Exit code 127 usually is caused by some kind of "command not found" situation.

What is the output of
ls -ld /usr/bin/start*
ls -ld /home/root/Mod*

In startup.sh you wrote /home/root/Modbus but the file in reality is /root/Modbus

You have to correct the contents of startup.sh, isn't that obvious?
