AddMe® Lite AMJR-14-SB Programmable I/O for BACnet MS/TP

Control Solutions’ AddMe Lite features 12 inputs which accept analog input from thermistors or 0-10V sensors, or discrete input from dry contact switches. AddMe Lite also provides 2 discrete outputs which can sink 1A at 24VDC.

Analog Input objects provide data from the analog I/O points. Linearization tables are provided for 10K and 20K type II, III, and IV thermistors. Input type and scaling is configured by writing to object properties. Binary Output objects provide BACnet access to the outputs. An additional 60 writeable Multistate Input objects are available for use by the user's program.

The AMJR-14-SB configuration tool connects to the MS/TP network using the MTX002 MS/TP to USB adapter (if not using a BACnet IP router). This intelligent adapter plugs into your PC's USB port, and offloads the MS/TP token passing from the PC to make it more reliable. The MTX002 allows you to connect your PC to an MS/TP network running at 76800 baud, something not possible with a generic RS-485 port adapter.

The MTX002 functions as an MS/TP device itself. The combination of the MTX002 and configuration tool running on your PC will appear on the network as a discoverable BACnet device. The diagnostic section in the configuration tool can be used to read and write any objects in any MS/TP device on the network. The configuration tool provides a template for reading and writing the multiple properties per BACnet object that define its configuration or client/server mapping. All configuration parameters exist as properties of BACnet objects which are accessible to any BACnet client. The Control Solutions configuration tool simpy provides a user friendly template for accessing those properties.

The AMJR-14-SB Configuration Tool is a user friendly configuration tool that provides a simple template for assigning the BACnet object properties that configure the device. Connect the AMJR-14-SB to your laptop via a USB to MS/TP adapter (MTX002) or via a BACnet IP router.

i.CanDrawIt® is available at no additional cost for use with AddMe Lite controllers from Control Solutions. i.CanDrawIt® works just like an electrical schematic CAD program, except you draw control programs that look like circuits. The resulting software will function like the circuit you draw. i.CanDrawIt® includes visual program simulation as well as visual live debugging where supported by the target device. Set breakpoints or step through the program one visual function block at a time. Update variables and I/O objects in simulation or live.
