1. Switch the power supply of the rack off and on again.
2. Repeat the load operation.
If the CP responds to the download start, but the download operation does not finish properly,
it could be that:
● The same address has been assigned more than once on the plant bus.
● The load on the plant bus is too high.
Note
If a CP does not respond to a load procedure via the configured MAC address, load the CP
again via the imprinted address.
