UINT
Diagnostic, 0x8000, to decode a
message, high byte (bit 14 … 8):
channel number, low byte
(bit 7 … 0) module number
(*) Object 100 (0x64) Instance 1 Attribute 6
The “DNS_i_Trmndia” attribute is set depending on the state of the node, i.e., it will
execute a diagnostic evaluation. However, this word only supplies valid data if bit 3
(counted up from 0) in “ProcessState” (Class 100, Instance 1, Attribute 5) is set. This
bit indicates that a new diagnostic message is available (see “ProcessState”
description).
The diagnostic evaluation is done by bit 15 in the “DNS_i_Trmndia” attribute.
There is a diagnostic error if bit 15 is set. The error is rectified if bit 15 is not set. As
long as at least one diagnostic error is present, the MS LED is flashing red. If there are
several diagnostic notifications at the same time, the next diagnostic notification is
output with every read out of this attribute. If DNS_i_Trmndia = 0, there are currently
no new diagnostic notifications. The MS LED only changes back to green after the last
diagnostic message has been read (if the diagnostic reason has been resolved).
