S7-1513 Send data to rmc150,In the plc,the data does not include 0.0,but in the rmc150 ,by plot(10ms sample interval) ,I find that the data Often appear 0.0

1:I checked the communication,the error event does not appare the communication error in the rmc150 and s7-1513
2:i update the firmware to the 3.68

I cant find the reason why the data in the rmc suddenly change 0.0

One additional troubleshooting tool is the Event Log. To use it, do the following:

  1. In the Project pane, right-click Event Log and choose Properties.
  2. Choose the Communications folder.
  3. Click 10/100 Ethernet.
  4. In the Ethernet I/O Logging box, choose All.
  5. Click OK.

Now, the Event Log will record all the incoming data each time the incoming data changes. This may help in figuring out the problem.
