In this case, the corresponding output values (- xDone,- xError,- iError) are present at the outputs for exactly one cycle.- ETrigA - xAbort- BOOL- TRUE: Action is stopped immediately and all outputs are reset to their initial values.- ETrigA - Output - xDone- BOOL- TRUE: Action successfully completed- ETrigA - xBusy- BOOL- TRUE: Function block active- ETrigA - xError- BOOL- TRUE: Error occurred, function block aborts action- FALSE: No error- ETrigA - xAborted- BOOL- TRUE: Action aborted by user- ETrigA - Input - usiCom- USINT- 1 - index of master 1: first Ethercat master - wSlaveIndex- WORD- index position to read identifcation from 0,1. - udiTimeOut- UDINT- Timeout for operation in ms - xReadReg0x12- BOOL- Flag if register 0x12 (station alias) should be read - xReadReg0x134- BOOL- Flag if register 0x134 (explicit device identification) should be read - xReadRegAdo- BOOL- Flag if register Ado should be read - wAdo- WORD- The address of the ado identification - Output - wStationAlias- WORD- Result for Register 0x12 - wReg134- WORD- Result for 0x134 - wAdoValue- WORD- Result für ADO identification
