Structured programmingProgram standardizationSimplification of program

Structured program Structured program managementmanagement

Up to 124 of parameter, program, comment and device data files can be created and loaded into the CPU’s built-in memory and/or IC card memories.

Capability to handle multiple program files makes each program smaller so that maintenance and debugging of the programs can be easier.

M100

Because M0 is a local device, M0 in Program A and M0 in Program B can operate independently.Because M100 is a global device, status of M100 in Program A is relayed to M100 in Program B.

Note: Range of each device type as local device can be defined by the user

Structured program Structured program managementmanagement

Global device & Local device– Local devices can be assigned in the following

devices Internal relay M Edge relay V Timer T Retentive timer ST Counter C Data register D

Macro command– A program block often used in a program can

be registered as a user-defined macro command

Subroutine call with arguments– A subroutine program can be called from

another program with input arguments and output arguments, similar to ‘function call ‘ of C language.

Device initial data– QnA can hold a device initial data file where

initial setting data of devices are registered, and transfers this data into device memory when the CPU is set to RUN.

The bus switching module A6RAF switch the I/O bus from the hot CPU to the stand-by CPU when the system control module detects either of:

CPU's self-diagnostic error (reported by the CPU itself), or

the CPU stops to reset the WDT in the system control module.
