Abstract:

kW transmitter control system is designed with PLC as the core controller according to actual control requirements. The hardware design of the system is described and the soft ware design based on an integrated development environment is introduced in detail. Then after the laboratory test and field test, the system has realized the switch on the transmitter control, real-time data monitoring, fault analysis and processing, recording historical information and query, parameter settings and other functions. It can meet all control requirements of transmitter, and has a powerful remote control ability and human-computer interaction ability , also with good reliability and real-time.
