8.4.3 Data blocks
The functions of the data blocks are described below. For the function of each bit of a data
block, refer to the separate input/out signal documentation.
• DB2: PLC messages (self-diagnosis information)
• DB9: Signals sent in synchronization with the PLC scanning between PLC and NC
• DB10: Signals sent between PLC and NC as shown below. The man-machine communi-
cation (MMC) selector signals and MMC status signals are included.
• DB11: MMC or machine control panel mode signals sent from PLC to NC. NC return
the signals indicating the current mode.

• Control signals: MCS or WCS current position display and key disable
• Machine operation: Input from the machine control panel
• PLC messages
• PLC status signals
• DB21/22: Signals as shown below
• Control/status signals: Signals periodically sent from OB1
• Auxiliary/G functions: M code, G code, and S commands
• Tool management functions
• NCK functions: PLC function calls
• DB31-38: Servo feed/spindle signals as shown below
• Signals between feed and spindle
• Feed signals
• Spindle signals
• Drive signals
• DB71-73: Tool management signals
PLC/NC
