Driver that can be used to connect with SIMIT using shared memory.

Parameters

Aside from the common parameters described in the communication_driver docs, this driver includes:

Parameter	Default Value	Description
SHM_name	SIMITShared Memory	Name of the shared memory.
big_endian	False	True if big endian, else little endian.

Setup data

The setup data will give values to the parameters required and will specify the I/O variables info.

{
  "parameters": {
    "SHM_name": "SIMITShared Memory",
    "big_endian": true
  },
  "variables": {
    "MW4": {
      "datatype": "word",
      "size": 1,
      "operation": "write"
    },
    "MW0": {
      "datatype": "word",
      "size": 2,
      "operation": "read"
    }
  }
}

note

The setup_params in the generic PLC components for simit will need the following format:

{ "SHM_name": "SIMITShared Memory", "big_endian": true }
