OpScramnet Controller
- Sylvain Ménard
Block

Description
This block is used to define the settings of a PCI or PXI SCRAMNet+ SC150e device. All OpScramnet Read and Write blocks refer to this controller using the unique Controller and node ID which can range from 1 to 255.
General Parameters
| Controller and Node ID | Unique ID that will be used to identify the node on the network and by the Write and Read blocks. The value must be ranging from 1 to 255. |
|---|---|
| PCI/PXI Index | index of the device on the PCI or PXI bus. |
| Memory byte ordering | Specifies whether the compatibility with the physical device will be little-endian or Big-endian. The x86 architecture is little-endian. For example, the hexadecimal number 0x12345678 is stored in memory using little-endian as: |
Address | Content |
|---|---|
0 | 0x78 |
1 | 0x56 |
2 | 0x34 |
3 | 0x12 |
A Big-endian format would store the data in the following order:
Address | Content |
|---|---|
0 | 0x12 |
1 | 0x34 |
2 | 0x56 |
3 | 0x78 |
Sample time: The sample period in second. Use 0 for continuous and -1 for inherited. This is the sample time parameter commonly encountered in the Simulink block library.
Inputs
This block has no inputs.
Outputs
Status: This output is available only if the Use status output parameter is checked. This output is a 16 signals wide vector reporting the contents of the CSR1 status register of the SCRAMNet+ board. The signification of each signal is described below (refer to the SCRAMNet+ documentation for more details):
| Signal Index | Name |
|---|---|
1 | Transmit FIFO full |
2 | Transmit FIFO Not Empty |
3 | Transmit FIFO 7/8 Full |
4 | Always 0 |
5 | Interrupt FIFO Full |
6 | Protocol Violation |
7 | Carrier Detect |
8 | Bad Message |
9 | Receiver Overflow |
10 | Transmit Retry |
11 | Transmit Retry Time-out |
12 | Redundant Transmit/Receive Fault |
13 | General Purpose Counter/Timer Overflow |
14 | Current Link |
15 | Interrupts Armed |
16 | Fiber Optic Bypass Not Connected |
Restarting the application may be required to clear some of the errors and resume operation.
Characteristics and Limitations
This block has no special characteristics.
| Direct Feedthrough | No |
|---|---|
| Discrete sample time | Yes |
| XHP support | No |
| Work offline | No |
