Enter or Modify DFA Instruction Information
Once the DFA instruction is displayed, the system prompts you to enter the
Control File Starting Address. To enter parameters into the DFA
instruction:
1. Type the Control File address and press [ENTER].
The control file must be expressed in the following manner:
For the: Use this format: Where:
PLC-5 Nfff:eee fff = an integer file between 10 - 999 and
eee = an element number between 0 - 999.
PLC-5/250 Nffff:eeee ffff = an integer file between 10 - 9999 and
eeee = an element number between 0 - 9999.
In the PLC-5/250, when you enter the control file address, the system
displays a number (1, 2, 3, or 4) in front of the address. This number
represents the logic processor in the PLC-5/250.
The PLC-5/250 chassis supports up to four logic processor modules.

Programming Software Documentation Set (publication 9313-5250).
