Programming Examples
Examples Using
Direct
LOGIC PLCs
The OP--WINEDIT configuration software allows you to configure a panel to use a
block of registers at a starting value that you define. For a DL05, DL105, DL205,
D3--350 or DL405 CPU the recommended memory to use is the general purpose
data words starting at V2000. For the 305 family (except the D3--350) the
recommended memory is the registers beginning at R400. Any block of registers
within the data word range can be used.
The first eleven PLC registers in the block used by the OP--640 panel are used for
numeric information, and this makes them ideally suited for the general purpose
data registers. The M+12 and M+13 registers use individual bits for pushbutton
status and light control, making it better suited for the control relay register range of
memory. The solution to this minor conflict is to define the base register address in
general purpose data register memory and place a rung in your PLC program to
copy the last register to a control relay register (we show you how to do this later).
