ASupported PLCs
Application Notes
A.1 Allen-Bradley PLC 5, SLC500 and
MicroLogix PLCs
Registers Accessed
The DTU3005 will only access registers in integer files
in the PLC memory (N file types). When specifying
register numbers in the DTU3005 Editor Program, the
file number is entered into the File field, and the ele-
ment number within the file is entered into the Regis-
ter field. Initial register number is 0.
Protocols Supported
The DTU3005 uses the DF1 protocol, which is also
known as Full Duplex or Point-to-Point. It supports
both the CRC and BCC methods of error checking.
Please note that the MicroLogix PLC only supports the
CRC method of error checking. Therefore, when using
a MicroLogix PLC, the protocol selected on the port
configuration screen in the DTU3005 Editor software
must be “AB SLC500 (CRC)”.
A.2 GE Fanuc 90/20, 90/30 and 90/70
PLCs
Registers Accessed
The DTU3005 will only access registers in the Data
Register Area of PLC memory (%R1 to %R9999). When
entering register numbers, only the offset into this
area (1-9999) should be entered. For example, to
access register number %R1, the value 1 should be
entered. To access register number %R9999, the value
9999 should be entered.
A.3 Idec Micro-3 PLCs
Registers Accessed
The DTU3005 will only access registers in the Data
Register Area of PLC memory (D0 to D9999). When
entering register numbers, only the offset into this
area (0-9999) should be entered. For example, to
access register number D1, the value 1 should be
entered. To access register number D9999, the value
9999 should be entered.
Link Adapter Requirement
The DTU3005 requires an Idec Link Adapter or equiva-
lent to be used when communicating with any of the
FA Series PLCs.
A.4 Idec FA Series PLCs and Square D
Model 50
Registers Accessed
The DTU3005 will only access registers in the Data
Register Area of PLC memory (D0 to D9999). When
entering register numbers, only the offset into this
area (0-9999) should be entered. For example, to
access register number D1, the value 1 should be
entered. To access register number D9999, the value
9999 should be entered.
Link Adapter Requirement
The DTU3005 requires an Idec Link Adapter or equiva-
lent to be used when communicating with any of the
FA Series PLCs.
A.5 Koyo/PLC Direct 205 Series PLCs
Registers Accessed
The DTU3005 can access all register types in the 205
Series PLC through the use of the V-Memory assign-
ments shown in the following table:
