Configuring DFA Instructions
5-8
When the control file address is entered, the system prompts you to
enter the number of I/O. Valid entries of I/O are 8, 16, or 32.
Important: The control file address must be local to the logic processor
executing the associated DFA instruction. Do not place this file in system
memory.
2. Type the number of I/O you are using and press [ENTER].
The system prompts you for the program file number. The program
file number refers to the number of the DFA CAR file in the online
or offline program directory.
3. Type the DFA CAR program file number and press [ENTER].
In the PLC-5 processor, the system displays the I/O Definition
screen. If you have a PLC-5 processor, continue with “Enter or
Modify Input Information” on page 5-9.
In the PLC-5/250 processor, the system prompts you for the Message
Control Block address.
4. If you have a PLC-5/250 processor, type the Message Control Block
address and press
[ENTER].
The Message Control Block address must be entered in the following
manner:
0MSGX:X
where:
0 is the Resource Manager global memory (must be set to zero)
X:X
message control block number (0-9999)
file number (0-9999)
For example, 0MSG0:0 is a valid control block address.
The system displays the Input Definition screen (see the figure on the
next page).
