3.3.4 Details of the channel-related diagnostics

3-14
Explanation
Bit = 1: Master must fetch diagnostic data until this bit is
set to 0
Bit = 1: Bus node does not support the function requested
Bit = 1: Response monitoring/watchdog activated
Bit = 1: Freeze activated
Bit = 1: SYNC activated
Reserved
Bit = 0 (set by the bus node)
Explanation
Reserved
Bit = 1: Bus node has more diagnostic messages than can
be buffered or master includes more diagnostic messages
than it can buffer.
Through the channel-related diagnostics, detailed diagnostic
information is transferred by port. For each channel, 3 bytes
of diagnostic data are available (see Fig. 3/4):
– Byte 1: module number
– Byte 2: module type
– Byte 3: type of diagnostics
