Product Condition

I confirmed that it works properly. We are checking the following.
- After connecting A2ACPU + AJ71AR21 and A2USHCPU + A1SJ71AR21 with a coaxial cable and configuring a network, link devices (link memory, link register, XY) can be shared normally between both stations.
- By monitoring the link special relay, check that communication on both the primary loop and secondary loop lines is normal, and that hardware error detection is OFF (normal).

Year of manufacture: 2000 Version: HM
