*1 Access units differ depending on the module type. When data inconsistency is a problem, select "Single Handshake" or "Multiple
Handshake" for a trigger condition.
*2 For access without using an Ethernet port of an RD81MES96N
*3 For access by using an Ethernet port of an RD81MES96N
Precautions
When accessing the device memory in device tag component units, device values may be obtained from multiple sequence
scans and applied, which may cause data inconsistency.
When data inconsistency is a problem, refer to the following:
