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:

Parameter	Default Value	Description
ip	127.0.0.1	The Beckhoff TwinCAT route to the PLC.
port	8400	Port number for the socket connection.
polling	1	Polling interval in s to detect connection loss.
max_size	1024	Max telegram size (bytes).

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",
      "size": 2,
      "operation": "read"
    }
  }
}

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 }
