-------------------------------------
Summary: Problem when using examples/hello-integration-edgent with
plc-simulator
Key: PLC4X-146
URL: https://issues.apache.org/jira/browse/PLC4X-146
Project: Apache PLC4X
Issue Type: Bug
Components: Integration-Edgent
Affects Versions: 0.6.0
Reporter: Xiangdong Huang
Hi, I am trying to use PLC4x (PLC4J actually) and find some errors:
# 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?
