ACS800 MASTER FOLLOWER STOP OPTION BY PROGRAMMING IN CONTROL PANEL
2 numbers ACS800 drives are in master-follower configuration mode by ddcs and also connected with rpba-01 for communication from dcs.
My question is, in M-F mode how can i stop 2 drives at a time without any harware connection when follower drive will suddenly in trip condition?
is there any possibilities to solve this problem in control panel of drive by programming?

I think it is not possible to do that without hardware connection between master and follower.
You could find the description in Master Follower manual, for example 3AFE64590430
Some statements from there:
1. Connect the external control signals to the Master. Wire the Run enable signal of the Master via the fault indicating relay output of the Followers
2. To avoid conflicting control, drives coupled to the same machinery should receive the external control signals only via the Master. General rules:
- Connect all external control signals to the Master drive only.
- Never control the Follower(s) with the Control Panel or through a fieldbus system
