Description

Hi, I am trying to use PLC4x (PLC4J actually) and find some errors:

1. When I used `HelloPlc4x`, the clioption was: --connection-string test://127.0.0.1 --field-addresses RANDOM/foo:BYTE 

        OK it works!

 

      2. Then I tried org.apache.plc4x.java.examples.integration.edgent.PlcLogger, and the cliOption was: --connection-string test://127.0.0.1 --field-address RANDOM/foo:BYTE --polling-interval 1000, then error occurs:

I tried some other data type like INTEGER, and got the same error.

 

Is there something wrong?
