Ready for switching on (central signal for "ready for switching on" state for DO) as of firmware version
V2.6
The relevant DO in the drive/module line-up of a CU uses this signal to notify the CU that it is
"ready for switching on". The signal is an AND operation which includes all "ready for
switching on" signals of the DOs assigned to a CU (infeeds plus Motor Module/Power
Module).
The DO1 telegram (telegrams 39x) signals the readiness of the DOs in the CU status word
(CU_ZSW1.6) before the start command is issued.
The "ready for switching on" signal is evaluated continuously in cyclic mode.
● Ready for switching on = 1:
● Ready for switching on = 0:
Terminal Modules TM31, TM41, TM15-IO
The Terminal Modules generate their own ready signal when they have finished powering
up.
The signal from a Terminal Module is evaluated on the axis DOs provided that a BICO
relation to the module has been configured. If the Terminal Modules signal "not ready", the
DOs remain in the "switching on inhibited" state. No start commands are expected while the
DOs are signaling "switching on inhibited".

At least one of the active DOs assigned to a CU is in the "not ready for switching on"
state.
All the active DOs assigned to a CU are in the "ready for switching on" state. Deactivated
DOs are interpreted as "ready for switching on".
