Application Notes – PLCs and Devices
SQUARE D MODEL 100-700 PLCS
Registers Accessed
The DN-3000 will only access registers in the Data Area of PLC memory (S0 to S9999). When entering register numbers, only the offset into this area (0-9999) should be entered. For example, to access register number S10, the value 10 should be entered. To access register number S999, the value 999 should be entered.
SQUARE D TSX07 PLCS
Registers Accessed
The DN-3000 will only access registers in the Memory Word Area of PLC memory (%MW0 to %MW999). When entering register numbers, only the offset into this area (0-999) should be entered. For example, to access register number %MW0, the value 0 should be entered. To access register number %MW999, the value 999 should be entered.
TI505 SERIES PLCS
Registers Accessed
The DN-3000 will only access registers in the V Area of PLC memory (V1 to V9999). When entering register numbers, only the offset into this area (1-9999) should be entered. For example, to access register number V1, the value 1 should be entered. To access register number V9999, the value 9999 should be entered.
Passthrough Port Note
When using TISOFT PLC programming software on the passthrough port (Port 3) of the DN-3000, the software must be invoked with the following parameters:
p1 | T0 | 0 | (for PC COM Port 1) | OR |
p2 | T0 | 0 | (for PC COM Port 2) | |
For example, if you are using a 545 PLC and you are using COM2 on your PC, you would invoke TISOFT as follows:
TI545 p2 T0 0
These parameters will prevent the programming software from switching over to the Transparent Byte Protocol, which is not supported by the DN-3000.
