Communications configuring
System- and communication configuring D7-SYS - SIMADYN D 3-131
Edition 12.2003
3.9 DUST2 coupling
To output messages from a message system, printers can only be
connected to SIMADYN D which can handle the serial communications
protocol X-ON/X-OFF with additional telegram block check characters
(ETX/ACK).
3.9.1 Hardware structure
The following hardware is required for the DUST2 coupling:
• CS7 communications module with SS4 communications module
The SC56 cable can be used to connect a printer to the communications
module CS7 with communications module SS4 if an appropriate adapter
is used. This adapter converts a 25-pin high-density connector into a 25-
pin sub-D socket connector.
The printer must be equipped with the matching interface module, which
is parameterized for the settings configured with SIMADYN D (e. g. baud
rate, parity).
Further information
on the printer, refer to the printer Manual.
• Printer DR 215-N is used as message printer.
(Refer to Catalog IC40 from AUT and SIMADYN D Info 94/14)
3.9.2 Configuring
As the DUST2 protocol operates according to the "point-to-point"
principle, and a message printer can only be handled as communications
partner, to output messages, a transmit address is not required (when
using CS7/SS4, only a channel name should be specified at the
corresponding output block; address stages 1 and 2 are not used).
A central coupling block is available to configure the DUST2 coupling and
to set the format for printer output:
• @CSD02: For a coupling via CS7/SS4
The DUST2 central coupling block is used to initialize the
communications interface (hardware driver and DUST2 software). In
addition, it can configure the protocol (minimum) with the following I/O
(connections):
• PAR (parity)
This specifies the parity in the telegram characters
(0 = even, or 1 = odd number of ones)
