InCyEv In Cycle Evaluation: Time period elapsing while tightening is active, including completed
evaluation
This signal is available as of version V2.300 of the Rexroth Tightening System 350.
Output signal used for:
• Tightening channel (InCyEv)
• Communication unit in single-channel operation (CH x.y InCyEv)
The InCyEv signal shows the period elapsing from the time when tightening is started until evaluation is
completed.
It is set to "high" along with InCy. Once OK or NOK changes to "high", InCyEv is set to "low". While there
is no evaluation ("Play at start switch"), InCyCm is set to "low" no later than when CyCmp changes to
"high".
InfoTool Information tool: Limit value for prewarning reached
This signal is available from version V2.600 of the Rexroth Tightening System 350.
Output signal used for:
• Tightening channel (InfoTool)
This signal turns to "high" when a limit value for the maintenance prewarning set in the channel
configuration has been reached. The signal is set to "low" if monitoring is deactivated or if the set limit
value is reset.
Job Ack 0-7 Job acknowledge 0-7: Acknowledges the selected job
This signal is available in the compact system as of version V2.300, KE as of V2.400 and SE as of
V2.500 of the Rexroth Tightening System 350.
Output signal used for:
• Tightening channel: Compact system (Job Ack0-7)
• Communication unit in single-channel operation (CH x.y Job Ack0-7)
• Communication unit in application operation (KE Job Ack0-7)
The signal acknowledges the selected job.
Using this signal, the PLC can determine whether the job was selected successfully. The job number is
only valid if the acknowledgement corresponds to the selection. The controller always uses the
acknowledged job number as a basis for a tightening operation or application.

This signal is available in the compact system as of version V2.300, KE as of V2.400 and SE as of
V2.500 of the Rexroth Tightening System 350.
Output signal used for:
• Tightening channel: Compact system (Job CyCmp)
• Communication unit in single-channel operation (CH x.y Job CyCmp)
• Communication unit in application operation (KE Job CyCmp)
Job CyCmp = “high” signals the end of the job sequence and the job results processing. The controller(s)
is (are) ready for the next job.
