1-2-2 Versatile Functions
Memory Card and File Management Functions
Transfer Data to and from
Memory Cards
Data area data, program data, and PLC Setup data can be transferred as files
between the Memory Card (compact flash memory) and a Programming
Device, program instructions, a host computer, or via FINS commands.
Convert EM Area Banks to
File Memory (CJ1-H and
CJ1 CPU Units Only)
Part of the EM Area can be converted to file memory to provide file manage-
ment capabilities without a Memory Card and with much faster access time
than a Memory Card. (The EM Area can be very useful for storing data such
as trend data as files.)
Automatic File Transfer at
Start-up
The PLC can be set up to transfer the program and/or PLC Setup files from
the Memory Card when the PLC is turned ON. With this function, the Memory
Card provides a flash-ROM transfer. This function can also be used to store
and change PLC configurations quickly and easily.
Network 3
Network 2
Network 1
Remote programming/monitoring of a PLC on a network up to
3 levels away (including the local net-work) for the same or
different types of networks is possible through Host Link.
Network 1
Network 2
Network 3
Message transfer between PLCs on a network 3 levels away (including
the local network) for the same or different types of networks.
Seamless message communications are possible across Ethernet, Controller Link, and DeviceNet networks,
enabling easy information integration on machine, machine-to-machine, and machine-to-host levels.
I/O Memory, program,
and parameter areas
stored as files.
