1. ATMI TGM Serial Driver Description

The ATMI-TGM driver allows the FieldServer to transfer data to and from devices over RS-232
using the ATMI-TGM printer port protocol.

This driver connects to an ATMI TGM device using a serial connection. One device may be
connected per FieldServer port. (This limitation exists because the protocol is node-less; that is,
messages do not contain information about the node and thus messages from different TGM
devices could not be distinguished if they were connected on the same port.)

The driver reports Gas and sensor readings and Gas alarm / warning status. The driver reports
TGM module malfunctions.

The driver is a client only driver.

When reporting port and sensor data, the driver reports the gas name by setting a gas name
index value. The index value is obtained from a list of gas names / index values hard coded into
the driver. The list may be extended and/or modified using the configuration by using
appropriate entries in the configuration CSV file. The driver reports a second gas name index
value based on reading the TGM calibration report. When the report is read each gas is
allocated an identifier value based on the gas’s position in the configuration report.

The driver does not provide emulation of a TGM device and thus may not be used as a server.

It is not possible to use this driver to write to the TGM device.

3.1. Hardware Connection Tips / Hints

The following notes are provided from a TGM manual:

The TGM code constantly checks the status of the DSR input of its serial ports connected to
the DTR output of the remote serial ports. If the TGM DSR is NOT ASSERTED (FALSE),
then the TGM software will suspend serial data output out of TGM Tx, and start a timeout
timer (the default timeout time = 30 seconds as set in CONFIG.DAT). During this timeout, if
the DSR is ASSERTED (TRUE), then the TGM software will begin transmitting data. If the
DSR hold exceeds the (configurable) 30 second timeout, the TGM will report a malfunction:
MALFUN PRINTER OFF LINE hh:mm dd mmm yy
MALFUN REMOTE OFF LINE hh:mm dd mmm yy
depending upon which port has timed out. Restoration of the DSR status as ASSERTED or
TRUE will clear the above malfunction(s). The above malfunctions will occur if the active
TGM serial ports (printer or remote) are not connected upon bootup with the proper null
modem cables to active serial ports with DTR (connected to theTGM DSR)
ASSERTED/TRUE. The TGM can have the hardware control defeated by jumpering CTS to
DTR to DSR on the TGM side of the connector.

The driver does not provide the hardware handshaking required and assumes the hardware
control has been defeated with jumpers.

4. Configuring the FieldServer as a ATMI TGM Serial Client

For a detailed discussion on FieldServer configuration, please refer to the FieldServer
Configuration Manual. The information that follows describes how to expand upon the factory
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files
provided with the FieldServer).

This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a TGM device.

4.1. Data Arrays/Descriptors

The configuration file tells the FieldServer about its interfaces, and the routing of data
required. In order to enable the FieldServer for ATMI TGM Serial communications, the driver
independent FieldServer buffers need to be declared in the “Data Arrays” section, the
destination device addresses need to be declared in the “Client Side Nodes” section, and
the data required from the servers needs to be mapped in the “Client Side Map Descriptors”
section. Details on how to do this can be found below.

Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

4.4.4. Map Descriptor Example #1 – CALR Report.

To be useful to the upstream device the driver reports gas concentration values and gas names from the QLA report. In reporting the
gas names it is most useful when a driver stores an index value which is used to imply the gas names. The reason this is most useful
is that it is typically easier for automation devices to work with numbers and not text.

When the driver reads the Calibration report, it does two things.

1) It stores a string of gas names vs. index values in the Data Array. This string can be viewed using the Ruinet Utility and may be of
help in interpreting the gas name index values stored by the QLA report.

2) The data is stored internally by the driver and when a QLA report is parsed the driver looks the gas names up in the CALR report
data and uses the lookup to determine what gas name index value to store.

// Client Side Map Descriptors

RD_CALR, DA_CALR, 0, RDBC, Node_A, 0, 100, 600s, CALR

Although not
mandatory it is
recommended
that each MD is
given a unique
name.

A list of gas names vs. index values is
stored in the Data Array specified here.

In this particular example, the list is
stored as an ASCII string and hence it
makes most sense to ensure that the
Data Array’s format is BYTE so that it
can be viewed as a string when using
Ruinet.

Data storage
starts at this
location in the
Data Array.

Tells the driver to repeat this
read task continuously. The
polling interval is set by the
Scan_Interval parameter.

For the CALR report is may
also make sense to use the
‘ARS’ function which gets the
driver to read this data once
each time the driver restarts.

The node name connects the Map Descriptor to a
Node definition which in turn is connected to a port.
That is how the driver knows which port to use to
poll for this data.

Reserve enough
space in the Data
Array to store the
gas/index string.

4.4.5. Map Descriptor Example #2 – QLA Report.

In this example, a Map Descriptor is created to read the Latest Area Report (QLA). This report contains gas concentration and status
for each port and sensor. Ten Data array elements are required for each port / sensor that is reported. The poistion in the array is
dependent on the port/sensor number. Appendix B provides additional information. By specifying the extra arrays (DA_Bit_Name and
DA_Byte_Name) the driver stores additional information.

4.5. Map Descriptor Example #3 – QIR Report – Malfunctions

In this example the Map Descriptor is configured to read the incident report. The driver parses the report looking for malfunctions and
reports that show a malfunction has been cleared. Other incidents / events are ignored except for events #19 and #37 which cause
all malfunctions to be cleared. The Driver updates the array setting values to 1 (malfunction) or zero when a malfunction has been
cleared. The position indicates the malfunction number. The driver has a list of malfunctions and index numbers stored internally.
Refer to Appendix A.2 for this list. The list can be modified in the configuration CSV file.

CAUTION: When the QIR report is polled it responds with the latest incidents only. This means that care should be taken to
synchronize the FieldServer and the TGM. Read more about this in Appendix B.8

Appendix A. TGM Tables

Appendix A.1. Hard Coded Gas Name Table

This table is used by the driver when storing data from the QLA report. The driver looks the
reported gas name up in this table. If a match is found then the driver stores the
corresponding index value in the Data Array. If no match is found the the driver stores a
value of –1.

The table may be extended/modified using the configuration file. Refer to Appendix B.4

Appendix A.2. Malfunction Table

When an event is reported in the Incident Report (QIR) then the driver compares the event
description to text in the table below. If the text matches an an entry in the ‘Malfunction’
column (and is preceeded by the string MALFUNC) then the Data Array element at the
specified offset is set to 1. If the text matches the ‘Return to Normal’ text then the
malfunction is considered as cleared and the Data Array element is set to zero.

The Data Array elements are all set to zero when

Event 19 reports ” ALARM RESET “ or Event 37 reports “ALL MALFUNCTIONS CLEAR”

The Malunction text strings generated by the TGM unit are not the same for all units. They
can be customized in theTGM’s config.dat file. For this reason, this driver allows the strings
in the table below to be customized too – see Appendix B.5. In addition to allowing this
table to be customised in the configuration file, the driver can use a config.dat file to directly
customise the table – see Appendix B.7

Appendix A.3. Gas Concentration Engineering Units

This table is used by the driver when storing data from the QLA report. The driver looks the

stores the index value. If a matching entry cannot be found then the driver stores a value of
–1. (Note that when –1 is stored in a BYTE or UINT16 formatted Data Aray it will appear as
a positive number such as 255 (Byte Array) or 65535 (uint16 Array).

Appendix B. Advanced Topics

Appendix B.1. How Malfunctions are determined and stored

• The notes below describe how the driver parses incident reports obtained by the QIR
poll.

• The driver starts at the end of the report and works its way to the top, line by line.

• Each line is inspected to see if it contains either of the following strings

“ALARM RESET"
"ALL MALFUNCTIONS CLEAR”

• If either is reported then the driver sets all the array elements to zero except those
corresponding to lines of the report appearing after (and hence later in time) one of the
above lines that indicates that malfunctions be set, in which case those particular
malfunctions will be reported as 1’s in the Data Array.

• When either one of these two events is found the driver stops parsing the report as all
prior lines predate the clear event.

• Each line is inspected for the string “MALFUN”. If it is found then ‘Event’ field in the
report is inspected and the description is extracted and compared to the malfunction list
provided in Appendix A.2. If a match is found the driver uses the offset value and sets
the corresponding element in the Data Array to 1.

• If the string “MAFUN” is not found then the description found in the ‘Event’ field of the
report is used to look up a ‘Return to Normal’ event in the table provided in Appendix
A.2. If a match is found then the corresponding offset in the Data Array is set to zero.

• If the description is not recognized then it it is ignored.

Example

Only the Malfunction ‘COUS SENSOR TIMEOUT’ would have its Data Array element set to

1. All others will be set to zero. The reason is that all events above the ‘ALARM RESET’ line

are considered to be prior to the reset and are thus cleared when the driver sets all the Data
Array elements to zero. The timeout event occurs later and hence its malfunction is set.

When the driver uses the lookup table to see if it recognizes the event description then it
compares the strings looking for an exact match. If no exact match is made then the driver
uses a so-called ‘soundex’ function to see if the strings are very similar, if they are then they
are considered to be matched. If a similar match is made the driver reports this in the error
log.

Appendix B.2. How Gas Data is Stored

• The QLA reports provides Gas Concentration values for each configured port/sensor
connected to the TGM.

• The driver stores the data using the “Data_Array_Name” and “Data_Array_Offset”
parameters specified on the Map Descriptor. Two additional Data Array’s can be
specified to tell the driver where to store the gas names and egineering units.

• The position at which data is stored in the array is deprendent on the TGM port/sensor
number. Use the following formula to determine the position.

Appendix B.3. Adding/Modifying Gas Concentration Value Engineering Units

The configuration CSV file can be used to modify the table of engineering units that is hard
coded into the driver. This table is presented in Appendix A.3

Add a section to the configuration file which is similar to the following example.

In the example below the Units specified is ‘PPM’, an entry from the existing list. When the
driver finds the lines below, it will update the index value to 20.

// Change index value of existing unit to 20.

Driver_Table
TGM_Units_Name, TGM_Units_Index_Value, Protocol
PPM, 20, TGM

In the example below the units specified are ‘gpl’ and they have been assigned an index
value of 7.

// Add a new engineering unit

Driver_Table
TGM_Units_Name, TGM_Units_Index_Value, Protocol
gpl 7, TGM

Appendix B.4. Adding / Modifying Hard Coded Gas Names

When a gas concentration is reported, the driver reports the gas name by looking up the gas
name in a list of hard coded gas names. When a match is found the driver stores the
associated index value. The table may be modified/extended in the configuration CSV file.
The table of names and index values is provided in Appendix A.1

Add a section to the configuration file which is similar to the text found in the examples
below.

In the example below the gas name specified is ‘H2’, an entry from the existing list. When
the driver finds the lines below, it will update the index value to 20.

// Change index value of existing gas to 20.

Driver_Table
TGM_Gas_Name, TGM_Gas_Index_Value, Protocol
H2, 20, TGM

Appendix B.5. Adding / Modifying Malfunction Strings

When an event is reported, the driver compares the “MAFLUN” events to those in the table
provided in Appendix A.2. The table can be modified or extended.

Add a section to the configuration file which is similar to the text found in the examples
below.

In the example below the gas name specified is ‘DISK NEARLY FULL’, an entry from the
existing list. When the driver finds the lines below, it will update the index value to 20.
Ensure the index value is less than 100.

// Change index value of existing malfunction.

Appendix B.6. Adding / Modifying ‘Return to Normal’ Strings

When an event is reported, the driver compares the description to those in “Return to
Normal” column of the table provided in Appendix A.2. The table can be modified or
extended.

Add a section to the configuration file which is similar to the text found in the examples
below.

The index value allocated should match the malfunction index for the driver to clear the
malfunction when the return to normal event is found.

In the example below the gas name specified is ‘DISK NO LONGER FULL, an entry from
the existing list. When the driver finds the lines below, it will update the index value to 20.
Ensure the index value is less than 100.

// Change index value of existing Return to Normal Event.

Driver_Table
TGM_Event_Normal_Name, TGM_Event_Normal_Index, Protocol
DISK NO LONGER FULL, 20, TGM

In the example below the gas name specified is ‘DISK NOT FULL’ and it has been assigned
an index value of 20. It will be added to the table.

// Add a new Return to Normal Event

Driver_Table
TGM_Event_Normal_Name, TGM_Event_Normal_Index, Protocol
DISK NOT FULL, 20, TGM

Appendix B.7. Using the TGM’s Config.dat file to customize malfunctions

Copy the TGM’s config.dat file to the FieldServer as a file called atmitgm.ini. When the driver
starts it looks for this file and updates the malfunction table based on the malfunction strings
found inside the config file. The Ruinet utility is required

Ruinet –i1.2.3.4 –u0 –lc:\…\config.dat –fatmitgm.ini

Where

1.2.3.4 is the IP address of the FieldServer

c:\….\config.dat is the path of the file to be downloaded from your C driver.

To stop the driver using the ini file remove it from the FieldServer by deleting it.

Ruinet –i1.2.3.4 –zatmitgm.ini

When the driver inspects the configuration file it searches for the string “malfunStat” and
uses the table that follows to update the malfunction table. Note that the config file only
contains malfunction strings and does not provide the ‘Return to Normal’ strings. Thus, if
the config file contains a malfunction for which the driver does not have a matching return to

normal string then you will need to add the matching ‘Return to Normal’ string. This process
is described in Appendix B.6

Appendix B.8. Synchronizing Malfunctions

THE Incident Report (QIR) only reports events which occurred since the previous poll.

The following procedure is recommended for synchronizing the FieldServer and the TGM

1. Turn off the FieldServer. Clear all events on the TGM and then restart the FieldServer.

Or

2. With the FieldServer online, cause the TGM to send an RESET ALARMS message to
the FieldServer.
