Product Condition

I have confirmed that it works properly. We are checking the following:
・Connect A2ACPU+AJ71AR21 and A2USHCPU+A1SJ71AR21 with a coaxial cable to configure a network, and link devices (link memory, link register, XY) can be shared normally between both stations.
・By monitoring the link special relay, it is confirmed that the communication of both the main loop and the sub loop is normal, and that the hardware abnormality detection is OFF (normal).
