FieldServer Driver

FS-8700-125

Stulz

Description

The Stulz driver allows the transfer of data from a Stulz device using the Stulz monitoring protocol version 1.7. The Fieldserver can act as a Client.

Currently, only the C6000 microcontroller is supported as the protocol only specifies read capabilities on that unit.

The Client is configurable to read all information into separate data points and supports writing to selected points as specified below.

It supports the following formats:

Float values
Binary values
Integer values

Fieldserver Mode	Remote Nodes	Comments
Client	32	The protocol supports only one Client per bus, which can poll 32 server devices
