ru30 SACB comm state
This 16 bit object displays the state of the communication of the control board with
the safety module (only F6-A and S6-A) with the power unit (from housing size 6 at
F6) and with the encoder interface.
This object can be used to evaluate errors ru01 = 41 "ERROR safety module
SACB comm.“, ru01 = 42 "ERROR power unit SACB comm.“ and ru01 = 43 "ER-
ROR enc.intf. SACB comm.”.
There are two special cases for the communication with the power unit: - For de-
vices up to housing size 5 there is no communication with the power unit, but the
plain texts for bits 8 ... 11 = 0 and bits 16 ... 19 = 0 are displayed. - For devices of
housing size 6, there is no communication with the power unit CPU2, but the plain
texts for bits 16… 19 = 0 are displayed.
In both cases the bits are not considered in the error evaluation, error ru01 = 42
"ERROR power unit SACB comm." is not triggered by this.
The meaning of the individual bits is defined as follows:
