The block sends out read requests as long as the input port is TRUE.

Best practice is to set the block's sample time to a higher rate (like 1 ms) and trigger the Enable input port at a lower rate. This ensures low network traffic but immediate updates of the output ports once a response is received.

Data type: boolean

Outputs the current value of the requested record. The port inherits the data type and the dimensions from the Init Value parameter. The data type and dimensions do not both need to match the data type and dimensions of the record in the remote slave device, but the overall number of bytes must be equal to or greater than the size of the record. The block outputs the number of bytes received (padded by zeros), or truncates the data if it exceeds the port size. The Length output port outputs the actual number of bytes received.

Data type: Fundamental data types from boolean to double are supported as well as dimensions from scalar values to vectors.

A rising or falling edge indicates a completed read operation. Either a response was received and the Data output port was updated or the Error output port provides an error code.

If the Status output does not change, the read operation is still in progress or the block is idle.

Data type: uint32

Outputs the error code reported by the driver, the protocol stack, or the remote device (the error included in the response).

Data type: uint32

Outputs the number of data bytes received. The value will always be less than or equal to the size of the Data output port.

Data type: uint32

The index of the remote PROFINET device. Find the index in the SYCON.net project. In SYCON.net, double-click the controller node. In the navigation area, click Device Table. In the table on the right, navigate to the device whose record you want to read and locate the device index in the Index column.

The API of the module to which the record belongs. Valid values are between 0 and 0xFFFFFFFF.

The slot of the module to which the record belongs. Valid values are between 0 and 0xFFFF.

The subslot of the submodule to which the record belongs. Valid values are between 0 and 0xFFFF.

Enter the index of the record within the respective subslot. Corresponds to the XML attribute Index of the related ParameterRecordDataItem in the GSDML file. Valid values are between 0 and 0xFFFF

The value that the Data port outputs before a read response is received. The parameter's data type and dimensions define the data type and dimensions of the Data output port and specify the length of the requested data. Fundamental data types from boolean to double are supported as well as 1D-arrays.

The Init Value corresponds to the XML attribute Data of the related ParameterRecordDataItem in the GSDML file.

The time the module should wait for a response from the remote device before allowing the next Record block to send out its request.

If selected, the block shows the Status, the Error and the Length output ports. Otherwise, the ports are hidden.

Defines the base sample time at which this driver block gets its sample hit. This parameter can also be set to -1 for inherited sample time. The units are in seconds.
