TCL/TK BASED API FOR OMRON'S RS485 INTERFACE NETWORK

This paper describes one application of the script language Tcl/Tk for building of OMRON'S RS485 interface networking API (Application Program Interface). In the article are considered several topics: OMRON'S RS485 interface specification, networks realization using this interface,Omron application commands set, building of API as TCL/TK extension for Win95/98/NT and Tcl/Tk technique using for API realization. It's present the data base logical structures too. The developed software can be included in different projects, based on RS485 interface, realizing distributed process control system. The extension is designed according to Free Source License of GNU-groups.
