Coordinator Module Section 4-1

System Setup

Flash Memory

The System Setup contains software switches used to make initial settings and other settings. As shown in Appendix C System Setup, Auxiliary Area Allocations, and Built-in I/O Allocations, addresses (words and bits) are allo- cated for settings in the System Setup. The addresses can normally be ignored when making the settings, however, because the settings follow CX- Programmer menus.

When the user writes to the Coordinator Module, the user program, System Setup settings, other parameters, and part of the DM Area are automatically backed up to flash memory.

4-1-2 Coordinator Module Operation

The following flowchart shows the operation of the Coordinator Module. Pro- gramming is executed before I/O is refreshed and peripherals are serviced. This cycle is executed repeatedly.

Power ON

Startup	• Initialize hardware memory	• Clear I/O memory.
initialization	and system work area.	• Check user memory.
	• Detect connected Motion	• Clear forced status, etc.
	Control Modules.

Cycle time

Common	• Read DIP switch settings.	• Check I/O bus.
processing		• Check user program memory.
Program	• Operation processing: Execute the user programming.
execution	• Error processing: Turn OFF outputs.
	• After error: Clear I/O memory (unless a FALS instruction caused
	the error.)
I/O	Refresh built-in I/O.
refreshing
Cyclic	Exchange cyclic data with Motion Control Modules. (Refreshing is
refreshing	stopped if there is a bus error.)
(See note.)
	Note: Cyclic refreshing occurs in PROGRAM mode as well.
Peripheral	Perform the following servicing if any events have occurred.
servicing	• Motion Control Module event servicing
	• Peripheral port servicing

• RS-232C port servicing

• RS-422A port servicing
