I have schneider canopen (Twido) PLC on filling machine. The
screen give me alarm that the door is open. I checked there is no
door open, so i can not start the machine. So I want to ask, how can I
reset the alarm? And what type of cable i can used to enter to the
program of the plc with Twidosuite?

It is really hard to give you the kind of specific advice you want. I suspect that somewhere in the manual it tells you how to reset alarms. It's likely that there is a switch on the door that's not being made; that's what the alarm represents. You might want to start by looking at the schematics for the door switch and see how that switch actually works and how it hooks you to the plc.
