1. Overview
On the control boards of CNC, Flash ROM modules (hereafter, “FROM”) and Static RAM
modules (hereafter, “SRAM”) are mounted. In these FROM/SRAM modules, the important
data that decides the CNC/PMC characteristic is stored. Typical data that stored in each
module is as follows.
A. FROM included files
<System files>
CNC control software
PMC management software
Servo management software
Ethernet management firmware
<User files>
Ladder program
C-language executor
Macro executor
Order made macro
PMC C-language program
B. SRAM included data
NC programs
CNC/PMC parameters
Tool offset
Custom macro variables
Up to now, these data are managed at CNC BOOT function with using memory cards at every
CNC control unit.
When Open CNC is introduced, the PC function is connected to CNC control unit through High
Speed Serial Bus (HSSB) or Ethernet. Then the input/output of these FROM/SRAM data can
be done at the remote place apart from the shop floor of CNC control units. And using PC
function, the centralized management of FROM/SRAM data of multiple CNC control units can
be achieved.
In this document, we would like to explain the specification of “FROM/SRAM Management
Utility” that runs on the PC function.
