Description
The ML605EX1 Digital In block is used to return 0/1 data values obtained from the digital input channels of an OP5353 carrier connected to an ML605 board.
The data values are transferred from the ML605 bitstream to the RT-LAB model through one DataOut port of the bitstream, via the PCIe bus of the target computer.
Each ML605 bitstream using Digital Input channels comes with a configuration file which lists the Data port number and the corresponding OP525x location in the system. The configuration file name is the same as the bitstream file name entered in the OpCtrl ML605EX1 block, with the extension .conf instead of .bin.
This configuration file uses three parameters to describe the location of the OP525x channels:
- the Slot number (in the range 1 to 4) is the slot of the backplane connected to the ML605 in which the OP5251 is installed,
- the Section A or B is a subset of 32 lines of the OP525x carrier. For example, with the 32 In/32Out OP5251 carriers, section A refers to the 32 input lines and section B to the 32 output lines,
- the Sub-Section, 1 to 4, is a subset of 8 channels connected to one DataOut port: subset 1 represents the 8 first channels of one section of the OP525x, subset 2 represents the 8 next channels, etc.
The user must refer to the configuration file (opened with any text editor) for selecting the DataOut port number for the desired Digital Input channels. The ML605EX1 Digital In block then parses the configuration file and displays the Slot, Section and Sub-section values corresponding to the DataOut port number in the 'Slot info' parameter.
The maximum number of Digital Input channels controlled by one ML605EX1 Digital In is limited by the size of the subset of channels in one sub-section. This number can vary between 1 and 32 and is usually set to 8.
Parameters
| ControllerName | Bind this block to an OpCtrl ML605EX1 block by entering the same 'Controller Name' as specified in the OpCtrl ML605EX1 block The OpCtrl ML605EX1 block controls initialization of the settings of one specific ML605 card in the system. |
|---|---|
| DataOut port number | Enter the number of the DataOut port to be controlled by this block, in the range [1:32]. |
| Slot info | This non-editable parameter displays the physical location of the digital input channels related to the selected DataOut port, as obtained from the parsing of the configuration file. |
| Maximum number of DIn channels controlled by this block | This non-editable parameter displays the number of channels in one sub-section listed in the configuration file. |
| Number of DIn channels | Enter the number of channels for which data values will be returned at each calculation step. This number must be less than or equal to the value of the 'Maximum number of DIn channels' parameter. The data transfer mechanism between RT-LAB and the ML605 does not allow the selection of individual channels in the sub-section of channels. The data returned by the block will thus correspond to the N first channels of the sub-section, where N is the value of the 'Number of DIn channels' parameter. |
| Sample Time (s) | This parameter allows the user to specify the block sample time in seconds. The default value is 0, which specifies a continuous sample time (note that the sample time is borrowed from the separated subsystem) while -1 specifies an inherited sample time. A functionality block and its associated controller block must execute at the same sample time. |
Inputs
This block has no inputs.
Outputs
This block has two outputs.
Vals: This output returns the 0/1 values of the subset of channels selected.
Status: This output returns the following values:
| Value | Description |
|---|---|
| 0 | No error. |
| -1 | Block could not be matched with an OpCtrl ML605EX1 block (check the 'controller Name' value), or ML605 card initialization problem. |
| -2 | Data reception timeout. This error can be caused by model synchronization errors. |
| -3 | Data reception error : the block received less data from the ML605 card than the value specified in the 'Data outport width' parameter. Missing data were replaced by 0. |
| -4 | Data reception error : the block received more data from the ML605 card than the value specified in the 'Data outport width' parameter. Extra data were discarded. |
