Limitorque MX DeviceNet Field Unit FCD LMENIM2328-00 – 11/05

flowserve.com

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

2.2.2 DeviceNet Field Unit

The DeviceNet field unit is installed in the MX controls compartment. This unit permits the actuator to
be controlled by a host controller, typically a PLC, via the DeviceNet network. The DNFU includes two
high-level, surge-protected, and isolated network communication channels, configurable digital I/O, and
configuration via LCD screen. The following commands and information may be transmitted over the
DeviceNet network:

“OPEN,” “STOP,” and “CLOSE” commands
“ESD” and “MOVE–TO” position commands
Actuator status and alarm messages
Six digital inputs and two analog inputs for user
A surge-protected and isolated communication channels
MX control panel configuration
Torque output (for reference only) and position feedback
Four digital outputs (standard)
