Irisys People Counter Gateway

The Irisys People Counter to BACnet IP, Modbus or Web Gateway acts as a protocol converter. It allows Irisys People Counter devices to communicate with devices on a BACnet IP or Modbus Networks or directly to web.
The Irisys people counter gateway can connect to one or more Irisys people counter devices and reads the current occupancy data from the device.
The Web (HTTP, XML, REST, Json, MQTT) driver allows the Gateway to push data to the Web via a variety of Protocols.
The Modbus TCP driver allows the Gateway to transfer data to and from devices over Ethernet TCP/IP using the Modbus protocol.
The Modbus RTU driver allows the Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.
The BACnet IP Driver allows the Gateway to transfer data to and from devices over Ethernet UDP/IP using the BACnet IP protocol.

CAS Hardware 700

The CAS 700 Hardware device contains 2 9-pin serial ports (1x RS485 and 1xRS232), and one Ethernet port. The device also contains a microSD card where system files, assets, configurations, and logs are stored.

The device has the following system drivers that can be enabled:

  • HTTP REST Server - a passive web server with an API that users can interact with the device to get or set values
  • HTTP Push Driver - a driver that can be configured to push data in a specific format (JSON, XML, CSV) to a 3rd party web server. Current data formats are Chipkin's default JSON payload and VeederRoot Tank data as JSON. Please contact Chipkin for information on adding additional formats.

Irisys People Counter Driver

The Irisys people counter gateway can connect to one or more Irisys people counter devices and reads the current occupancy data from the device.

The occupancy read by various other protocols including BACnet IP, Modbus TCP, Modbus RTU or web protocols. The gateway supports all these options simultaneously. Use the data you want and ignore the other.

The Gateway requires minimal configuration and can be considered a plug and play component of a system. 

A series of BACnet objects will be created when a new sensor to the CAS Gateway.

  • device: 389001 (PeopleCounter)
    • analog_input: 1 (West Building - Occupancy)
    • analog_input: 2 (West Building:Ground floor - Occupancy)
    • analog_input: 3 (West Building:Ground floor:Main Entrance - Count In)
    • analog_input: 4 (West Building:Ground floor:Main Entrance - Count Out)
    • analog_input: 5 (West Building:Ground floor:Main Entrance - Occupancy)
    • analog_input: 6 (West Building:Ground floor:Main Entrance - Normalized Occupancy)
    • analog_input: 7 (West Building:Ground floor:Main Entrance - Device In)
    • analog_input: 8 (West Building:Ground floor:Main Entrance - Device Out)
    • analog_input: 9 (West Building:Ground floor:Main Entrance - Reset)

Each building will have its own BACnet Occupancy object that is a sum of all the floors's Occupancy.

Each floor will have its own BACnet Occupancy object that is a sum of all the sensor’s occupancy values on that floor.

Each sensor will have several objects created

  • Count In – The change in {device in} since the last reset hour.
  • Count Out – The change in {device out} since the last reset hour.
  • Occupancy – The difference between {count in} and {count out}
  • Normalized Occupancy – The difference between {count in} and {count out} using the slope algorithm.
  • Device In – The raw values read from the people counter device for the in line.
  • Device Out – The raw values read from the people counter device for the out line.
  • Reset – The difference between {Device in} and {Device out} at the time of the reset hour.

Web (HTTP, XML, REST, Json, MQTT) Driver

The Web Diver allows for data to be monitored by remote systems running applications that can issue HTTP or SOAP/XML GET requests – such applications can be easily developed by end users. Of course, this data is available using an Internet Browser such as Internet Explorer or Google Chrome

Modbus TCP Driver

The CAS Modbus TCP driver allows the CAS Gateway to transfer data to and from devices over Ethernet TCP/IP using the Modbus protocol.  The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.

The CAS Modbus TCP Driver supports the following Modbus Functions:

- 01 (0x01) Read Coils - 05 (0x05) Write Single Coil
- 02 (0x02) Read Discrete Inputs- 06 (0x06) Write Single Register
- 03 (0x03) Read Holding Registers    - 15 (0x0F) Write Multiple Coils
- 04 (0x04) Read Input Registers- 16 (0x10) Write Multiple Registers

Modbus RTU Driver

The CAS Modbus RTU driver allows the CAS Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.  The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.

The CAS Modbus RTU Driver supports the following Modbus Functions:

- 01 (0x01) Read Coils- 05 (0x05) Write Single Coil
- 02 (0x02) Read Discrete Inputs- 06 (0x06) Write Single Register
- 03 (0x03) Read Holding Registers- 15 (0x0F) Write Multiple Coils
- 04 (0x04) Read Input Registers- 16 (0x10) Write Multiple Registers

BACnet IP Driver

The CAS BACnet IP driver allows the CAS Gateway to transfer data to and from devices over Ethernet UDP/IP using the BACnet IP protocol.  The CAS Gateway can either be a Client, reading and storing values from a BACnet device, or a Server, making data available as BACnet objects.

The CAS BACnet IP Driver supports the following BACnet Services:

- Who-Is- Who-Has
- Read Property- Read Property Multiple
- Write Property- Write Property Multiple
- Subscribe COV     - Time Synchronization

Note: Chipkin is always updating the BACnet IP Driver. For a recent list of supported services, please visit www.chipkin.com or contact us. If there are services that you require that are not listed, please contact us to discuss how we can add them to the driver.
