Schneider M580 HotStandby Remote Rack/Module Status

[hmi_plc_01]

Hi Folks,

We have this M580's configured as hotstandby and is curious if it is possible to monitor the modules on the remote racks. Unity pro documentation says %SW160-%SW167 but not so sure if these are only for local racks (M580 standalone configuration).

TIA

Installable CRA racks goes on some CPU models over 8 racks but local racks have limit 4 or 8.
According that I think that %SW160..%SW167 are only for local racks.


You can read module status from DDT variables and as this is reduntant system then IO nad modules are always DDT-variable types.
