General logic outputs
/ALARM (M5507)
The CNC sets this signal low in order to tell the PLC that an alarm or emergency condition has been
detected. This signal will be set high once again, once the message from the CNC has been
eliminated and the cause of the alarm has disappeared.
Likewise, while this signal is low, the CNC keeps the emergency output active (low).

MANUAL (M5508)
The CNC sets this signal high to tell the PLC that the JOG (Manual) operating mode is selected.
AUTOMAT (M5509)
The CNC sets this signal high to tell the PLC that the automatic operating mode is selected.
MDI (M5510)
The CNC sets this signal high to tell the PLC that the MDI mode (manual data input) is selected
in one of the operating modes (JOG, automatic, etc).
SBOUT (M5511)
The CNC sets this signal high to tell the PLC that the single block execution mode is selected.
CUSTOM (M5512)
It indicates to the CNC which work mode is currently selected:
CUSTOM = 0 M or T work mode.
CUSTOM = 1 MC, MCO, TC or TCO work mode.
When having 2 keyboards, this variable may be used in the PLC in the following cases:
• To govern the keyboard switching board.
• To know the source of the keys and inhibit the desired keys.
Sample
/ALARM AND (other conditions) = O1
The emergency output O1 of the PLC must be normally high. If an alarm or an emergency is detected
at the CNC, the emergency output O1 must be set low (0V).
