*1: Once a value has reached the upper limit, logging files are moved to a
different file and the graph display is cleared. Samples may not be created to
a maximum depending on environment factors such as the PC load and the
number of modules.
*2: Data sampling may not be performed in accordance with the monitor cycle
setting, depending on environment factors such as the PC load and the number
of modules.
The recommended monitor cycle settings for specific module numbers are
shown below.
Recommended settings:
(For Ethernet communication)
1 module
: 400 msec
2-4 modules
: 1 sec
5-16 modules
: 2 sec
17 modules or more : 4 sec
(For loader jack communication)
2000 msec
*3: These are the settings for loader communication (Ethernet and serial).
(The parameter read/write timeout values are fixed at Ethernet: 50 sec and
Serial: 40 sec)
