The MP-V controller is a multi-purpose, fully programmable, IP based field controller dedicated for VAV applications. MP-V integrates a controller, a damper actuator, and an air flow sensor in a single unit for ease of installation. The MP-V can either be used as a standalone BACnet field controller or as part of an EcoStruxure BMS with an automation server or Enterprise Server as the parent server. MP-V can also be reconfigured through the EcoStruxure Building Operation software to use BACnet MS/TP, instead of BACnet/IP.

MP-V allows for flexible control solutions due to the dual Ethernet ports, the interface to SpaceLogic Sensor devices, and the mix of universal inputs, triac outputs, and analog outputs.

When MP-Vs are part of an EcoStruxure BMS, you can take full advantage of the existing EcoStruxure Building Operation engineering tools.

MP-V Models

The MP-V comes in two models with a different I/O point count and different I/O point mix.

For more information, see MP-V Models .

MP-V Onboard I/O

The MP-V models offer a versatile mix of I/O point types that match a wide variety of VAV applications.

For more information, see MP-V Onboard I/O .

MP-V Damper Actuator

The MP-V has an integrated damper actuator, which allows for simplified installation of MP-V directly over the damper shaft.

For more information, see Damper Actuator .

MP-V Air Flow Sensor

The MP-V uses a digital pressure sensor to measure the air velocity pressure signal from the velocity probe in the inlet of the VAV box. The measured value is used by the controller to position the VAV damper actuator for the required air flow.

For more information, see Air Flow Sensor .

MP-V Built-in Power Supply

The MP-V has a built-in power supply designed to accommodate 24 VAC at 50/60 Hz input power.

For more information, see MP-V Built-in Power Supply .

BACnet/IP Device Memory

BACnet/IP devices have three types of memory:

  • Flash memory: for boot loader, operating system, application software, and configuration storage

  • RAM: for runtime operation

  • FRAM non-volatile memory: for data retention in the case of power outage

For more information, see Memory in RP and MP Controllers and I/O Modules .

BACnet/IP Controller Supported Building Standards

One of the cornerstones of the EcoStruxure BMS is support for open standards. As a result, the BACnet/IP controller complies with the BACnet open standard, one of the most popular standards for buildings.

For more information, see RP and MP Controller Supported Building Standards .

MP-V Communication Ports

The MP-V provides the following combination of communication ports:

  • Two Ethernet ports

  • Two USB ports

  • One RS-485 port

For more information, see MP-V Communication Ports .

MP-V Sensor Bus

The MP-V sensor bus allows SpaceLogic Sensor devices to be connected to the controller.

For more information, see MP-V Sensor Bus .

MP-V Modbus

The MP controller Modbus RTU (RS-485) subnetwork allows standard Modbus devices to be connected to the controller. An adapter is required for converting the controller RS-485 Com port with RJ45 interface to screw terminals.

For more information, see MP-V Modbus .

MP-V BACnet MS/TP Support

The MP-V controllers can be reconfigured to communicate with the hosting server based on the BACnet MS/TP protocol, instead of the BACnet/IP protocol. An adapter is required for converting the controller RS-485 Com port with RJ45 interface to screw terminals.

For more information, see MP-V BACnet MS/TP Support .

MP-V Screw Terminals

The MP-V is delivered with terminal blocks installed on the device. The MP-V uses pluggable terminal blocks, which are easy to install and remove from the device.

For more information, see MP-V Screw Terminals .

MP-V Controller LEDs

There are five LEDs on the front panel of the MP-V controller.

For more information, see MP-V Controller LEDs .

MP Controller Reset Modes

You can reset and restart the MP controllers in different ways depending on how long you press the reset button. The resets and restarts can affect the retention of values after restart based on the retain levels configured for the variables.

For more information, see MP Controller Reset Modes .

MP-V Device Installation

The MP-V incorporates an integral actuator and the device is designed for over-the-shaft damper installation.

For more information, see MP-V Device Installation .

Wiring

The wiring recommendations provide guidance regarding wiring of the Central IO modules, automation servers, BACnet/IP devices, RP controller expansion modules, and Operator Display.

For more information, see Wiring .

BACnet/IP Device Firmware Management

Using WorkStation, you can update the firmware of multiple BACnet/IP devices and their attached SpaceLogic Sensor devices at the same time with minimum downtime. In particular, the universal upgrade package simplifies the update process and requires minimal user involvement and coordination.

Tip:

SpaceLogic Sensor devices are supported by the BACnet/IP controllers - MP and RP controllers.

For more information, see BACnet/IP Device Firmware Management .
