Communications
Using C3Server
C3Server is a Win32 application that manages the communications between the PC and the Contro3(s). It uses the PC’s serial com port , which would be wired through an RS232/422 converter to one or two Contro3.
C3Server has the following features;
  • Manages the communications through a protocol, which provides protection for the data against transmission errors.
  • The protocol used is a multi-drop protocol, which allows the server to manage communication with more than one device along a single 485 wire.
  • C3Server is linked through the Borland Database Engine (BDE) directly to the database tables where the data is stored. Therefore each data record received is immediately posted to the database.
  • C3Server acts as a data server to the Contro3, sending data records down to the Contro3 in response to its requests.
  • C3Server is a deamon application, which means it is intended to run in the background in an on-line configuration without requiring any user intervention. However it can also be run as a batch application without any loss of functionality.
  • C3Server creates several log files which can be used for troubleshooting and data recovery.
