System- and communication configuring D7-SYS - SIMADYN D

Edition 12.2003
The name of the message system is ”MELD”. This name is configured at
all CMS connections of the message blocks. The message buffer can
accommodate 30 messages (connection NOM at @MSC), is located in a
volatile RAM (connection SAV at @MSC) and is enabled for message
entries (connection MUN at @MSC).
Generated messages can be assigned to blocks using the RP- and RRS
connections, whereby each block of the message system has at least
one RP connection. Proceed as follows:
•
Prefix 0
Designates a message which is generated by @MSC
(communications- and system error messages). Thus, connection RP
of @MSC is assigned the value 0. @MSC automatically generates the
suffix, depending on the message type.
•
Prefix 1
Designates a message, which is generated by MSI (overflow
messages). Thus, MSI assigns a value of 1 to connection RP. MSI
automatically generates the suffix (number of messages which have
overflowed).
•
Prefix 2
Designates a message which was generated by MSIPRI.
•
Prefix 3
Designates a message, which was generated from a message block
(MER or MERF0). Thus, connection REP of MER and MERF0 is
assigned the value 3. The suffix is not automatically generated as for
the other blocks. In this case, the connections are available, at which
the suffix can be configured. 33 various messages are generated in
the example (1 MER message, 16 activated messages MERF0,
16 de-activated messages MERF0), which are numbered from 0 - 32:
−
The message of block MER is assigned suffix 0 (RS connection
MER).
−
The 16 activated messages of block MERF0 are assigned suffix
1-16 (RS1 connection MERF0).
−
The 16 de-activated messages of block MERF0 are assigned suffix
17-32 (RS2 connection MERF0).
•
Suffix
For block MERF0, for the suffix a basis value is specified. The bit
number of the message-generating bits of message signal vector IS1
is added to this basis value.
Using a prefix and suffix, it is not only possible to uniquely assign the
messages to the generating blocks, but it is also possible to functionally
combine the messages. In the configuring example, the MER and
MERF0 blocks generate messages with the same prefix, which indicates
a logical association.
