We confirm only D4-440 address range. Depending on the type of PLC that you will be using,
the there are limits to the areas that can be used within the device ranges given above. Refer
to the PLC manual for details.
When selecting Bit Write, operation depends on the project settings which has an option to
turn off all other bits in the byte or leave all other bits without change. Check or uncheck the
check box for "Bit Write operation will write to a byte." (Byte refers to 8 bits.)
Check: When executing Bit Write, all other bits in the byte are turned off. Uncheck:
When executing Bit Write, all other bits are not changed. During Bit Write operation, the
MICRO/I reads the byte data including the designated bit from the PLC, performs logical
AND or OR operation with the designated bit, and writes the result into the PLC, therefore
all other bits in the byte are not changed.
