UDP driver
This driver allows the communication between Simumatik and a generic UDP server.
Parameters
Aside from the common parameters described in the communication_driver docs, this driver includes:
- ip: IP address of the controller that want to connect to. Default = '127.0.0.1'
- port: Port number for the socket connection. Default = 8400
- polling: Polling interval in s to detect connection loss. Default = 1
- max_size: Max telegram size (bytes). Default = 1024
Setup data
The setup data will give values to the parameters required and will specify the I/O variables info.
{
"parameters": {
"ip": "127.0.0.1",
"port": 8400,
"polling": 1,
"max_size": 1024,
},
"variables": {
"inputs": {
"datatype": "byte",
"size": 1,
"operation": "write"
},
"outputs": {
"datatype": "byte",

}
}
Note
The setup_params in the generic PLC components for udp_driver will need the following format:
{"ip": "127.0.0.1", "port": 8400, "polling": 1, "max_size": 1024}
