*1 The following CPUs are accessible:
Q12DCCPU-V with a serial number of which first 5 digits are "12042" or later
Q24DHCCPU-V, Q24DHCCPU-LS, Q24DHCCPU-VG, and Q26DHCCPU-LS
*2 Q00JCPU is not accessible.
*3 The following CPUs are accessible:
Q12DCCPU-V (Extended mode),
Q24DHCCPU-V, Q24DHCCPU-LS, Q24DHCCPU-VG, and Q26DHCCPU-LS
*4 To directly access link devices, access them as link direct devices (J\) depending on network module specifications. An access
target device varies depending on a device number to be specified. Therefore, a device number which is actually accessed may be
different from the specified device number.
For specification method for accessing link direct devices (J\) using MELSEC data link functions, refer to the following:
