Assigning Expansion Instruction Function Codes
This operation is used to display or change the expansion instructions
assigned to expansion instruction function codes. The assignments can be
displayed in any mode, but can be changed in PROGRAM mode only.
Assign expansion instruction function codes before inputting the program. The
CPM2B will not operate properly if expansion instructions aren’t assigned cor-
rectly. An expansion instruction can be assigned to one function code only.
The PLC Setup must be set for user-defined expansion instruction assign-
ments. Set bits 8 to 11 of DM 6602 to 1 and turn the PLC’s power OFF and
then ON again to enable the new setting.
There are tables in SECTION 5 Instruction Set showing the default function
code assignments in the CPM2B.
