The following kit includes the Communications Gateway
Module (CGM) parts and software that are required for
Therm-O-Flow 20 or Therm-O-Flow 200 machines using
a CGM. This kit enables the Therm-O-Flow machines to
connect to a fieldbus device.
Kit 25C994 is used with the following CGM models,
each of which includes all of the remaining parts neces-
sary to install the CGM. See
Communications Gateway
Module Instructions - Parts,
manual 312864, for repair
parts for these assemblies.
Overview
The Communications Gateway Module (CGM) provides
a control link between the Therm-O-Flow (TOF) system
and a selected fieldbus. The control link provides the
means for remote monitoring and control by external
automation systems.
The data available to the fieldbus from the CGM
depends on the amount of channels installed on the
Therm-O-Flow system. A data map is available on a
token provided in this kit.
See
Available Internal Data
on page
9
for a list of inter-
nal data from the Therm-O-Flow system that can be
viewed or modified by the fieldbus device.
