Example

Nine storage interfaces are registered. This means that 4 process data words are occupied. However, there is only one storage diagnostic bit in the 2nd and 4th while the 1st and 3rd are fully occupied.

INFORMATION

If a storage diagnostic interface is connected directly to the device (MDP92A/MDE90A) (e.g. an MDC90/MDC92), this storage unit occupies the first index. The other memory modules in the energy storage system are then shifted back by one position.

If, for example, there was an overtemperature error in the 5th storage module, an overvoltage in the 6th, and an overtemperature warning in the 9th, the process data interface would look as follows:
