DELPHI编程实现与多台变频器的RS485通信控制

THE REALIZATION OF COMMUNICATION CONTROL BETWEEN ONE COMEUTER AND RS485 OF SEVERIAL TRANSDUCERS WITH DELPHI PROGRAM

在工业控制中经常需要用到微机与其它设备的串行通信,作者在文中介绍了利用DELPHI编程实现WINDOWS环境下单台微机与多台西门子MicroMaster变频器的RS485串行通信控制,并以此说明了微机与其它串行设备通信的一般性问题。

It often need the serial communications between computers and other equipments in industrial controls. This text introduces how to use DELPHI programming to realize a computer communication with transducers of SIEMENS MicroMasterl in RS485 protocols under the WINDOWS environment. So as to explain the generalities of the computer communication with other serial equipments.
