6.1 General consulting signals.
CNCREADY
This mark indicates the CNC status. It is set to "0" when the CNC is in an error state (red
status window) and to "1" if otherwise.
Include this mark in the PLC maneuver to enable the drives.
READY
There is a mark for each channel. The mnemonics for each channel are the following.
READYC1 READYC2 READYC3 READYC4
This mark indicates the status of the CNC channel. It is set to "0" when the CNC is in an error
state (red status window) and to "1" if otherwise.
SERCOSRDY
In Sercos configuration, this mark indicates the ring status. The CNC sets this mark high (=1)
to indicate that the Sercos ring has been properly initialized.
All the drive status consultations (DRSTAF DRSTAS) and the read/write (CNCRD CNCWR)
operations of the drive variables are conditioned by this mark.
START
There is a mark for each channel. The mnemonics for each channel are the following.
STARTC1 (can also be programmed as START)
STARTC2 STARTC3 STARTC4
The CNC channel activates this mark to indicate to the PLC that the [START] key has been
pressed at the operator panel. If the rest of the conditions are met (hydraulic, safety, etc.),
the PLC must activate the CYSTART mark in order for the program to start running. See
"CYSTART" on page 315.
RESETOUT
There is a mark for each channel. The mnemonics for each channel are the following.
RESETOUTC1 (can also be programmed as RESETOUT)
RESETOUTC2 RESETOUTC3 RESETOUTC4
When pressing the [RESET] key or when the PLC activates the "RESETIN" mark, the CNC
channel assumes the initial conditions and sets the "RESETOUT" mark high (=1). This mark
stays high (=1) for a time period set by (g.m.p.) MINAENDW. See "RESETIN" on page 316.
