FINS Commands Section 5-3
Parameter Areas
The areas that can be written to are shown below, along with their parameter
area codes.
Data (command)
Set to 0000. The number of words to be cleared is specified by the number of
words in the command format. This parameter has two bytes (one word) of
data.
End code (response)
Refer to 5-1-3 End Codes for information on end codes.
Comments The PARAMETER AREA CLEAR command can be executed regardless of
the CPU Unit’s mode. It is the user’s responsibility to program steps to prohibit
this command from being executed when the CPU Unit is in the RUN mode if
such protection is necessary. Execute CPU UNIT STATUS READ (command
code 0601) to read the CPU Unit’s mode. (Refer to 5-3-17 CPU UNIT STATUS
READ: 06 01.)
Data can only be cleared from the I/O registration table when the CPU Unit is
in PROGRAM mode. When data is cleared from the I/O registration table for
CJ-series CPU Units, the CPU Unit enters the status where I/O is automati-
cally allocated at power-ON and the status of mounted Units is reflected in the
I/O registration table. It is not simply cleared to 0000 hex.
Each parameter area must be cleared in its entirety.
5-3-10 PROGRAM AREA READ: 03 06
Reads the contents of the specified number of consecutive program area
words starting from the specified word.
