I believe Nginx must be better but since somehow mono-xsp4 available on my Ubuntu system:

PART 1: mono-xsp configuration

1. Copy /etc/init.d/mono-xsp4 as /etc/init.d/scada-xsp4 and modify it:

sudo cp /etc/init.d/mono-xsp4 /etc/init.d/scada-xsp4
sudo nano /etc/init.d/scada-xsp4

#! /bin/sh
### BEGIN INIT INFO

test -x $DAEMON || exit 0
test -f $DEFAULT && . $DEFAULT	

if [ "x$start_boot" != "xtrue" ] ; then
    exit 0
fi

if [ ! -e $MONO_SHARED_DIR ]; then
	mkdir $MONO_SHARED_DIR   
	chown $user:$group $MONO_SHARED_DIR
fi
                
should_start() {
    if [ ! -e $VIRTUALFILE -o <code>cat $VIRTUALFILE | wc -l</code> = "2" ]; then
	log_action_msg "You have an incomplete $VIRTUALFILE"
	log_action_msg "To fix it, you need to install at least one package for xsp4 (like asp.net-examples)"	
	return 1

	    return 1		
	fi
    fi
    
    return 0
	
}

case "$1" in
    start)
	if should_start ; then
	    log_daemon_msg "Starting $DESC" "$NAME"
	    export MONO_SHARED_DIR

	N=/etc/init.d/$NAME
	echo "Usage: $N {start|stop|restart|force-reload}" >&2
	exit 1
	;;
esac

exit 0

2. Copy /etc/default/mono-xsp4 as /etc/default/scada-xsp4 and modify it:

sudo cp /etc/default/mono-xsp4 /etc/default/scada-xsp4
sudo nano /etc/default/scada-xsp4

# Defaults for mono-xsp4, official version
# sourced by /etc/init.d/scada-xsp4

# Should we start it?
start_boot=true

# User and group by default
user=www-data
group=www-data

# Default port
port=8000
address=0.0.0.0

# Directory for config files
config_files=/etc/scada-xsp4

3. Copy /etc/xsp4/debian.webapp as /etc/xsp/scada.webapp and modify it:

sudo cp /etc/xsp4/debian.webapp /etc/xsp4/scada.webapp
sudo nano /etc/xsp4/scada.webapp

<apps>
  <web-application>
    <name>scada</name>
    <vpath>/</vpath>
    <path>/opt/scada/ScadaWeb</path>
  </web-application>
</apps>

4. Activate scada-xsp4 service and start it:

cd /etc/init.d/
sudo chmod +x scada-xsp4
sudo update-rc.d scada-xsp4 defaults
sudo service scada-xsp4 start

5. Open http://localhost:8000 on your browser for testing

[kumajaya]

https://store.chipkin.com/products/tools/cas-modbus-scanner has a feature to scan available device address.

[kumajaya]

Why not just set it as a virtual com port using https://www.waveshare.com/wiki/File:USR-VCOM_V3.7.1.520.7z and test the communication using a Modbus tester application first.

[kumajaya]

I just want to confirm GrafanaDataProvider works good so far. Please remember to release official build.

[kumajaya]

Usually I use a Modbus tester application to confirm Modbus RTU/TCP communication. You can try https://store.chipkin.com/products/tools/cas-modbus-scanner or https://github.com/ed-chemnitz/qmodbus

[kumajaya]

Let me try it, I’ll report back later. Big thanks.

[kumajaya]

I found GrafanaDataProvider not maintain the connection to Rapid SCADA server but make a new connection in every Grafana request. Sometime fail to connect to server if request too often, for example, multiple panel in a dashboard will make a multiple requests in every Grafana refresh. Sometime no data response back because fail to connect to RS server.

[kumajaya]

Not found yet but logically incorrect.

[kumajaya]

@greenfoxx @Mikhail Please check https://github.com/kumajaya/scada-community/commit/46d9f43fc3ee0b37b65c83cfa337af63a0fd4b4b

[kumajaya]

Great! Very proud if I could contribute back to Rapid SCADA. BTW, RS need a better logo 😀

[kumajaya]

I just confirmed it. Now I really got five data for last five minutes time range. Thank you.

But I have a different experience on Linux, Ubuntu 20.04 LTS. Sometime Grafana just shown no data. I have to debug it further, installed this modul on both Windows and Linux, RS running on Linux.

[kumajaya]

I can connect with every security level supported by the server using above official client.

[kumajaya]

I can connect with every 7 combination supported by Node OPCUA from UaExpert dan Prosys including “None and None” but only “Sign & encrypt and Basic256Sha256” with KpOpcUa. No problem, I can connect to Node OPCUA server now without modified source code.

[kumajaya]

Oh my bad… Sign & encrypt and Basic256Sha256 is the only security mode and policy accepted by my Node OPCUA server. Let me check further what’s exactly the problem.

[kumajaya]

OK. I’ll check it.
