Data to be
transferred over
the serial bus
In addition to the event codes input data (I data),
output data (O data), setting values (S data)
memorized data (V data), and some other data
can be read from the module over the serial bus.
The values of parameters marked with the letter
W can be changed over the SPA bus.
When a setting value is changed, either via the
push-buttons on the front panel or over the
serial bus, the relay module checks whether the
given parameter value is legal. A value outside
the permitted setting range will not be memo-
rized, but the previous setting will be retained.
To be able to change a setting parameter over the
serial bus a password in the range 1..999 is
required. The default setting is 1.
The password is opened by giving the serial
communication parameter V160 the desired
numerical value. Parameter V161 is used for
closing the password. The password is also closed
by failures in the voltage supply.
The push-buttons of the relay module or a
command over the serial bus can be used to
change the password. To be able to change the
password over the serial bus, the password first
has to be opened. The new password is entered
via parameter V161. When using the push-
buttons, the new password is written in the place
of the old one in subregister 3 of register A.
Should the wrong password be given 7 succes-
sive times, it turns into a zero and can no longer
be opened over the serial bus. Then the pass-
word can be given a new numerical value via the
push-buttons only.
R = data to be read from the module
W = data to be written to the module
