3.21.3.5 System error message structure
A system error message has essentially the same structure as a
communications error message. The only differences are the "message
text" where the "system message" is always used, as well as the
message type ('S'). Further, a maximum of one system error message is
generated, which is identified during the initialization phase of the central
block.
As suffix, an ID is entered by the system error, which has the following
significance:
Value, suffix Significance
1 5 V power failure
2 15 V power failure
3 Software processing faulted
4
Error when accessing the L-bus communications buffer
memory
5
Error when accessing the C-bus communications buffer
memory
6 Error when accessing the standard periphery
7 Error when accessing the special periphery
8 Undefined L-bus access
9 Undefined C-bus access
10 (not used)
11 Hardware fault which cannot be identified
12 (not used)
13 Fault/error which cannot be identified
14
Fault message (ready internal) from the local expansion bus
(LE bus)
15 Error when accessing the local periphery (LP bus)
16 Overrun of the system bus controller

3.21.3.6 Detailed description of the message formats of function block
MSI
The description of the message formats consists of 3 parts:
• Assigning initialization inputs SNV, STM and SSF
• Basic format and maximum length of the message. This length
corresponds to the size of the channel logged-on by MSI.
• Net data structure which is required to initialize the channel.
