| Abstract: |
| According to the security requirement during producing and storing flammable
and explosive medium, a solution about environment parameter acq
uisition system based on PROFIBUS-DP is proposed. The system structure
and controll
ing process are designed.The network communication protocol of system is describ
ed in combination with PROFIB
US-DP open location bus.The CPU and I/O module of S7-200 series are used as a lo
wer computer and an independent MCGS as a upper monitoring computer to realize c
entralized management and real-time monitoring of the collected data.The practic
al o
peration proves that the system has stable performance, high reliability and pro
cess automation efficiency,so the design objectives are achieved. |
