Transfer Of Continuous Logging Data - Mitsubishi Electric MELSEC iQ-R User Manual

Transfer of continuous logging data

Logging data can be transferred into file registers (ZR) of the CPU module by using following items.
• Function block for continuous logging data transfer (M+R60ADH_ReadContinuousLogging)
• Interrupt function
Transfer of data with the function block
The function block for continuous logging data transfer continuously transfers logging data into file registers (ZR) of the CPU
module in the storage order of logging data (A side  B side  A side ). Set the number of data sets to be transferred into
the CPU module considering the capacity of file registers of the CPU module in use.
