interoperability, compliance and reliability. IOP workshops also provide an ideal opportunity to network with your peers, learn about OPC technology and interact with industry-leading experts. The workshop will be hosted by Honeywell in Phoenix, Arizona from April 20 through 24. Details and registration.
