Possible causes
F130:
Anybus Access Fault
It is the alarm that indicates access error to the
Anybus-CC communication module.
It actuates when the SSW cannot exchange data with
the Anybus-CC accessory, when the Anybus module
identifies some internal fault, or when there is a hard-
ware incompatibility.
In order to remove this fault, it is necessary to power
the SSW off and on again.
- Check that the accessory is properly fitted.
- Check that the equipment firmware version supports
the Anybus accessory.
- Hardware errors due to improper handling or instal-
lation of the accessory, for example, may cause this
error.
- If possible, carry out tests by replacing the commu-
nication accessory.
F131/A131:
Anybus Modbus TCP
Timeout
It indicates fault in the Modbus TCP communication
for Anybus-CC accessory.
It occurs when the equipment stopped receiving valid
write requests to the Slot Command Word or Data
Write Words for a period longer than the programmed
(C8.4.9).
The time counting starts as soon as it receives the first
valid write request.
- Check network installation,
broken cable or
fault/poor contact on the connections with the net-
work, grounding.
- Make sure that the Modbus TCP client sends tele-
grams to the equipment in intervals shorter than the
programmed (C8.4.9).
