Data to be
transferred
over the bus
In addition to the event data transfer the SPA
bus allows reading of all input data (I-data),
setting values (S-data), information recorded in
the memory (V-data), and some other data of
the module. Further, part of the data can be
altered by commands given over the SPA bus.
All the data are available in channel 0.
Parameters can be changed only by opening a
password. The password is a value within the
range 1…999.
The password is opened by writing a value to the
communication parameter V160 and closed by
writing the value to parameter V161. The pass-
word is also closed when the auxiliary power
supply is switched off.
The password can be changed via the SPA bus or
with the push-buttons on the unit. When using
the SPA bus, the password must be opened. The
new password is written to parameter V161.
When using the push-buttons, the password is
changed in subregister 3 of register A, where the
old password is replaced by a new one.
If a wrong password is entered 7 times, the
password turns to zero, in which case it is no
longer possible to open it via the bus. Then the
password can be given a new value only by using
the push-buttons.
