Frequently asked questions about iDaq

 
 

What is the difference between iDaq Device Manager and iDaq Dock?

iDaq Device Manager is the application that acquires data from hardware, like DAQmx boards, CompactDAQ, ModBus, Siemens S7 PLC, Ethernet IP devices.
iDaq Dock is a container of addons. It allows you to launch addons and to arrange them in projects. An addon is an application that processes, stores and visualizes signals and any other type of data acquires with iDaq Device Manager.

What is the difference among Driver, Extension and addon?

They are three different categories of functionalities associated to iDaq Device Manager and iDaq Dock.
Drivers communicates with hardware (like DAQmx boards) and acquires data from them. They are distributed as iDaq-Driver files and must be installed in iDaq Device Manager.
Extensions are additional functionality for processing of data acquired by iDaq drivers. Examples of iDaq extensions are virtual channels and WPU (waveform processing units).
Addons are applications that processes, stores and visualizes signals and any other type of data acquired with iDaq Device Manager.

How many channels does iDaq support?

iDaq supports unlimited channels.

I want to activate Easy Datalogger for iDaq. Do I need two licenses for the addon and standalone version?

No, once an addon is activated, both versions (standalone and integrated addon) are activated.

Does iDaq Device Manager support DAQmx devices only?

No, iDaq Device Manager supports different types of hardware: DAQmx, Siemens PLC, Ethernet/IP devices, ModBus devices, XNET-CAN devices, etc.

Can I acquire data from an XNET-CAN device?

Yes, using XNET-CAN driver for iDaq Device Manager, you can acquire data from CAN bus devices in the same way as CompactDAQ modules or any other device connected to iDaq Device Manager.

Can I use iDaq Device Manager and iDaq Dock on different PCs?

Yes, iDaq Device Manager and iDaq Dock can run on different PCs. The only requirement is that both the PCs are connected to the same network.

I have connected a CompactDAQ with four modules. When I add all the four modules to the active device list, one of these devices generates an error. Why?

Due to a limitation of DAQ-mx devices, no more than three modules of the same CompactDAQ Chassis can be used simultaneously. To overcome this limitation, use cDAQChassis Driver, distributed with iDaq Device Manager. With this iDaq component, you can aggregate more CompactDAQ modules in a unique device and more than three modules of the same chassis can be used simultaneously.

Is there a way to save and load device and channel configuration to switch configuration quickly?

Yes, snapshot feature allows to save and store device and channel configuration in ease. To access to the snapshot feature, click on Backup Configuration Button in the main interface of iDaq Device Manager.

Is there a way to arrange the multi channels strip charts in separate axis?

No, you cannot change display mode to stack charts, due to a limitation of LabVIEW that doesn’t allow changing that property at run-time. In any case recorded signals are aligned and you can load recorded data with LabVIEW and display stacked charts.

If I use LabVIEW SDK addon to display the strip chart as I want, does iDaq Device Manager record the channels or shall I record it in LabVIEW?

You can create a simple standalone application according to your needs. In this case, you can create a standalone application that record data in your favorite data format and display stacked charts.

How can I monitor data of my real-time controller with iDaq?

You can use CompactRIO Driver for iDaq that allows the acquisition of real-time data from CompactRIO systems. This high-performance driver includes a SDK that let you customize your real-time applications in a few clicks.
