Reglo-CPF Digital

The package is not fully compatible with Windows 10. It is known that the command to set the calibrated flow rate does not work in Windows 10.

Getting started

Check the examples folder for example script on how to use the RegloCPF module.

To connect to the pump in Python, you need to know the comport of the pump when it is connected to the computer. To know this, before plugging the pump into the computer open the Windows Device Manager program and expand Ports. Then plug in the pump and see what new port appears, e.g. COM6. This is what you will use to create the SF10 instance in Python to connect to and control the pump.

Structure of commands:

The address is followed by a character. Some commands have additional parameters that always consist of 4 or 5 figures. The command string is completed by a carriage return (ASCII 13, ). The pump confirms most commands with an asterix *, Yes/No inquiries are answered by + (yes) or - (no). Multi-digit replies are concluded by a carriage return (ASCII 13, ) and a line feed (ASCII 10, ).

Incorrect commands are answered by #. If the pump is in the state of overload, each command is responded with #. Numerical values are confirmed as 3 to 5-digit figures. 4 or 5 digits are numerals, one digit is either a decimal point or a preceding blank space
