Remedy
1. Check whether the communication cable is
normal, and whether the shielded cable is
grounded.
2. Check whether the serial transmission speeds of
other devices on the network are the same.
3. Check whether the both ends of the cable are
connected to 121 Ω terminal resistors.
4. Supply power to AH10DNET-5A again.
Check whether the communication cable is normal,
and whether the network power supply is normal.
Supply power to AH10DNET-5A again. If the error still
occurs, please contact the factory.
Supply power to AH10DNET-5A again. If the error still

Supply power to AH10DNET-5A again. If the error still
occurs, please contact the factory.
1. Set the node ID of AH10DNET-5A again. The new
node ID can not be the same as the node ID of the
slave set in the scan list. Supply power to
AH10DNET-5A again.
2. Put no slave in the scan list, and download the
blank scan list to AH10DNET-5A through the
simulated online mode in the software. Supply
power to AH10DNET-5A again.
