Description

OpPickering_41_752_BattSimulator block	Designed to program Pickering's PXI-41-752 6-channel battery simulator module.
41-752 board	Single slot PXI module to be placed in an appropriate PXI chassis (e.g. Pickering PXI 40-922). RT-Lab block running in the target communicates with the module through a regular PCIe link, therefore a PXI-PCI interface is required (e.g. Pickering PXI 41-924 kit).
41-752 module	Contains 6 battery channels which can be programmed independently. At this end, every input of the RT-Lab block is a 6-value vector addressing each channel of the battery simulator.
Battery simulator	Can supply maximum 7V and 300mA per channel and sink up to 100mA per channel. Cells can be chained together in order to increase the final output.

Parameters

Module ID (Slot ID)	Index of the board on target's PCI bus; it can be found using the command lspci.
Bus ID	Logical bus ID tied to board on target's PCI bus; it can be found using the command lspci.

Example with 4 boards available:

08:0b.0 Class ff00: PLX Technology, Inc. PCI9030 32-bit 33MHz PCI <-> IOBus Bridge
08:0c.0 Class ff00: PLX Technology, Inc. PCI9030 32-bit 33MHz PCI <-> IOBus Bridge
08:0d.0 Class ff00: PLX Technology, Inc. PCI9030 32-bit 33MHz PCI <-> IOBus Bridge
08:0e.0 Class ff00: PLX Technology, Inc. PCI9030 32-bit 33MHz PCI <-> IOBus Bridge

When multiple cards are available, they are arranged from right to left in the PXI chassis. In the example above, the board with slot ID = 0x0b (11) is the right-most one, and Bus ID is the first number on each row, in this case 08.

Inputs

Vout	6-value input vector set the output voltage for each channel. Vector values are in volts going from 0 to 7V.
Isink	6-value input vector to set sink current for each channel. Vector values are in Amps going from 0 to 0.1A.
Cell_en	6-value input vector to enable/disable a channel of the module. Vector values are 0 for disabled and 1 for enabled.
Ex: [1 1 1 0 0 0 ]	enables the first 3 channels and disable the 3 last channels.

Outputs

InterLockSt

Reports the module interlock status. Value is set to 0 if interlock is disabled (jumper between pins 16 and 17 is missing), and 1 if enabled.

The module will not operate until interlock status is 1 (this is a hardware condition).

ModuleErr

Error reported by the module at board level.

CellErr

Error reported by the module at the channel level (vector of 6 error codes).

Note: Not all error codes apply for Pickering 41-752 Battery simulator board.

Characteristics and Limitations

Multiple blocks can be added in an OPAL-RT model as long as each one drives a different module (unique slot ID).

For further information on the PXI 41-752 module itself, please read the following documentation given with your system from Pickering: 41-752D.pdf (datasheet), 41-752M.pdf (user manual).

Note: The channel is equivalent to a cell of a real battery.

Installation Requirements

This block requires Pickering's libpilpxi32 shared library (must be found in the libraries path).
