‘MicroSTAR’ Serial Driver
This driver is used to exchange data between a FieldServer and a ‘MicroSTAR’ devices. They are also commonly known as ‘Barrington MicroSTAR’ devices.
Each device has 4x AO, 4x AI, 4x DI, 4x DO and 4x Counters. The devices can be daisy chained on a RS485 network.
The driver can monitor the status of these points and write to the outputs.
This is an active client driver. The FieldServer is the client. The MicroSTAR devices are the passive servers. The Client sends messages and processes responses from the MicroSTAR’s.
The driver is a serial driver using a RS232 / RS485 serial ports to connect between the FieldServer and the MicroSTAR’s. If RS232 ports are used then a converter to RS485 must be used.
The driver is fully compatible with other FieldServer drivers and meets FieldServer’s quality assurance standards. The driver was developed by Chipkin Automation Systems, an Approved FieldServer Integrator.
Both Client and Server functionality have been implemented. This means that you can use the driver as a client to monitor/command the devices or you can use it a server to make another type of device appear as if it were a MicroSTAR device. Ie. The server functionality allows you to make a foreign device emulate a MicroSTAR so it can be installed in a MicroSTAR trunk.
|Active Client||16||A maximum of 16 devices may be connected per trunk. This is a limitation of the protocol which only allows 16 possible addresses.|
