6/6 Landis & Staefa Division
Dial-up communication with the VISONIK BPS occurs via the BPS's interface
COM1/TTY1 and a modem. It comprises the following functions:
•
Establish and terminate connections
•
Signal events
•
Collect operating data
•
Transmit process data
•
Operation
The VISONIK devices shown below can be used as dial-up communication partners for
an autonomous BPS. In applications, two devices can be defined in the BPS as partner
1 and partner 2, for example, DCS and teleterminal:
COM1/TTY1
DCS
BPS ECU
T+T
BPS
8884Z06E
Partner 1
of BPS
Partner 2
of BPS
Teleprinter
Teleterminal
These are the dial-up communication partners of a VISONIK BPS:
Partner Interpretation
DCS Data and Communication Server of a local VISONIK system. The DCS
may be used for a separate BPS as:
– own DCS with BPS process image or
– foreign DCS without BPS process image
ECU Enhanced Communication Unit of a separate SDLC ring with several
process stations. The ECU, for instance, connects the stations with a
higher DCS.
BPS Another autonomous BPS
Teleterminal PC with VISOTOOL Editor for remote BPS operation and monitoring
Teleprinter Separate printer for BPS alarm and error messages
Dial-up communication must be set up in all partners. In the BPS, this is done by:
– configuring the dial-up communication parameters
– defining the message types
– making entries in the text catalogues
