LogicPool (DIO)
This module supports several hardware expansions cards or submodules, no all functionalities are supported for all submodules.
Models
There is only one model for this module.
Supported hardware
SU700, SU701, SU703, SU704, SU706, SU707
Register Map
Module Address: 'T' or Ox54
Read register
Register Address | Name | Data |

1 | STATE_IN | Bit 7..0: input value |
Write register
Register Address | Name | Data |
---|---|---|

LabVIEW Vi
Digital Input/Output.
Support: SU700, SU701, SU703, SU704, SU706, SU707
According to hardware this supports either TTL,, TTL_coax, NIM or DIFFERENTIAL I/Os.
Each connector can be used as either an output (DO) or input (DI) or both.
If used as an input, terminal DO (driving output) must not be connected, as this enables the output driver and would override any input signals.
Please obey termination rules as defined for the specific used hardware!
The meaning of almost inputs and outputs of this Vi depends on the input "Function". The global inputs and outputs does not depend on the "function" input.
Glogal Inputs
DIO#: number of digital input/output to be accesed (1..255).
USB In: Handle to the LogicBox (create by open.vi), if not connected will take a global. parameter, this only works with one LogicBox at a time.
error in: error handling input
Global Outputs
USB out: Handle to the LogicBox.
error out: error handling output
Functions
Connect: connects all in/outputs and sets all parameters Inputs: "Mode": select the DIO standar. "DO" : set the signal number which will drive the output, this signal can be set or clear manually using the module "B_S.vi" (Bool to Signal). "DI" : get the signal number of which drives this input.
Set DO: set the signal number which will drive the output, this signal can be set or clear manually using the module "B_S.vi" (Bool to Signal). input: "DO" : signal number or value.
Get DI: return the logic value of this input. input: "DI": Logic value of this input.
Write Mode: Set the mode of the DIO. input: "Mode" : TTL/LVDS TTL 50 Ohm NIM Open NIM 50 Ohm
Example VIs
SU_DIO_Test.vi
or for a specific extension board:
SU700 -> SU700_TTLIO_Test.vi
SU707 -> SU707_Test.vi
