Product Condition

We have confirmed that it works properly. We have checked the following:
- After connecting the "A3UCPU", "AJ71LP21", "A2USHCPU-S1", and "A1SJ71LP21" with optical cables and configuring a network, link devices (link memory, link register, XY) can be shared normally between both stations.
· By monitoring the special link relay, it is possible to verify that communication on both the forward and reverse loop lines is normal and that hardware error detection is OFF (normal).
