The type number is applied by the tightening system with rising edge of InPos. The number must be stable
until AckInPos acknowledgement. The type number is used to select a configuration stored in the
tightening system (assignment of tightening results to QIs):
The VarIdent codes are applied by the tightening system with rising edge of InPos. The data must be
stable until AckInPos acknowledgement.
Profinet interface - Tightening system outputs (PLC inputs)
The following block describes general signals of the tightening cell (see table
The following PLUS communication signals are also included:
•
ReportOK: This signal is set by the tightening controller after successful results data transmission to
PLUS.
•
ReportNOK: This signal is set by the tightening controller if an error occurred during results data
transmission to PLUS.
•
AckReportStart: This signal is set by the tightening controller as acknowledgement for the
StartReport signal of the PLC (see above).
•
AckInPos: This signal is set by the tightening controller as acknowledgement for the InPos signal of
the PLC (see above).
•
AckTypOk: This signal is valid with the rising edge of AckInPos and indicates that the ID codes and
type information of the PLC have been successfully accepted and decoded by the tightening
controller.
•
ChnErr: New channel system error is ready for application by the PLC (see below, signals
Ch_ErrCode/Ch_ChnNum/Ch_ErrClass).
