swlk4w Wiki¶Swagelok 4W actuated valve :
- Actuator : Gulex K8
- Port size : 3/8"
- Port configuration 4 to 1 selector
Same procedure for Linux and Windows.
$ git clone https://forge.clermont-universite.fr/git/swlk4w
Download Windows binaries under the "Fichiers" tab.
For Windows versions earlier than 10, the STMicroelectronics VCP (virtual COM port) driver is required. With Windows versions starting at 10, ST recommends to use the driver provided with by the OS.
Using the software¶
Generate a config file¶
To generate a config file, open a command prompt, and type :
swlk4w -g myconf.conf
Here is the file generated on Windows :
[serial] port_name = COM22 baud_rate = 115200 data_bits = 8 parity = none stop_bits = 1 [data] data_directory = %TEMP% geographical_location = XXX [timing] sync_start_minute_multiple = 15 sec_per_position = 900 sec_read_delay = 10 [sequence] step01 = 1 step02 = 2 step03 = 3 step04 = 4 [captions] pos1 = unused1 pos2 = unused2 pos3 = unused3 pos4 = unused4
Adjust the config file¶
Search the serial port name that your system has given to the valve, and edit
port_name accordingly. Don't change the other parameters.
Set the data directory. This is where the log file with time and valve position will be saved.
Change the station code e.g. to one of the GAW IDs.
- sync_start_minute_multiple : the valve will synchronize with this multiple (minutes). 15 means the valve will start to move at the next 1/4 h.
- sec_per_position : number of seconds to wait in every position.
- sec_read_delay : number of seconds before polling the valve to read back its actual position. Set to 15 s.
This section is used to build a sequence, that will be repeated forever. The sequence is specified in key-value pairs.
Important : the sequence is not played in the order in which the lines appear, but in the alphabetical order of the keys.
Suppose you want to sample ports 1, 2, 1, 2 and 3. You must specify the sequence as follows. Note that the keys are alphabetically sorted.
[sequence] step01 = 1 step02 = 2 step03 = 1 step04 = 2 step05 = 3
