Marks / Registers. Meaning,
SETTMEM The PLC sets this mark high (=1) to activate the tool manager
emergency.
RESTMEM The PLC sets this mark high (=1) to cancel the tool manager
emergency.
TMINEM The CNC sets this mark high (=1) to inform the PLC that an
emergency has occurred at the tool manager. To generate an
emergency at the manager from the PLC:
(1) Activate the emergency.
DFU (error condition) = SET SETTMEM
(2) Make sure that the emergency has occurred before canceling it.
TMINEM AND DFU (removal condition) = SET RESTMEM
The manager sets the SETMEM and RESTMEM signals low
(=0).
