TPGx00 is shorthand for the TPG300 and the TPG500 Pfeiffer Vaccuum Gauges which use the same TPG300 IOC, which controls a series of four pressure sensors (A1, A2, A3, A4).
To configure the IOC for the 500, define the MODEL macro: it defaults to TPG300
These devices are similar to the TPG26x and TPG36x, but have 4 pressure sensors to read from, and a slightly more complicated IOC. All their manuals can be found in <share>\ISIS_Experiment_Controls\Manuals\Pfeiffer TPG<xxx>.
The TPG500 is the slightly newer version of the TPG300; the main differences between these two devices is in their communication protocols. See the manuals for what these properties are used for.

The IOC currently supports the use following commands with the TPGx00 devices:
| Command | Description |
|---|---|
Pxx, where xx is A1|A2|A3|A4
|
Gets the pressure measurement from the specified channel |
ERR |
Get the error status of the device |
SPS |
Get the statuses of all the switching functions |
SPx, where x is 1|2|3|4 (+ A|B for 300) |
Get/set the threshold settings for a specified switching function |
UNI |
Get the unit of measurement |
UNIx, where x is 1|2|3 (+ 0|4|5|6 for 500) |
Set the current unit of measurement |
