*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.
Setting Procedure of External Device
The following procedure shows how to assign
the device in the RSLogix5000 software and specify the address in BLUE.
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.

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. |
