Hello,
Is it possible to put null or delete value in data table in micrologix?
Micrologix is using modbus to get data and store it in integer (N) data file. Then data is read by rslinx. If modbus communication fail data in file remain unchanged so in rslinx (and further in my application) i get old data which i simply don't want to have because its hard to spot when there was communication lose and when data was simply static. I prefere to have empty fields - it will not populate my database with false data and allow to notice communication error faster.
