ctrlX SAFETY "SafeMotion"
Fig. 51: Safety bus communication
If discrete selection signals are to be evaluated in parallel with the Safety bus
communication, the corresponding bit in the predefined configuration of the
consumer connections can be masked via the parameter(P‑0‑3340.0.1). Due
to the masking, the IO mapper block can be freely configured again in the
corresponding network. Thus, other signals can be processed in the network.
The function block type "Safe connector" (or "binary-to-bit decoder" for binarily
coded signals) is permanently assigned to all networks that are not masked via
P-0-3340.0.1.
Binary-coded signals have to be masked completely. It is not allowed to mask
individual bits in this case!
Depending on the active predefined configuration, the data for the pro-
ducer connection are copied from the corresponding status parameters for
encoder evaluation (P-0-3256) and for the "Safe Motion" profile (P-0-3231 and
P-0-3237), and are transmitted directly to the corresponding bit in P-0-3341.
9.4.3 Configuring the consumer and producer connection
Introduction
For the Safety bus communication, 2 predefined configurations for the con-
sumer connection and 2 predefined configurations for the producer connection
have been defined. A predefined configuration defines the signal assembly to
be transmitted using the Safety bus communication and their default connec-
tion via target and/or source parameters with the SafeMotion profile. The pos-
sible predefined configurations are made available to the control unit via the
device data sheet.
