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 9for a list of inter-
nal data from the Therm-O-Flow system that can be
viewed or modified by the fieldbus device.

* 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.

6 After changing the state of the command XX setpoint indications on the map for the Secondary B system bit, the controlling PLC logic should
monitor the corresponding status indication bit and verify it corresponds to the command bit before monitoring the corresponding setpoint indi-
cation from the Therm-O-Flow.
7 The PLC or controlling logic needs to generate a dynamic signal at approximately a 0.333 Hz (1.5 seconds high, 1.5 seconds low) oscillation
rate. The signal is present to enable detection of a communication failure between the Therm-O-Flow system and the controlling logic. The
TOF system also generates the same rate dynamic signal indication (heart beat indication for PLC from TOF) signal for controlling logic to the
monitor.
8 The PLC Control Command bit needs to be set, and the controlling logic needs to generate a valid heart beat output (described in note 7) to
the Therm-O-Flo system before the TOF will grant the PLC requests or commands. If the heart beat output to TOF becomes a static signal
(always low or high) after an extended period of time while the TOF is in PLC control, the TOF reverts to a safe state, and generates a corre-
sponding alarm. This situation would be similar to an operator pressing the key

Temperature Setpoint Zone Designation Table
The following table shows the setpoint designations in
output instance 2 used to command the Therm-O-Flow
temperature zones to the corresponding setpoint. Prior
to writing to instance 2, the PLC needs to write the
desired temperature setpoint (in tenths of a degree for
the selected temperature unit of measure) to output
instance 3 for the selected zone. After the zone desig-
nation has been written, the PLC can monitor the set-
point change by monitoring the correct setpoint
indications: input instances 15-28 or 32-45.

Appendix B - Data Exchange Interface

Appendix B - Data Exchange Interface
The Data Exchange Interface is a bi-directional interface
that enables both transmitting and receiving data
between the Therm-O-Flow system and the controlling
logic (PLC). The interface allows a large amount of data
to exchange between the systems while only occupying
a very small data map to support the exchange. The
interface also allows for future expansion of data without
changing the map structure.
To get or receive data from the supply system, the con-
trolling PLC needs to:
1. Write to the Data Exchange Interface Pointer Output
Designation location on the map (output instance 6)
a value corresponding to the data the PLC wants to
receive.
2. Wait for the Therm-O-Flow to provide the same
Pointer Designation number written in the previous
step at input instance 67 (Data Exchange Interface
Pointer Last Serviced).
3. Read the requested data at input instance 68, Data
Exchange Interface Input Value.
To write or transmit data to the supply system, the con-
trolling PLC needs to:
1. Write the data for the Therm-O-Flow system to the
Data Exchange Interface Output Value location, out-
put instance 7.
2. Write to the Data Exchange Interface Pointer Output
Designation location on the map (output instance 6)
a value corresponding to the data the PLC is going
to transmit to the supply system.
3. The Therm-O-Flow system echoes back to the PLC
the Pointer Designation and the Data Interface
Value after the Therm-O-Flow system processes
the data transmit request to input instances 67 and
68 respectively.
When the controlling logic is exchanging data over this
interface, the Therm-O-Flow system sets the Data
Exchange Interface Active or in Transition status bit
while it processes the request and writes to the Data
Exchange Interface input locations (input instances 67
and 68).
After valid data is present at the input instances, the
Therm-O-Flow system clears the bit. While the bit is set,
the controlling PLC should ignore the interface inputs
until the bit is cleared. After the Therm-O-Flow system
services the request, the designation pointer input
matches the designation pointer output. If the scan rate
of the controlling PLC or control logic is slow enough,
monitoring of the status bit may not be necessary.
NOTE: When changes are made over the Data
Exchange Interface, the Therm-O-Flow system display
screen may not update immediately. It may be neces-
sary to navigate away from the screen, then back to it.
