Set the occupied station count for the number of connected
modules set in the Station information settings.
Change the number of modules to be monitored to the number of
modules currently mounted and execute monitoring.
Change the number of test target modules to the number of
modules currently mounted or less and conduct the test.
Terminate the parameter reading/writing/verifying from another
utility (C Controller setting utility, CC-Link utility, MELSECNET/H
utility, or CC IE Control utility) and then reexecute.
Check if parameters have been set for the number of modules
set on the Parameter settings screen.
Set 8 points to each of remote stations in pair in the Station
information settings.
Set the receive buffer size in the Station information settings to 0
or within the range of 64 to 4096.

within the range of 64 to 4096.
Change one or more reserved station settings in the Station
information settings to "No setting" or "Invalid station".
Set the start I/O No. within the range of 0 to 0FE0.
Verify the start I/O No. of the mounted modules set on the
Parameter settings screen for duplicated numbers, and correct
the setting if any duplication is found.

Station information settings.
Set a station type.
Set the target CPU No. within the range of 1 to 4.
Make setting so that the station type data in the Station
information settings satisfies the conditional expression {(16XA)
+ (54XB) + (88XC) } <= 2304 (A: No. of I/O stations, B: No. of
device stations, C: No. of intelligent stations).
Adjust the auto buffer size total in the Station information settings
to 4096 or less.
In the Station information settings, adjust the number of
