must correspond to the
remote transmitter.
• Remote addresses can be entered, defined, but then only telegrams
of the appropriately selected transmitter are received (access
protection!); or the value can be set to 255, and then the association is
open for all. Recommendation: A "broadcast receiver" association
should always be defined, as this is the only possibility to provide
access protection for broadcast applications.
• The remote LSAP can be edited, but is however not evaluated
(corresponds to the value 255).
• The maximum PDU length should only be changed if the client cannot
handle the specified length.
Features:
• SIMADYN D is server (transmitter)
• SIMADYN D initiates data transfer
• An association must be configured for each object which is to be
transmitted.
• A connection is not established between the communication partners;
transferred data is not acknowledged
Application:
• Process data, with SIMADYN D as transmitter.
