Selection of the modules
The 3WA circuit breaker has a modular design and can be configured individually in the
project.
• The "3WA status and control" module has the fixed position of slot 1, subslot 1 in the
circuit breaker and is plugged in automatically.
• The "3WA status and control" module contains two input bytes for the binary status
information and two output bytes for control of the circuit breaker.
• If control of the circuit breaker is not required in the system, the "3WA status and control"
module can be replaced with the "3WA status" module. Please note that slot 1 must
always be occupied.
Both the control and the control bytes are implemented according to the LVSG profile of
the PNO (PROFINET user organization).
