DATA Logging

I need to record some value within the PLC, at an interval. I am using a S7-2xx plc. I have heard Microwin 4, has some features for DATA LOGGING, but my microwin 4.0 is 2-3 weeks away from me.

meanwhile I would like to get more information, as to achive this conveniently.

Please point me to a function/idea, and I will come back with more questions.

regards.

I am not familiar with them.

Here is a "LINK" to Entertron, who makes PLC's and other nifty stuph, like the "Logger". "LoggeR Link", you can download the manual for the "Logger" from the Logger link I posted. They have great tech support (which is FREE).

Sorry for the confusion, I meant DATA loggin, within the PLC, so that it can be forwarded to a HMI or to a PC monitoring it.

I just want to know how to manuplate data within the memory blocks, I would have 10 types of data (each DOUBLE WORD), if I trigger it every 1 hour, this would mean 80 Double words per shift, based on two shifts per day into 3 days backup would mean moving 480 DWs.

This massive movement of DWs, I have never come accross with.
I'd appreciate if someone shed light on this.

REgards,

You can use FIFO command for your 10 variables so you have ten FIFO. Each FIFO can hold up to 100 values.
