The event register can be read by the L com-
mand only once. Should a fault occur e.g. in
the data transfer, the B command can be used
to re-read the contents of the event register.
When required, the B command can be re-
peated. In general, the control data communi-
cator reads the event data and forwards the in-
formation to an output device continuously. The
control data communicator also resets abnor-
mal status data, so this data is normally a zero.
All settings allow reading and writing. However,
a condition for writing is that the remote set
password has been opened.
When settings are changed, the regulator mod-
ule checks that the given values are legal. If the
module is given a value outside the permitted
limits, either manually or by remote setting, the
module will not store the new value but retains
the previous one.
