The MP-C controller is a multi-purpose, fully programmable, IP based field controller. The MP-C models offer a flexible mix of I/O point types that suits a wide range of HVAC applications. MP-C is a native SpaceLogic device, which can either be used as a standalone BACnet/IP field controller or as part of an EcoStruxure BMS with a AS-P or AS-B server, or an Enterprise Server, as the parent server.

MP-C allows for flexible control solutions due to the dual Ethernet ports, the interface to SpaceLogic Sensor devices, and the versatile mix of universal inputs/outputs, triac outputs, relay outputs, and high power relay outputs.

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

The MP-C can be installed on a DIN rail or other flat surface inside a cabinet.

All MP-C models can be equipped with MP-C Display, which is an optional add-on module for output override. The MP-C Display can also be used to view and locally configure inputs and outputs.

MP-C Models

The MP-C comes in five models with different I/O point count and different I/O point mix.

For more information, see MP-C Models .

MP-C Onboard I/O

The MP-C models offer a versatile mix of I/O point types that match a wide variety of applications. Most of the I/O points are universal inputs/outputs, which are highly flexible and can be configured as either inputs or outputs.

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

Output Override Function (Optional)

The output override function allows you to manually override outputs. This function can be used for testing, commissioning, and maintenance of equipment.

For more information, see Output Override Function .

MP-C Built-in Power Supply

The MP-C has a built-in power supply designed to accommodate 24 VAC at 50/60 Hz or 24 to 30 VDC input power.

For more information, see MP-C 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 BACnet/IP Controller Device Memory .

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 BACnet/IP controller Supported Building Standards .

MP Controller Communication Ports

The MP controller contains a combination of Ethernet, USB, and SpaceLogic Sensor communication ports.

For more information, see MP Controller Communication Ports .

BACnet/IP Controller Sensor Bus

The BACnet/IP controller provides a sensor bus, which allows SpaceLogic Sensor devices to be connected to the controller.

For more information, see MP Controller Sensor Bus .

MP-C Screw Terminals

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

For more information, see MP-C Screw Terminals .

MP Controller LEDs

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

For more information, see MP 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-C Device Installation

The MP-C can be installed on a DIN rail or other flat surface inside a cabinet. The device is recommended to be installed in a cabinet, unless local regulations allow an exception.

For more information, see MP-C 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 .
