Status Synchronized Action Disabled ($Ac_Syna_State) - Siemens SINUMERIK 840D sl Function Manual

Sequence
● Main program
– Call cycle "ZYKLUS_1"
● Cycle "ZYKLUS_1"
– Set the enable for input signal x ($AC_IN_KEY_G_ENABLE)
– Set up the synchronized action with technology cycle "SIGNAL_IN_x"
– Initialize the trigger for action x "intermediate dressing" (R01)
– Grind the component
● Technology cycle "SIGNAL_IN_x" (in parallel with the cycle)
– Identify the input signal ($AC_IN_KEY_G) with the enable active
– Request the enable of action x from the PLC ($AC_IN_KEY_G_RUN_OUT)
– Wait for the enable of action x from the PLC ($AC_IN_KEY_G_RUN_IN)
– Request action x in cycle (R01)
– Feedback signal of the request to the PLC ($AC_IN_KEY_G_RUN_OUT)
– Wait for acknowledgment from the PLC ($AC_IN_KEY_G_RUN_IN)
● Cycle "ZYKLUS_1" (after completing grinding)
– Reset the enable for input signal x ($AC_IN_KEY_G_ENABLE)
– If action x is requested ⇒ execute intermediate dressing
– ... (possibly re-execute grinding/intermediate dressing operations etc.)
● PLC user program
– Function "Enable input signal x":
– Function "Enable input signal x":
– Function "Enable action x":

Status Synchronized action disabled ($AC_SYNA_STATE)

System variable $AC_SYNA_STATE outputs in bit code whether a synchronized action is
disabled via the PLC (see "Coordination via PLC (Page 123)") or via a synchronized action is
disabled (see "Coordination via part program and synchronized action (LOCK, UNLOCK,
CANCEL) (Page 122)").

($AC_IN_KEY_G_ISENABLE)
Set interface signal DBX386.0 ... 7
Logically combine (AND) the input signal from the PLC I/O and the enable of input signal
(DBX390.0 ... 7) - and set the result in the interface (DBX385.0 ... 7)
Check/set the interface signals DBX391.0 ... 7 / DBX387.0 ... 7
