Description

The Synchronized Analog In (AIn) functionality of the OPAL-RT Board driver provides the simulation with synchronized 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 synchronization source is a PWM signal obtained from the digital output channels of the OP5354 or OP5360-2 modules installed in the simulator. In the case of the OP4200 chassis, the OP5360-2 used is incorporated into the I/O cassette with ID OP4260-1.

Once the driver has parsed the bitstream configuration file, the user can see the location of the synchronized 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. The maximum number of analog input channels is limited by the hardware configuration of the simulator in use.

Usage

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

Slot Configuration

PWM group

All the channel groups containing channels that output PWM signals that may be used to synchronize analog input signals. Each channel group contains 8 channels.

PWM source

Channel providing the PWM signal. All analog input channels located in this slot are synchronized by the PWM signal coming from this channel.

PWM trigger type

Time in the PWM period that analog input acquisition takes place.

The Beginning option implies that analog input acquisition happens at the beginning of the PWM period,
Middle implies the middle of the PWM period and
Both implies the beginning and middle of the period.

Channel Group Configuration

Enable

Checking this box enables the acquisition of analog data for the channels in the group once the simulation has started.

Clicking Enable also adds the group of 8 channels as connectable in the sensor view of Hypersim. If the user wishes to display the analog data received in the model, connections must be made between points in the model (in the form of sensors) and the analog input connectable points.

Signals Configuration

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