Limitorque MX DeviceNet Field Unit 2 System Components 2.1 Introduction FCD LMENIM2328-00 – 11/05 This section gives an overview of the components used in the DeviceNet system. The field unit is installed in each MX actuator. The network cable connects the field unit to the network via the actuator terminal block. The network cable is connected to a host controller, typically a PLC. 2.
Limitorque MX DeviceNet Field Unit FCD LMENIM2328-00 – 11/05 The MX features include: • Non-intrusive setup • Separately sealed terminal chamber • Patented absolute encoder for valve position sensing (no battery required) • 32-character LCD for indication and calibration with configuration permitted in six languages. • Sophisticated electronic control, monitoring, and diagnostic capabilities with patented LimiGard™ technology 2.2.
Limitorque MX DeviceNet Field Unit 2.2.3 FCD LMENIM2328-00 – 11/05 Hardware interface The DeviceNet Limitorque Interface is comprised of a minimum of one PCB with two interfaces - One for the DeviceNet Terminal Block connector and one for the SMT Main Board. Figure 2.3 gives an overview about the hardware. The microcontroller on the DeviceNet Limitorque Interface handles the DeviceNet protocol, stores the DeviceNet parameters in an EEPROM, and communicates with the SMT Main Board via SPI. Figure 2.
