A new algorithm for connecting between LOGO and labview software

One of the levels of automation pyramid is monitoring level. Today makers of industrial controllers such as PLC or DCS, usually create monitoring for large industrial controllers with hardware modules by HMI card. For small industrial controllers such as miniPLC or ARM, this ability has not been created. For example, siemens cooperation for MiniPLC-LOGO only has been developed one text display to market and there wasn't capability of monitoring. By regarding that for low I/O, the use of MiniPLC is not expensive, so we use monitoring system for automation of a process.In this paper for the first time by using of an algorithm in labview software, all data have been received in HEX form and after that by decoding of information, all inputs and outputs have been monitored. Results of this research have been applied for SINTECH KHAZAR electro-motor making cooperation.
