When your see: It Means:
AMP Adjustable Machine Parameters
CNC Computer Numerical Control
CPU Central Processing Unit (the computing part of the (9/260 and 9/290 control)
CPU Board the board that holds the processor of the control. It slides into the enclosure to connect to
the motherboard (9/260 and 9/290 control)
CRT Cathode Ray Tube (the control’s monitor screen)
The Control general term that we use to refer to the 9/230, 9/260, 9/290 or 9/440 control.
E-STOP Emergency Stop
Flash Memory Non-volatile, programmable memory that resides in Flash SIMMs on the CPU board. This
memory backs up the executive program, PAL, and AMP. It retains information even during
power failure
HPG Hand Pulse Generator
I/O Input/Output
I/O CPU One of two CPUs in the 9/290. It processes the machine logic interface and I/O control
information.
Main CPU One of two CPUs in the 9/290 and the only CPU in the 9/230 and 9/260. It processes
internal CNC functions, including system scans and block decode.
MDI Manual Data Input
MTB Machine Tool Builder’s control panel
Motherboard the board that is installed onto the back panel of the enclosure on the 9/260 and 9/290.
Most system connections are on this board.
ODS Offline Development System
PAL Programmable Application Logic
Processor Board the board that is installed onto the back panel of the enclosure on the 9/230. Most system
connections are made on this board.
RAM Random Access Memory
RIO Allen Bradley Remote I/O communications.
SIMM Single, In-line Memory Module. Flash SIMMs are on the lower half of the CPU module. If
you have a 9/290, it has Shadow RAM SIMMs installed on the top half of the module as well
as Flash SIMMs.
Softkeys The row of keys directly below the Operator Panel screen
System Installer The company or contractor responsible for installing this control on the machine
Workstation The IBM or compatible personal computer that the ODS software is installed on
