Section 1: Optional Module 9: Profibus
The OM9 Profibus DPV1 interface is an electronic module that allows you to connect
the Bettis SCE300 electrical actuator to a Profibus DP network. The module has its own
microprocessor and control program. It works as a pure bus interface and does not affect
the actuator control integrity. It is installed inside the actuator housing and takes the
electrical power from the actuator power supply module.
The RS485 interface is located on the module board. The Profibus network is fully isolated
from the actuator electronics. The OM9 Profibus DPV1 is designed to support Profibus
DPV0 cyclic communication and acyclic communication as per Profibus DPV1 extension.
