HEI Configuration Block




This block was developed by Opal-RT to interface the T1H-EBC100 Ethernet Base Controller (ebc) from Host Engineering.

This block is used to configure the Host Engineering Interface (HEI) service. The first field is used to set the number of ebc required and the second is a list of their node's ids. The first field must be equal to the size of the list of the second parameter. Avoid setting an ebc id to 0. This id is reserved for online configuration through the Host Engineering software and may cause inappropriate behavior if not done correctly. Also, if there is two ebc with the same node id on the network, the initialization will fail. Make sure to configure your ebcs in consequence.


Ebc countSpecify the number of Ethernet Base Controllers.
Node listSpecify the ids of the Ethernet Base Controllers. The size of this list must be equal to the ebc count previously specified.


No inputs.


No outputs.

Characteristics and Limitations

Time Limitation

Step size supported without overrunning (processor 2.4 GHz): 30 µs

Notice: even though the model can run at 30 us, the relays themselves won't be updated that fast. The constructor documentation specified that a time delay of 15 ms in the worst case should be expected. All commands meanwhile will be ignored.
