Hello,

Currently, the best way is to find out the availability of the Internet connection in the OS and then write this information to the ModbusTCP server. You can create a ModbusTCP server directly in the OS as a separate program or define it in Mervis.

The subsequent logic for switching the relay on/off is already simple.

Hello,

Unfortunately, so far we only have Neuron S103 with RPi4. This is due to higher cooling requirements and due to the different layout of connectors on RPi4.

The difference in communication speed between the variant in one box and the variant with Extension is not so important for most applications and it always depends on the optimization (number of read registers, reading period, etc.).

In general, you can assume that the speed for internal communication is 115200 bps (and higher) and the communication speed via RS485 is according to the settings, but 19200 bps is used by default due to the excellent ratio between speed and stability.

Hello,

We always (even for Unipi 1.1) recommend using a secondary external relay and using the relay on the unit only as a signal relay.

All available technical parameters for relays on Unipi 1.1 can be found in this article, for Unipi Neuron in this article and for Unipi Extensions in this article.

It is better to deal with the details of the electrical installation with an installation or inspection technician according to the legislation of your country.

Hello,

The I2C port is permanently connected to 5V and cannot be changed.
For the UART port, it is possible to change between 5V and 3.3V using a jumper (JP6).

Hello,

The production of Unipi Axon units was discontinued. The Axon line was replaced by the next generation named Unipi Patron.

Hello @L-E-F

You must create an hmi template for the function block, or for the program. Then insert "Pop-up" in the hmi template for the local web server or SCADA, where a function block, or program can be selected as a variable. Then just select the desired small template (you can have more than one ready for one block, or program).

See the attached screenshots for examples.

Hi @L-E-F

The alarm status on HMI is changed automatically according to block BD56.

1. In the default quiet state, nothing can be affected.
2. If an alarm is reported, it can be acknowledged.
3. After the alarm ends, it can be reset in the memory to the state in point 1.

The solution to your second query is simple: For a flashing state, use a GIF image as the mapped state.

Hello @emomiilol

What software do you use on the unit?
This is probably a delay caused by the software and conversion of values in combination with communication with the chip on the Unipi board. In addition, both delay factors are manifested twice:

input signal -> communication -> conversion -> program -> conversion -> communication -> output signal

Hi,

License request code can be used only once to obtain a license. If you use the request code for an account to which you later lose access, the license cannot be renewed and you must purchase a new license request to generate a new license. We therefore recommend using request codes only on the main account in the Unipi portal.

(more about the license request: https://kb.unipi.technology/en:sw:01-mervis:getting-mervis-licence-hidden)

Have a nice day
Regards
