Information
●
For loop topology, automatic termination is performed as soon as the actuator
is connected to the power supply.
●
In case of a power failure, the two RS-485 loop segments will be automatically
connected so that the actuators following these segments remain available.
●
Redundant loop topology may only be established when using a SIMA Master
Station.
