Hi,

I'm developing record support files and streamdevice protocol file

for vacuum guage controller Inficon VGC502. This controller can connect to two gauges(channels).

I don't know what are the good streamdevice protocols to process the following response format. Would you please provide suggestions?

1. the command "TID" returns guage identifications:

response example 1: noSENSOR,noSENSOR

response example 2: MAG,MAG

The response above has two parts, corresponding to two gauges. The length of each part is not fixed.

2. the command "RES" returns a list of all present error codes. The list is of variable length.

response example 1: 0

response example 2: 2,3,4

0 –>  No error
1 –>  Watchdog has responded  
2 –>  Task fail error
3 –>  FLASH error
4 –>  RAM error
5 –>  EEPROM error
6 –>  DISPLAY error
7 –>  A/D converter error
8 –>  UART error
9 –>  Gauge 1 general error
10 –>  Gauge 1 ID error
11 –>  Gauge 2 general error
12 –>  Gauge 2 ID error
13 –>  Gauge 3 general error
14 –>  Gauge 3 ID error

3. the command "SPS returns the switching function status. 0 means Off, 1 means On.

response example 1:  0,0,0,0

VGC502 has 4 switching functions, so the response has 4 zeros/ones.

VGC503 has 6 switching functions, however, what protocol could I use to support both VGC502 and VGC503?
