Interrupt mode

Use the drop-down list in this field in order to select the interrupt mode of the card.

Here, you decide whether the card generates the interrupt for other iba PCI card installed (interrupt master) or receives an interrupt, i. e. working as interrupt slave. This is the interrupt which synchronizes the iba PCI/PCIe cards over the flat ribbon cable.

Interrupt master here means synchronization master.

• • Master mode internal This mode may be set for only one card, no matter if internal or external. Select this mode if the card should generate the interrupt for all other iba PCI/PCIe cards.

  • Master mode external This mode may be set for only one card, no matter if internal or external. Select this mode if the ibaPDA system is to be synchronized from an external source, such ibaBM-SLM. This function is required, among others, for bus-synchronous measurements using the SIMOLINK Monitor (ibaBM-SLM). The PC is then synchronized with the input data stream on channel 0 of the relevant board. The recorder feed stops if no data is received.

  • Slave mode This mode must be set for all the other boards besides the master board.

"In use" selection box

If this option is disabled, ibaPDA ignores the corresponding board. This is, for example, necessary if ibaPDA and ibaLogic are active in a hybrid configuration on the same computer, with each program requiring its own board. One card can only be used by one application at a time.

"Enable watchdog" checkbox

The board watchdog can be enabled for the purpose of monitoring the proper operation of ibaPDA by another system. If the watchdog is enabled, the board will generate an alarm message in case the acquisition is not running for more than 2 seconds. The alarm message can only be used by the FO output channel (I/O Manager: "Alarms"). Therefore, an extension module ibaFOB-4o or an ibaFOB-io-D card is required. In case of an alarm, all output values will be set to 0 (zero) in the alarm message.

The alarm is also set during the booting of the computer. If an alarm occurs, then all red LEDs light up on the FO inputs. The LED for the debug on the card then also lights up red.
