How to deal with
E5
The extension rack error or
the extension rack does not
exist.
1. Check if the extension rack is connected
correctly.
2. Check if the extension rack is consistent with
the configuration.
E6
The data configuration length
exceeds the allowed
maximum 500 words
Check if the configured modules on the rack are
so many that the configured data length exceeds
the maximum 500 words.
E7
AHRTU-DNET-5A is detecting
if the node address is
duplicate with that of other
device on the network.
If the code is shown for long, please treat the
error by the following means.
1. Ensure that at least two nodes work on the
network.
2. Check if the two ends of the network have
been connected with a 121 Ω resistor
respectively.
3. Check if the baud rate of the node
equipment on the network is the same.
4. Check if the communication cable is
abnormal, e.g. loose or cut.
5. Check if the communication cable exceeds
the maximum transmission distance. If it
does, the system can not be kept stable.
6. Check if the shielded wire has been
grounded.
7. Repower AHRTU-DNET-5A.
E8
A timeout occurs when
AHRTU-DNET-5A exchanges
data with the I/O module.
Check if AHRTU-DNET-5A and the I/O module
are running normally.
E9
The number of AH10SCM-5A
module exceeds the
maximum.
Reduce the quantity of the AH10SCM-5A
module, which should be no more than 8.
80
AHRTU-DNET-5A is in STOP
state.
1. Turn the switch RUN/STOP to RUN.
2. Check if the control word of
AHRTU-DNET-5A is 1. See section 4.1 for
details.
83
Downloading the I/O data
configuration in the software
Wait until downloading the configuration data of
AHRTU-DNET-5A is completed.
84
Downloading the data
configuration of AH10SCM-5A
serial port in the software
Wait until downloading the serial port
configuration data of AH10SCM-5A is completed.
