“It is difficult to know exactly what the problem is until you visit the site, so we cannot prepare adequately, and our customers have to shut down their equipment until our visit. In addition, parts may need to be arranged after visiting the site, which further delays repair. In the past, some customers had to stop their operation for several days. To improve this maintenance system and avoid shutdown, we discussed the possibility of implementing remote access to identify problems before visiting sites. With such a system, operation could be restored sooner, contributing to the stability of customer facilities."
