bom dia estou buscando informações de como realizar a terefa de consumo de uma API, tenho S7-1200 e preciso buscar informações no servidor e depois enviar novamente informações, o PLC vai navegar em um banco de dados de carregamento e vai selecionar um pacote de informações e vai retornar a resposta no mesmo local do banco de dados. Eu até tentei usar o Banco de dado SQL mais TI não liberou.

Good morning, I'm looking for information on how to perform the task of consuming an API, I have an S7-1200 and I need to search for information on the server and then send information again, the PLC will browse a loading database and select an information package and will return the response in the same location in the database. I even tried to use the SQL Database but IT didn't release it.

1.The automation requests the DOCA and the LOAD number that will start the conference.

2.Automation increments a read sequential identifier (IDS).

3. Automation captures the information contained in the QRCode of the merchandise box that was placed on the conveyor belt.

4. The automation, through a rest api (web service), sends a json to Harpia WMS

{

"IDS": number,

"DOCK": sequence,

"LOAD": number,

"QRCODE": string

}

The information is processed in Harpia WMS and will be returned as json in the following format

{

"STATUS": string,

"MSG": string

}

The following values are for STATUS and MSG respectively

0 - MERCHANDISE EXCEEDS QUANTITY REQUESTED;

1 - CONTINUOUS READING;

2 - FINISHED LOAD;

RN1.If "0" the conveyor belt must stop, issue an alert and make available the information sent through the MSG in the case of the example above it would be "MERCHANCE EXCEEDS THE QUANTITY REQUESTED";

RN2. If "1" the treadmill should continue normally

RN3.If "2" the treadmill must stop, issue an alert and make the information sent through the MSG available, which in the case of the example above would be "LOAD FINISHED"

RN4.If the Harpia WMS response is "0", the conveyor belt will be stopped, the operator must remove the box from the conveyor belt and, through a manual action, allow the boxes to continue reading.
