Simit driver
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:
- SHM_name: Name of the shared memory. Default =
SIMITShared Memory
- big_endian: True if big endian, else little endian. Default =
False
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,}
