Control Solutions’ ValuPoint IV features 14 universal inputs which are context sensitive. 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 8-bit resolution at high speed for fast response. All I/O points are accessed as BACnet objects.

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 5kHz is available on 2 channels in all modes. If analog inputs are sampled in 10-bit mode, pulse input to 20Hz is available on all channels. Pulse counts are totalizing, and saved to non-volatile memory every 15 minutes.

The ValuPoint® series of BACnet controllers is designed to be a building block in a distributed control system where controllers communicate peer to peer via BACnet MS/TP. Each ValuPoint controller can access BACnet objects in other BACnet devices, both ValuPoint® BACnet controllers and other manufacturer’s devices. Remote objects are mapped to local objects that mirror the value of the remote object. Access to the remote objects can be via periodic polling, or COV subscription. The ValuPoint controller will subscribe to COV’s in other devices where available, or do periodic polling. At the same time, other devices can subscribe to COV’s in the ValuPoint controller.

All of the ValuPoint® features available to local objects are also available to the remote mapped objects. This means the remote objects can be incorporated into the local i.CanDrawIt® program, and also be monitored by local alarms. This means the remote objects can be included in data logging as well. Data logging is enabled on a point by point basis so that data logging capacity is allocated where needed.

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 250 read/write objects. Object types include analog, binary, and multi-state variations of input, commandable output, and writeable value.
