2 possible scenarios/monitoring options:

1st scenario. We are going to acquire a new machine: what specifications do we need to know about the new machine in order to monitor it? We can follow the following steps:

    1. Inform the machine manufacturer that you are using the Industry 4.0 edinn platform and that this system needs to read, in real time, and through the OPC standard, all the data and variables of the machine.
    2. If the manufacturer is concerned about the possibility that the edinn platform can write or change some parameters of the machine, we must specify that the edinn platform, unless it is developed specifically, only uses read mode. If still the manufacturer remains concerned, there is the possibility of creating a copy of the data in a memory space dedicated to edinn, so that the manufacturer's data would always be kept without access and without risk of change of any critical data.
    3. Inform the manufacturer that it is necessary to access the machine information using the OPC DA standard.

    1. The manufacturer must provide the OPC Server software for reading the machine data.
    2. Inform the manufacturer that you need the map or complete list of items within the PLC, with its name OPC, type, size and any other particularity that must be configured for reading from the edinn platform. Therefore, in this option, you must receive from the manufacturer, an installable OPC Server software (check the conditions of the license) and the map or complete list of items within the PLC (check that the list is self explanatory).

2nd scenario. We already have the machine in our facilities: how do we monitor it? There are mainly 4 possible options:

    1. Contact the machine manufacturer and follow the steps of the previous option (A). If it is not possible, then let's try the following options:
    2. Find out the PLC brand (if we do not have eBOX) of the machine from which we want to read the data, and find, install and evaluate (some providers offer a free evaluation period) an OPC Server that is able to read the PLC data.
    3. Connect the sensors and signals available on the machine to an edinn eBOX and continue with this step of this tutorial.
    4. Install new sensors on your machine and connect them to an edinn eBOX and continue with this step of this tutorial.
