Task
Our customer, a Japanese automotive supplier, uses autonomous mobile robots (AMRs) to deliver materials to employees’ workstations. This significantly reduces walking distances and saves time.
To ensure that AMRs and employees can work together safely, a fail-safe wireless connection to the manual emergency stop switches is required—transmitted via the CIP Safety protocol. Without this reliable safety communication, the planned process automation cannot be implemented.
Implementation
R3 Solutions provided a replicable and scalable, locally oriented wireless network solution and integrated the emergency stop buttons via the CIP Safety protocol. The network connection operates with low latency and no downtime.
Result
This highly reliable wireless solution enables the secure integration of AMRs and thus the desired process automation. This makes it possible to design the specific manufacturing process much more efficiently—while fully complying with safety requirements.
