Hobart - What is the Hobart Ground Power Modbus and BACnet and HTML Gateway
CAS-2700-01
Hobart Ground Power
Modbus and BACnet and HTML Gateway
Description
The HOBART Ground Power Serial Driver allows the Gateway to poll Hobart devices for status, real time and configuration data. Thus the driver can be used to read current, voltage, phase, power and other variables from the Hobart device.
The Hobart Ground Power (HGP) Gateway serves data from a HGP controller as Modbus, BACnet or Web data. The gateway supports all these options simultaneously. Use the data you want and ignore the other.
The Gateway connects to the HGP controller, reads data and stores it internally. When a remote system requests data, this data is served in a form that is appropriate to the protocol. In the event that the connection to the HGP controller is lost, or data cannot be read, the gateway can signal this to the remote data client.
The gateway requires minimal configuration and can be considered a plug and play component of a system, in that it is ready to operate out of the box with the default configuration.
The driver is a serial driver using a RS232 serial port to connect between the Gateway and the HOBART unit.

Connection configurations
Driver Operation
The driver can be configured to execute any of the commands in the 'supported function' list. The data sent is stored internally in the Gateway and is made available to other protocols (Modbus, BACnet and HTML).
The frequency with each data point is read is configurable. The driver retries on errors or timeouts. If the data cannot be read then after some configurable time it is marked as out of service.
Communications functions
Supported functions.
Not all Hobart communication functions are supported. Most that report status info are provided. Those used to configure the unit are not included. Please review this list in determining whether this driver is fit for your purpose.
