7.1.6.9 VACON Safety Control Word (VS_CW)
The standard S_STW1 and S_STW2 do not include all safety functions that are supported by the Advanced safety option board.
However, a vendor-specific VACON Safety Control Word provides a full access to the safety functions and some extra features over
fieldbus. The bit value 1 means that the signal is "non-active" and the value 0 means "active". All unused bits must be set to 0. Set-
ting their bit value to 1 will cause a fault.
