R = Data which can be read from the unit

The data transfer codes L, B, C and T have been
reserved for the event data transfer between the
module and the station level data communica-
tor.
The event register can be read by the L com-
mand only once. Should a fault occur e.g. in the
data transmission, it is possible, by using the B
command, to re-read the contents of the event
register once read by means of the L command.
When required, the B command can be re-
peated.
