Dip Switches Nel Cj1m

[dvx70]

Qualcuno potrebbe dirmi quali sono le funzionalità di tutti i dip switches del CJ1M.

So che il 2 attiva la memory card, il 4 attiva il Sysmac Way, ma gli altri ?

Ho cercato sul manuale della CPU e su quello di programmazione, ma non ho trovato nulla.

Grazie in anticipo.

Pin Function Setting Description

1 Write-protection for

user program

memory (UM) (

See note 1.)

ON Write-protected User program memory is write-protected when this pin is ON.

Turn ON to prevent the program from being changed accidentally.

OFF Read/write

2 Automatic transfer

of the program at

start-up

ON Yes The program (AUTOEXEC.OBJ) and PC Setup

(AUTOEXEC.STD) will be transferred from the Memory Card to

the CPU Unit automatically at start-up when this pin is ON. (See

note 4.)

A PC’s software (program and PC Setup) can be completely initialized

just by inserting a new Memory Card and turning on the

power. This can be used to switch the system to a new arrangement

very quickly.

Note When pin 7 is ON and pin 8 is OFF, reading from the

Memory Card for easy backup is given priority; even if pin

2 is ON, the program will not be automatically

transferred.

OFF No

3 Not used. --- --- ---

4 Peripheral port

communications

parameters

ON Use parameters

set in the PC

Setup.

• Leave this pin OFF when using a Programming Console or

CX-Programmer (peripheral bus setting) connected to the

peripheral port.

• Turn this pin ON when the peripheral port is being used for a

device other than a Programming Console or CX-Programmer

(peripheral bus setting).

OFF

(default)

Auto-detect Programming

Device

(See note 2.)

5 RS-232C port communications

parameters

ON Auto-detect Programming

Device

(See note 3.)

• Leave this pin OFF when the RS-232C port is being used for

a device other CX-Programmer (peripheral bus setting) such

as a Programmable Terminal or host computer.

• Turn this pin ON when using CX-Programmer (peripheral bus

setting) connected to the RS-232C port. OFF

(default)

Use parameters

set in the PC

Setup.

6 User-defined pin ON A39512 ON The ON/OFF status of this pin is reflected in A39512. Use this

function when you want to create an Always-ON or Always-OFF

condition in the program without using an Input Unit.

OFF

(default)

A39512 OFF

7 Easy backup setting

ON Writing from the

CPU Unit to the

Memory Card

Press and hold the Memory Card Power Supply Switch for three

seconds.

Restoring from

the Memory

Card to the CPU

Unit.

To read from the Memory Card to the CPU Unit, turn ON the PC

power.

This operation is given priority over automatic transfer (pin 2 is

ON) when power is ON.

7 Easy backup setting

OFF

(default)

Verifying

contents of

Memory Card.

Press and hold the Memory Card Power Supply Switch for three

seconds.

8 Not used OFF

(default)
