In these cases, EHM system performance can be improved by combining wired and wireless technologies. The DXM1200-X2 wireless IIoT gateway mentioned above includes Modbus wired connectivity. If Ethernet is needed, designers can turn to the DXMR90-X1. The DXMR90-4K can implement IO-Link master/ controller functions. In addition to the choice of Modbus, Ethernet, and IO-Link, designers can use the R709 serial data radios to provide wireless connectivity to physically dispersed assets (Figure 4). ISO 10816 vibration severity ISO 10816 is an important standard for EHM systems. It quantifies vibration severity for machines
