Purpose:<\/span><\/strong><\/p>\n<\/div>\n

\n
\n

Manage communication with Alicat Scientific Mass and Volumetric Precision Gas Flow Controller to read and monitor gas flow data, including pressure, temperature, and flow rates.<\/p>\n<\/dd>\n<\/dl>\n

\n
\n\n\n\n<\/colgroup>\n\n\n
N\/A<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/dd>\n<\/dl>\n

No command-line arguments are required. The program operates independently and can be run in the background using ‘&’.<\/p>\n

Configure this program to run continuously in the CyFlex environment. Ensure the configuration file is present and properly set up for operation.<\/p>\n

The ASC configuration file “\/specs\/alicat_mf.cfg” file must exist.<\/p>\n

A copy of the alicat_mf.cfg file is located in cyflex\/specs.def at CTC and in cyflex\/specs.def at “cmxnode1”<\/p>\n

The following variables will be created if they do not exist:<\/p>\n

REAL<\/p>\n\n\n\n\n\n\n\n\n
alicat_press<\/td>\nPress measure by device in PSI_A<\/td>\n<\/tr>\n
alicat_temp<\/td>\nTemperature measured by the Device in C<\/td>\n<\/tr>\n
alicat_co2_vf<\/td>\nCO2 volumetric flow<\/td>\n<\/tr>\n
alicat_co2_mf<\/td>\nCO2 massflow<\/td>\n<\/tr>\n
alicat_mf_rate<\/td>\nCurrent massflow rate<\/td>\n<\/tr>\n
alicat_setrate_mf<\/td>\nValue to set the massflow rate when the alicat_sp_cmd is received<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The following event will be created by the application and will be set if there is a comm loss:\u00a0
\nalicat_comm_loss<\/p>\n

The following event will be created by the application and is used to signal the application to set setpoint flow rate:
\nalicat_setpoint<\/p>\n<\/dd>\n<\/dl>\n
