Manipulating Files Section 5-2
The following example shows how to use CMND(490) to create a subdirectory
in the Memory Card.
Note There are other FINS commands that can be sent to the local PLC in addition
to the ones related to file memory operations that are listed in the table above.
The File Memory Operation Flag must be used to prevent simultaneous exe-
cution of these other FINS commands, too.
5-2-4 Replacement of the Entire Program During Operation
(Not supported by CS-series CS1 CPU Units that are pre-EV1)
The entire program can be replaced during operation (RUN or MONITOR
mode) by turning ON the Replacement Start Bit (A65015). The specified file
will be read from the Memory Card and it will replace that program will replace
the executable program at the end of the current cycle. The replacement Pro-
gram Password (A651) and Program File Name (A654 to A657) must be

Operation Flag
When 000000 and A20207 are ON and A34313 is
OFF, CMND(490) issues FINS command 2215
(CREATE/DELETE SUBDIRECTORY) is sent to
the local CPU Unit and the response is stored in
D00100 and D00101.
In this case, the FINS command creates a subdi-
rectory named "CS1" within the OMRON" directory
in the CPU Unit's Memory Card. The response is
composed of the 2-byte command code (2215) and
the 2-byte response code.
