Fieldbus control 299
Diagnostics – EFB
Fault queue for drive diagnostics
For general ACS320 diagnostics information, see section
. The three most
recent ACS320 faults are reported to the fieldbus as defined below.
Serial communication diagnostics
Network problems can be caused by multiple sources. Some of these sources are:
• Loose connections
• Incorrect wiring (including swapped wires)
• Bad grounding
• Duplicate station numbers
• Incorrect setup of drives or other devices on the network
The major diagnostic features for fault tracing on an EFB network include
parameters
. Section
describes these
parameters in detail.
Diagnostic situations
The sub-sections below describe various diagnostic situations – the problem
symptoms and corrective actions.
Normal operation
During normal network operation,
…
parameter values act as follows at
each drive:
•
advances (advances for each application message
properly received and addressed to this drive).
•
does not advance at all (advances when an invalid
message CRC is received).
•
does not advance at all (advances when character
format errors are detected, such as parity or framing errors).
•
value varies depending on network traffic.
• BACnet protocol: 5316 EFB PAR 16 (MS/TP token counter) advances for each
token passed to this drive. (Does not apply for other protocols.)
