Description

The Analog In functionality of the OPAL-RT Board driver provides the simulation with the analog input acquisition data obtained from the analog input channels of the OP5340 modules installed in the simulator.

In the case of the OP4200 chassis, the OP5340 module is incorporated into the I/O cassette with ID OP4240-1.

The data values are transferred to the simulation through the DataOUT ports of the FPGA.

The data port numbers and the location of the analog input modules in the simulator are specified in the bitstream configuration file, which must be provided in the main section of the current board's configuration.

Once the driver has read the bitstream configuration file, the user can see the location of the analog input modules and can configure them.

The OPAL-RT Board driver can control all of the analog input modules of the simulator at the same time. Therefore, the maximum number of analog input channels is limited by the hardware configuration of the simulator in use. 

Usage

The present document describes the usage of the standard analog in functionality of the simulator. For the resolver in functionality that makes use of the analog input modules of the simulator, please see the Resolver Inputs documentation.

Once the bitstream configuration file has been parsed, the location of the analog input modules becomes visible to the user. The channels of the modules are grouped into bunches of 8. By clicking on each group of 8, the user has access to the configurable options of the group.

Channel group configuration

Signals Configuration

Channels in analog input groups do not have any parameters to configure.

Characteristics and limitations 

For the connector pin assignments, the user should refer to the carrier documentation.
The current version of the analog input functionality of the OPAL-RT Board driver has the following limitations:
