ValuPoint® VP4-2370 Smart I/O for BACnet IP

Control Solutions’ Model VP4-2370 ValuPoint® Smart I/O for BACnet IP is a BACnet Application Specific Controller (B-ASC) that includes programmable control. The 4th generation ValuPoint® platform is designed to be a building block in a distributed control system where controllers communicate peer to peer via BACnet IP.

The ValuPoint® Model VP4-2370 features 14 universal context sensitive inputs. When configured as an analog input, the continuously self-calibrating sigma-delta converter produces 15-bit resolution with high noise immunity. When configured as a discrete input, the converter switches to 10-bit resolution at 1,000 samples per second for fast response.

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. Analog and Binary Output objects provide BACnet access to the outputs.

Pulse input at up to 1kHz is available on 2 channels in all modes. If analog inputs are sampled in fast 10-bit mode, pulse input to 10Hz is available on all channels. Pulse counts are totalizing, and saved to non-volatile memory every 15 minutes.

ValuPoint Model VP4-2370 also includes 3 analog 4-20mA outputs, and 6 Form A relay outputs. All I/O points are accessed as BACnet objects.

The user has the ability to assign object allocation as part of setup of the controller. Resources are allocated from a common pool, and the user has the ability to decrease the number of one type of object in order to increase the number of another type. Total object count will range from approximately 100 commandable objects (with full priority array) to 200 read/write objects. Object types include analog, binary, and multi-state variations of input, commandable output, and writeable value.

ValuPoint® support software, available for download at no cost, includes the VP4-2370 configuration tool, i.CanDrawIt graphical programming tool, and the pliWrite line programming tool. Both programming tools support both simulated execution and live debug. The tools connect to BACnet IP directly via your Ethernet network.

The ValuPoint VP4-2370 Configuration Tool is a user friendly configuration tool that provides simple templates for assigning the BACnet object properties that configure the device.

i.CanDrawIt® is included at no additional cost with every ValuPoint® controller 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.
