*1When you write the bit address, the Display reads the word address corresponding to that of the External Device first. Change only the target bit address among the word data once read, and write the word data to the External Device.
Note that the correct data may not be written if you change the word address value in the ladder program while the Display reads the data of the External Device and writes it to the External Device.

*2To access those addresses and use them in the program of the External Device, you need to set the External Device first.

*3The maximum length of the STRING device is 82 bytes.

 

The following procedure shows how to assign the device in the RSLogix5000 software and specify the address in BLUE.

  1. Tag setting of External Device
    Create the Tag Name in the RSLogix5000 software, and set the Type. Map the created Tag Name to a File Number.

Tag Name

:Set optionally.

Type

:Select the data type among below to set the Element.

  Match the device name of BLUE

 BOOL(32bit data type)

 INT(word data type)

 DINT(dword data type)

 SINT(byte data type)

 REAL(float data type)

Set the range used in BLUE for the Element. Maximum Element BLUE can access is 999.

When you do not define the Element, only one item is available to use.

(Example) Tag Name: N8, Type: When INT is set, only one word of N8 can be used.
<Example1>

Tag Name

Type

N7

INT[200]

DINT1

DINT[100]

DATA2

SINT[50]

1st line: Tag Name"N7" is INT data type with Element 200

2nd line:Tag Name "DINT1" is DINT data type with Element 100

3rd line: Tag Name "DATA2" is SINT data type with Element 50

 

File Number

: Assign the Tag Name created by RSLogix5000 to the optional File Number.
 You can not assign different Tag Names to the same File Number.
