Note
Maximum limit for the number of connections is 64.
S7+ data point parameter¶
In order to collect the data of your S7+ device, you must add new data points.
The following image shows the data point parameter window:
The following table shows the parameter of the S7+ data point window:
| Parameter | Description |
|---|---|
| Datapoint type | The following datapoint types are supported: - int - long - double - boolean - string |
| Datapoint Address | The PLC connection must be available (symbolic addressing is used). |
| Type Transformation | The transformation type is the interpretation of data of the peripheral device. For the datatypes above the following transformation types are available (see also table below): - int: UINT, USINT, UDINT, SINT, INT, DINT, WORD, BYTE, DWORD - long: UINT, USINT, UDINT, ULINT, SINT, INT, DINT, LINT, WORD, BYTE, DWORD, LWORD, DATE, DATETIME, TIME, TIME_OF_DAY, LDATETIME, LTIME, LTOD, DTL, S5TIME - double: REAL, LREAL - boolean: BOOL - string: STRING, WSTRING, DATE, DATETIME, TIME, TIME_OF_DAY, LDATETIME, LTIME, LTOD, DTL, S5TIME |
| Data Acquisition Mode | The following modes are supported: - READ - WRITE - READ and WRITE |
