Controls the relay for channel n. When the input value is '1', the relay is energized, '0' puts it back to its idle state. The schematics in the section I/O pin mapping show the relays in their idle state for each module type. The number of these ports is dependent on the channel count, which is specified by the 'Channels vector' parameter. If the option "Combine all channels in one vector port" is checked, there is only one input port named "All Ch". It takes a boolean vector with a width defined by the specified number of channels to be used.

Monitors the current state of each channel's relay. When the output value is '1', the relay is energized, '0' means that the relay is in its idle state. The schematics in the section I/O pin mapping show the relays in their idle state for each module type. The port is only shown when the "Show output ports" option in the mask is checked. The number of these ports is dependent on the channel count, which is specified by the 'Channels vector' parameter. If the option "Combine all channels in one vector port" is checked, there is only one output port named "All Ch". It takes a boolean vector with a width defined by the specified number of channels to be used.

If your target machine only contains one I/O module, leave the default value (1). If more than one I/O module of this type is present, select a unique number (1-255) for each of your modules.

Select the specific type of I/O module this driver block is being used with.

This parameter defines which channels are used and how they are ordered on the driver block. The parameter takes a row vector with values from 1 to the number of channels supported by the selected module.

Defines the initial state of the relays. Valid values are '1': relay energized or '0': idle position. A scalar value or a vector of the same length as the "Channel vector" can be entered. If a scalar value is specified, this value is applied to all channels. If a vector is specified, the values are mapped to the channels as defined in "Channel vector". The relays are set to their initial states between the time the model is downloaded and the time it is started. Before the model is downloaded, all relays are in their idle state (see I/O pin mapping).

The reset vector controls the behavior of the relays at model termination. A scalar value or a vector of the same length as the "Channel vector" can be entered. If a scalar value is specified, this value is applied to all relays. If a vector is specified, the values are mapped to the channels as defined in "Channel vector". If a value of '1' is entered, the corresponding relay will be reset to the state specified in the initial value vector. If a value of '0' is entered, the relay retains the last state set during model execution.

When checked, there is only one input port named "All Ch". It takes a boolean vector with a width defined by the specified number of channels to be used. This also applies to the output port, if enabled.

Enables or disables the output ports.

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.

There are two approaches for mapping this block to a specific I/O module installed in your target machine. All modules of the same type must be configured using the same method.
