UNILINK HOST ADAPTER 1–6
USER MANUAL
The flexibility of the UNILINK Host Adapter also provides for multiple hosts as
illustrated in Figure 1–6. In addition to the process control application, your
main plant system can link to the same network to track work-in-progress,
adjust schedule loads for peak efficiency, and collect product cost data. With an
additional UNILINK Host Adapter, you can also add a personal computer
workstation to the network for statistical quality control or other uses.
