1: Note that the number of intelligent function module parameters that
may be set for automatic refresh setting is limited.
The number of parameters that may be set for automatic refresh setting
is as follows.
Sum total of the numbers of parameters within the setting ranges of all
intelligent function modules
If the number of parameters set exceeds the limited number, the
remote I/O module detects the "SP. PARA ERROR (3301)" error.
POINT
(1) If automatic refresh settings are performed by the intelligent function module
parameters in the remote I/O module, do not use device X,Y in the PLC-side
device.
If these are incorrectly used, the network will not operated properly.
In the same manner, do not use device X,Y in the CC-Link refresh settings with
the remote I/O module network parameters.
(2) If the error has been detected, read/write the data of the intelligent function
modules using the REMFR/REMTO instruction.
The number of parameters for automatic refresh setting is preset to each
intelligent function module.
To confirm the numbers of parameters for automatic refresh setting, refer to the
user's manuals of the corresponding intelligent function modules.
REMARKS
Refer to the manual for the intelligent function module for details about the method
for setting the intelligent parameters.
