Description

The OP7160EX1 Digital In block is used to return 0/1 data values obtained from the digital input channels of OP5353 module(16 Digital In conditioning module) installed on OP7220 Compact Universal Carrier. OP7220 Universal Carrier is connected to OP7160 board via OP7000 I/O box..

The data values are transferred from the OP7160 bitstream to the RT-LAB model through one DataOut port of the bitstream, via the PCIe bus of the target computer.

Each OP7160 bitstream using Digital Input channels comes with a configuration file which lists the Data port number and the corresponding OP5353 location in the system. The configuration file name is the same as the bitstream file name entered in the OpCtrl OP7160EX1 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 16) is the slot of OP7000 I/O box where OP7220 Compact Universal Carrier is installed,
the Side (A/B) is obsolete for the OP7000 I/O box.- the Sub-Section, 1 to 2, is a subset of 8 channels connected to one DataOut port: subset 1 represents the 8 first channels of one section of the OP5353, 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 OP7160EX1 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 OP7160EX1 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

Controller Name	Bind this block to an OpCtrl OP7160EX1 block by entering the same 'Controller Name' as specified in the OpCtrl OP7160EX1 block The OpCtrl OP7160EX1 block controls initialization of the settings of one specific OP7160 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 OP7160 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 OP7160EX1 block (check the 'controller Name' value), or OP7160 card initialization problem.
-2	Data reception timeout. This error can be caused by model synchronization errors.
-3	Data reception error: the block received fewer data from the OP7160 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 OP7160 card than the value specified in the 'Data outport width' parameter. Extra data were discarded.
