AB CompactLogix/ControlLogix Series (DF1) Driver
Note 1 Take N_ BOOL 112087.12 as example, the first three number 112 is the File Number, and 087.12 is the
Variable No. Address. The blanks before the Variable No. Address less than three digits should be filled
with 0.
2 The File Number can be customized by the user.
3 INT000000~254254 indicates that the range of the File Number is 0 to 254 (the first 3 digits), and the
Address Range of the variable is 0 to 254 (the last 3 digits). If 001255 is input, a dialog box “over read
address” will pop up, requesting the user to input again.
AB MicroLogix Series Ethernet (TCP Slave) Driver
*1 When the address is less than three digits, it should be filled with 0 to be three digits.
Example: When 113 refers to File number 113 and 10.12 refers to Address 10.12, specify to 113010.12.
