| Abstract: | This paper introduces the design of multi-state supervisory field data acquisition system with PHOENIX RS422/485 - PRO module as the core for freeway tunnel. The field data are acquired and exchanged with computer and realized real-time display by using programmable logic controller （PLC）. In the PCWORX , corresponding function blocks is used for setting communication proto- col and other communications parameters. Through in-situ test, it is demonstrated that the module has the features of flexibility and practicability in the multi-state supervisory system for expressway tunnels. |
