Cloud Connectivity

If Cloud Connectivity is enabled and configured, it continually attempts to establish a connection to the MQTT broker.

The exact data volume depends on various factors, including the sampling and publishing intervals and the number of collections. Example:

With a G3/UMTS 384 kbps wireless connection, four collections with 40 variables each, a sampling interval of 100 ms and a publishing interval of 1 s, the data volume is about 300 kbps.

You can find detailed information in the application note.

If the network connection is broken, the data is retained in memory – RAM or the SD card, depending on the settings – so it is not lost. Once the Internet connection is reestablished, the data that was stored temporarily is sent.

The memory functions as a so-called ring buffer. If the network connection goes down for a longer amount of time and the memory is already completely full of data, the oldest data is overwritten.

You can find detailed information in the application note.

The PFC200 (750-8207) allows data to be sent conveniently via Cloud Connectivity over a wireless connection to Microsoft Azure or WAGO Cloud. If the monthly data volume is used up, the provider usually reduces the wireless connection speed. If the transmission speed is reduced, the PFC200 may stop sending data. Please ensure that the monthly data volume you reserve is sufficient for your application in order to ensure a stable wireless connection.

Please ensure that the e!COCKPIT WagoAppCloud library version is compatible with the firmware version.

Proceed as follows:

1. Make sure that the NTP client is configured correctly in Web-Based Management and is functioning properly. If NTP is not functioning properly, this can lead to encryption problems. Setting the time manually may also work.

2. Make sure that the IoT connection is configured correctly in Web-Based Management. Once it has been configured successfully, the PFC should establish a connection to the cloud. Please note that the IoT connection is independent of the IEC program.

3. Check the gateway settings of your network and apply the corresponding settings in Web-Based Management.

4. Check your firewall settings. The required port may be blocked (port 8883 for encrypted communication or port 1883 for open communication).

If you still have connection problems, our support team will be happy to assist you further.

Proceed as follows:

1. Make sure that your IEC program is executed correctly.

2. Make sure that the IEC variable names used do not contain any special characters or whitespace. If they do, use simple names like “energy” or “power” instead.

If you still have problems with the IEC variables, our support team will be happy to assist you further.
