IEC 60870-5-103
24
A private IEC 60870-5-103 definition can be entered for every REB500 signal in
this dialog. The "Set default" button is enabled for a signal in the public range of
the protocol so that the ABB default setting can be restored at any time.
The limitations specified in the standard must be observed when assigning
information numbers. The latter must be within the following ranges:
16-52; 73; 128-130; 64-72; 74-93

Disturbance recorder, binary signal transfer
Binary signals transmitted in disturbance records only have numbers and no
designation. The assignment of numbers to signal names is given in the
COMTRADE file <filename>.CFG, which can be uploaded, for example, from a
Bay Unit using HMI500.
Signal configuration instructions
Should the same logical signal be configured on two different BIO modules in a
Bay Unit, only one of them should be relayed to the IEC 60870-5-103 bus. A
configuration that is duplicated produces two indistinguishable events, which can
cause some confusion. The response is reflected by HMI500, which also generates
two events.
Cause of transmission
With the exception of 42 (generic writing command), all the possible causes of
transmission are supported in the command direction.
In the supervisory direction, they are all supported with the exception of 7 (test
mode), 12 (local HMI) and 44 (return confirmation of a generic write command).
Type identification
The type identification defines the type of ASDU that has been transferred.
