Chemstation HPLC communication problems

[Norman68]

I'm having problems with my chemstation finding my HPLC's all connected as usual.
It worked fine yesterday but now saying can't find pump, detector, coulmn, etc
I have rebooted PC
Turned off all HPLC units then back on several times but still not finding them

Any ideas please??

Hello,

Your instrument is connected to the PC with GPIB cable or with LAN cable?

What is the revision of the chemstation?

This two informations are very important if you want some help.

I've done stupid stuff to correct stuff like this, like taking all modules out of the configuration, turning EVERYTHING off, starting up again, then letting the software "find" modules and light the icons up green, then move them to the right hand column.
