Manual Description
Models
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.
Part No. Description
25C994 Thermo-O-Flow CGM Installation Kit
Kit 25C994 is used with the following CGM models,
each of which includes all of the remaining parts necessary to install the CGM. See Communications Gateway
Module Instructions - Parts, manual 312864, for repair
parts for these assemblies.
Part No. Fieldbus

CGMDN0 DeviceNet
CGMPB0 PROFIBUS
CGMPN0 PROFINET
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 internal data from the Therm-O-Flow system that can be
viewed or modified by the fieldbus device.

Installation
NOTE: Turn off the main power switch on the
Therm-O-Flow before starting. See the Therm-O-Flow
manuals referenced in Related Manuals on page 2 for
information about turning off the power.
To install the CGM, you will need to drill mounting holes
on the Therm-O-Flow below the electrical control panel
in a location where the CAN cables can be connected to
the CGM. See Figure 1 for the recommended location.
Mounting the CGM
1. Drill the mounting holes.
2. Remove the access cover from the CGM (D).
Loosen the two screws (C) and remove the CGM
(A) from the base (B).
FIG. 1: Mounting Location
The center of the CGM should be 4 inches from the bottom of the electrical control panel and 8 inches from
each side. Refer to the following mounting dimensions
when drilling the holes for the CGM.
NOTE: Mount the CGM with the CAN cable connectors
on the left side to make it easier to connect the cables.
FIG. 2: Removing the CGM Access Cover
3. With the CAN connectors on the left side, mount the
base (B) in the mounting holes using the four
screws supplied in this kit. See Parts on page 12.
4. Mount the CGM (A) on the base (B) with the two
screws (C) that were removed in step 2.
5. Reattach the access cover (D).
Connecting the CAN Cables
1. Disconnect the ADM’s CAN cable from the ADM
and from the splitter on the back of the
Therm-O-Flow’s electrical control panel.
2. Connect one end of the 1.5 m (4.9 ft) CAN cable
included in this kit to the ADM. Run the cable down
and through the opening underneath the electrical
control box as shown in Figure 3.

8. Perform the Install or Update Data Map procedure
in Communications Gateway Module Instructions -
Parts, manual 312864.
9. See the Available Internal Data on page 9 for
details on the fieldbus pinout setup.
10. Perform Setup on page 5 to configure the fieldbus.
FIG. 4: CGM Connectors
5. Attach the two ferrite suppressors included in the kit

* Data instances (setback mode setpoint temperatures) are NOT provided for the PROFIBUS and PROFINET versions of the map since the
field protocols do not support that large of a map size. For PROFIBUS or PROFINET, you should use the data exchange interface to obtain
setback setpoint information.
** For the PROFIBUS or PROFINET versions of the map, 14 should be subtracted from the instance number and 28 should be subtracted for the
input byte count so that the PROFIBUS and PROFINET versions have 56 input instances containing 116 input bytes total.
Zone states are packed in groups of three bits, where each zone state equates to the following. Each zone is packed from bit 0, bit 3, bit 6, bit
9, and bit 12 corresponding to the order presented in the description. 000 - zone is not installed, 001 - zone is off, 010 - zone is in warm up
state, 011 - zone is in heat soak state, 100 - zone at temperature, 101 - zone in setback mode.
Temperature units match units of the ADM. Values are in tenths of a degree (for example, a value of 4005 corresponds to 400.5 °F). Setpoint
temperatures are either for the primary or secondary unit, depending on the system selected by the PLC in the System Control Word.
† See Appendix C - Error/Event Tables on page 22.
See the Status Indication Bit Tables on page 13.
See Appendix B - Data Exchange Interface on page 17.
‡ System Mode/State: 0 = System Off, 1 = Inactive, 2 = Warm Up, 3 = Heat Soak, 4 = Ready (at temperature, heat soak done, pump off), 5 =
Active (at ready and pump ON), 6 = Setback Mode.
