another terminal, or in a station computer.
One usage for automatic programs is when the apparatuses are included in
a sequence, for example, a busbar transfer.

The command outputs from the apparatus control modules can be con-

The output module has supervised outputs. That is, the output relays are
continuously supervised in a way that an unwanted activation is detected,
which stops the continuation of the operation. This is performed by using
the ERROR signal connected to BLKCONL for blocking the command.
To get a secure command, two contacts are connected in serial. The fol-
