3-234 System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
• 99
Address stage 2 = 99 signifies a broadcast address (refer to Chapter
USS master coupling)
NOTE
• A maximum of the first 56 characters of the message text are output
at the OP2.
• For messages with value, a maximum of the first 28 characters are
output. A longer message text will be cut-off.
The MSI message output block must be configured to output messages.
In this case, connections SSF (submit standard format), SNV (submit
message number value) and STM (submit text for messages) must be
configured as follows:
Possible data entries at connections SSF, SNV, STM of the message output block MSI:
SSF
(hex
format
SNV
(prefix/suffix)
STM
(text)
Evaluation and output at the OP2:
0 0 1 Message, only with text: This is always output at the OP2 (with text).
0 1 1
Message with prefix/suffix and with text: The prefix is evaluated as
message class. If the message class is permissible, the message is
output with text. Otherwise, it is rejected.
0 1 0
Message without text: The prefix is evaluated as message class. If the
message class is permissible, the message is output with prefix/suffix.
Otherwise, the message is rejected.
0 0 0 (illegal combination; message is rejected)
Table 3-71 Possible data entries at connections SSF, SNV, STM of the message output block MSI
The message class (prefix) of a message is configured at the message
acquisition blocks (connection RP) (refer to the Chapter Communications
utility, message system).
The permissible message classes for an OP2 are locally configured at
the OP2
Further information
on the OP2 operator control device, refer to the User Documentation
"SIMADYN D, hardware description".
3.20.4 Application information
The "DIS" function blocks are structured, so that they operate together
within an optimized time frame. The configuring rules (all function blocks
in the same sampling time) guarantee that the processing steps are
executed in precisely the correct sequence within one sampling time:
