Description

This block implements a signal mapping and rescaling interface to control analog output channels according to signals originating from the RT-XSG (FPGA) or RT-LAB (CPU) model. The signal mapping as well as the gain, offset, min and max are configured from the RT-LAB model or the Schematic Editor.

This block is capable to map from up to eight serial input in the OPAL-RT FLWS Protocol format to 32 analog output channels.

Inputs

Sync: This input must be a Bool or UFix1_0 signal. It should be a pulse train whose period is equal to the sample time requested for the Analog Output channels. Refer to the Hardware documentation for the minimum sampling time of the interface.

DataIn: This input should be connected to the solver's Data In configuration port.

DataInSof: This input should be connected to the solver's Data In configuration start of frame port.

LoadIn: This input should be connected to the solver's Load In configuration port.

LoadInSof: This input should be connected to the solver's Load In configuration start of frame port.

Model Signal Serial {1..8}: These inputs are providing the FPGA signals that could be mapped to the analog output channels. They have to follow the OPAL-RT FLWS Protocol. Inner data size is 32 bits (i.e XFloat8_24), any additional bit would be discarded. Each input can transport a maximum of 128 channels. As an example, this signal could be provided by eHS solver. (Gen4 onwards).

Outputs

Configured: This output returns the state of the AOMR, whether it is configured or not. If the block is configured by receiving Data on it's Load In signal, the Configured port outputs 1. If not, the Configured port outputs 0.

Out: This bus output contains the following signals

• Conv1: This output is conversion command that should be connected to the first Analog Output I/O interface.
• ch{0..15}: These outputs are the 16 mapped and rescaled channels that should be connected to the first Analog Output I/O interface. The output format is Fix16_11.
• Conv2: This output is conversion command that should be connected to the second Analog Output I/O interface.
• ch{16..31}: These outputs are the 16 mapped and rescaled channels that should be connected to the second Analog Output I/O interface. The output format is Fix16_11.

Characteristics and limitations

The use of this block is limited to analog output interfaces that accept the Fix16_11 fixed-point format for their inputs. And be aware AOMR block ID is no longer used in this block.
