address single bit in variable #12

Closed martinschki closed 5 years ago

Is there a way to address a single bit from a variable? e.g. MAIN.variable.0 where MAIN.variable is a variable with type "WORD" in the PLC It works in the PLC, it would be awesome also here...

Maybe in TW3 if you overload an type pointer like: TYPE ST_ControllerData : STRUCT nStatus_OperationEnabled : BIT; nStatus_SwitchOnActive : BIT; nStatus_EnableOperation : BIT; nStatus_Error : BIT; nStatus_VoltageEnabled : BIT; nStatus_QuickStop : BIT; nStatus_SwitchOnLocked : BIT; nStatus_Warning : BIT; END_STRUCT END_TYPE

There nothing in the ADS documentation about this. Would be glad if you could ask Beckhoff support the question. support@beckhoff.com
