Outputs used for controlling the station:
Variable
Type
Use
MODE
INT
Set to number of mode to use in next cycle. Sampled on the positive
edge of START.
RESET
BOOL
Reset servo errors on a positive edge. Should only be set True if the
station is idle.
Note! All servos connected to the station are reset.
START
BOOL
Starts cycle. A positive edge will start the first step in the cycle. This
signal is ignored if the station is not idle, or if STEPSTOP,
EMERGSTOP or MACHINESTOP is True.
LOOSENING
BOOL
Loosen cycle. When set to True mode 50 will be started and all
cycle data and trace data will be automaticly dropped. See detailed
description below.
Note that the cycle and trace data that is produced while loosening
is active is dropped and will not be stored in the system.
STEPSTOP
BOOL
Step stop. Set to True to stop current step with status OK. Next
START will continue with next step in the cycle.
EMERGSTOP
BOOL
Emergency stop. Set to True to stop the cycle with status NOK.
Next START will start cycle from beginning.
MACHINESTOP
BOOL
Machine stop. Set to True to stop the cycle with status NOK. Next
positive edge on START will start a new cycle.
MONSTART
BOOL
Start monitoring. Set to True to start monitoring of the spindles. This
signal is ignored if the station is not idle.
MONEND
BOOL
End monitoring. Set to True to end monitoring of the spindles.
DATAHOLD
BOOL
Data hold. Set to True, before starting a cycle, to hold the
transmission of cycle data. The data is released when the input is
set to False if the station is idle (status < 4) and DATADROP is
False.
Note that the cycle data that is produced while hold is active will
contain only one station header, the one produced by the first start.
DATADROP
BOOL
Data drop. If True when a cycle data is to be reported then the data
is dropped, without any distribution.
Cycle data is normally reported when the cycle ends but if
HOLDDATA is active it is reported when DATAHOLD is set to False.
TRACEDROP
BOOL
Trace drop. If True when the cycle end the traces will not be
distributed to any device.
GENEVENT
INT
Set to a code 1-10 to generate an event. The code used will be
displayed together with the event.
STEPTYPE
INT
Control data used for the PLC - Run PLC step used in the tightening
program. Defines which control function the step should execute.
See the step description for valid values.
STEPVAL
REAL
Control data for the PLC - Run PLC step. Used as target value.
