Operation Memory Area - Panasonic FP7 Series User Manual

8.1 CPU Unit Specifications
(Note 3) The LAN port is insulated from the internal circuit.
(Note 4) MC protocol is an abbreviation for MELSEC Communication Protocol, and MELSEC is a registered
trademark of Mitsubishi Electric Corporation. Only QnA compatible 3E frame and binary (bulk read and
bulk write) can be used.
(Note 5) The standards cite 100 m as the maximum, but noise resistance measures such as attaching a ferrite
core may be necessary in some cases, depending on the usage environment. Also, if the hub is
positioned close to a control board, we recommend using it at a distance of 10 m or less.

(Note 1) Turns on or off based on external input.
(Note 1)
Externally outputs on or off state.
(Note
Relay which turns on or off only within
program.
(Note
This relay is a shared relay used for PLC
link.
This goes on when the timer reaches the
(Note 2)
specified time.
(Note 2) This goes on when the timer increments.
Relay which turns on or off based on specific
conditions and is used as a flag.
This relay only turns on during one scan at
the start of the execution condition.
This relay ensures that error conditions that
are freely allocated by the user are
memorized in the memory.
This relay is for input/output processing
during operation, without depending on
usual I/O refresh.
Code for specifying 16 external input points
as one word (16 bits) of data.
Code for specifying 16 external output points
as one word (16 bits) of data.
Code for specifying 16 internal relay points
(Note 2)
as one word (16 bits) of data.
Code for specifying 16 link relay points as
one word (16 bits) of data.
Data memory used in program. Data is
handled in 16-bit units (one word).
