Modbus Master
Basic Modbus addresses are split into 4 categories, i.e. Output Coil for Boolean output, Status Input for Boolean input, Holding Register for Integer output, and lastly Input register for Integer input. They have prefixes of 0x, 1x, 4x and 3x respectively, and they are simplified into single number 0, 1, 4 & 3 and can be entered into the `addresEx` column for specifying the address type.
stationId
Station ID is the node address of the Modbus device in the network.
 
timeout
Practical timeout value should be less than 3s unless in a very slow network.

offset
The `offset` parameter is meant to adjust the data addresses to ensure the index is not misaligned between master and slave. To confirm if the data address is correctly aligned, just try to poll one known value of any address that's not at the start, i.e. Avoid 4x0000 or 4x0001 to avoid comm error. The possible offset values are either -1, 0 or 1.

dataFormat
The 32bit data types like real32, int32, uint32 may have different data bytes order, you may control the mapping by entering ABCD or CDAB, or otherwise in a reversed manner DCBA or BADC.

OPC UA Client
OPC UA driver should be straightforward in configuration, as the `subscription` is default to `true` so no manual polling is needed for `trigger`,  the main parameter is the URL that connects to the OPC UA Server. For instance:
"url": "opc.tcp://127.0.0.1:49320"

Once you can see that OPC server is connected, you should also notice that a message will be prompted that a new "*.all.csv" will be created. Please wait patiently until another completion message is prompted before you proceed to stop the driver.

Open the auto generated CSV file and you may copy and paste the interested tags into your working CSV.

NOTE:
1.	The *.all.csv will not be generated again until the old one is removed.
2.	If the OPC Server is having bad data due to offline devices, then the correct data type cannot be fetched, although it won't affect the polling later.
3.	The `trigger` parameter should be empty in most scenarios, unless otherwise you want to perform additional manual polling in a specific interval.

Profinet
Profinet offers a param `model` to differentiate between protocols used by different models of Siemens PLC.
Below is are the available options for `model`:
-	S7-1200
-	S7-300
-	S7-400
-	S7-1500
-	S7-200Smart
-	S7-200

For S7-300 and S7-400, you will need to configure the setting for `slot` and `rack`. For S7-200, you need to configure `locaTSAP` and `destTSAP` accordingly.

Below is the sample json configuration for Task section:
"task": [
  {
      "url": "127.0.0.1:102",
      "model": "S7-200",
      "localTSAP": 0,
      "destTSAP": 0,
      "rack": 0,
      "slot": 0,
      "timeout": 3000,
      "trigger": [1000],
      "id": "plc1",
      "data": [
          {
              "$csv": "dxprofinet.csv"
          }
      ]
  }
]

EthernetIP
DX Allen Bradley EthernetIP module allows you to configure and connect to Allen Bradley PLCs  1756 & 1769, 1747 and Micro800 series.

Below are the parameters for setting up the connection to the desired Allen Bradley PLC.

deviceID
Required, you may enter the slot number.

deviceType
You may enter the type of the device. Supported options are 1756/1769, 1747, micro800, df1serial.

url
You may enter the url where the Allen Bradley PLC is connected.

trigger
You may enter the timer for the read / write operation to trigger.

name
You may enter the tag name associated with the Allen Bradley PLC.

address
You may enter the address of the memory that stored the data. Error will be returned when writing to or reading from non-existent addresses.

dataType
You may enter the data type of the data associated with the tag. Supported data types include bool / boolean, byte, double, float, int16 / short, uint16 / ushort, int32 / int, uint32 / uint, int64 / long, uint64 / ulong and string.

length
You may enter the length of the string. For other data types, this parameter is not required and will automatically set as 0.

Example: configuration file (.json)

{
  "id": "dx",
  "task": [
	{
	   "enable": true,
	   "id": "device01",
	   "deviceID": 1,
	   "deviceType": "", //micro800; 1756/1769; 1747; df1serial
   "url": "127.0.0.1",
	   "trigger": [ "1000" ],
   "readOnly": false,
	   "data": [
		{ "$csv": "tag.csv" }
	   ]
    }
}
