qwert Posted December 5, 2016 Share Posted December 5, 2016 hello , i'have logging data using the "ASCII delimited" using protocol "mod-bus tcp-IP" and time out is 1000,...using this i communicate plc and scada successfully . my first question is that if i remove the communication cable then after the graphical representation is not changing means that scada representing healthy graphical representation instead of cross marking representation.linking my second question is that after removing this cable i want data logging in .csv format which is working o.k but in data logging it holds last value which i don't want. for example,if communication cable is inserted the data logged values are 12,13,11,0 and at the time of removing communication cable if at that time last value is 13 then it will continue log data 13 means it holds last value.but i want if communication breaks than then doesn't hold last value.
