Communication Protocol

[eeycn0128]

I have a pressure controller PX1. Where could I find the communication protocol, e.g. command for writing and reading info?

Hello,

Please find below the manual datasheet where are listed the commands used to control a PX via the RS232 protocol. Note that it is also available on our website, in the product page: https://www.fluigent.com/industrial/industrial-products/standard-industrial-components/fluigent-px/)

Manual datasheet: px_manual_datasheet_v3.pdf

If you want to control the PX via USB, then follow the SDK manual and use it as you would do for an MFCS.

Hope this helps

Hello @eeycn0128 ,

Can we assume that my message answered your questions? If yes I will close this issue.

Thank you.

Hi,

Is there any command for initialization? I didn't find it in the manual.

Hello,

When using the RS-232 interface, there is no initialization command. You can open the serial port and enter any of the commands listed in the manual directly.

When using the USB interface with the SDK from this repository, there is the fgt_init function, but it is called implicitly if needed when any of the other functions is called.

Best,
Ygor

I am controlling the PX-345 through the RS-232 port. I can set and query successfully. I do not see a command to Read the current pressure setpoint. Alpha can be set and checked, pressure SP cannot (that I can see).

The query equivalent of:
CHAN:1P:XXX

I tried the question mark, no success.
