of ASRTU-EC16AP1TA are consistent
with those configured on the software.
2. Check if the power supply and wiring of
the modules on the right of
ASRTU-EC16AP1TA are fine.
3. Check out the error information of the
modules on the right of
ASRTU-EC16AP1TA and then deal with
the errors by following the instructions in
corresponding module manuals.
4. Make sure that the connection of
EtherCAT cable is normal.
5. If the online upgrade of
ASRTU-EC16AP1TA’s firmware fails, you
can try to power it on again. If the
problem cannot be solved after you
repower it multiple times, contact local
