Hi,
It looks like Node Red does not send any data to the OPC client. If Node Red supports OPC UA instead of OPC DA, use OPC UA.You can try setting “Read synchronously” checkbox for the subscription.
Hello,
Channel values are converted to strings automatically when displayed. If you face displaying issues, please provide screenshots.How do you transfer data between CodeSys and RapidSCADA?
By default, channel values uses Double type. If you change a channel to use Int64 type, it can help. However, it may depends on a transfer method.The channels specified in Manual Export window should be created in the Output channels table. Those channels are used to send a command from the module to the Server app.
Hi,
The idea can be:
1. If the input changes from low to high value, write a timestamp in a channel of the Calculated type.
2. Add a channel to calculate the difference between now and stored value.
3. If the input changes from high to low value, set the timestamp channel to undefined.I can answer certain questions about script syntax and available formulas. Creating complex scripts is programming, so it’s a paid service.
You can use the Hercules Utility to check connection from Windows to Linux. Use the Linux IP address and TCP port 10002.
if I simply copy and paste the whole project itself in the remote linux machine, then how to run it in that machine ?
No, because a project is converted into the runtime format before sending.
Check ScadaAgent.log on the Linux machine.Hi,
A possible reason is that TCP port 10000 has started to be used by another application, not the Server app.
Use this article for your module version.
