The
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
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.
