_The WebDAQ 316 intelligent logger features remote monitoring and control of real-time temperature data._ 

## **Overview** 

The WebDAQ 316 is a stand-alone, temperature logger designed for remote monitoring and control. All the intelligence is built into the WebDAQ, eliminating the need for a PC or additional software. By using the embedded WebDAQ web server, users can easily configure simple or sophisticated applications, log temperature data, update digital outputs and/or send notifications based on alarm conditions, and view real-time data from any location and any device with a web browser. 

The WebDAQ 316 provides 16 isolated thermocouple inputs, and four isolated digital bits that can be used as trigger inputs or alarm outputs. Housed in a heavyduty chassis, the WebDAQ 316 is rugged enough for industrial applications. 

- **Share folders to view files over a local network** 

- **Export data to csv, UFF, or binary for use in other applications** 

- **Alarm and event notifications with email and SMS messaging** 

- **Easy, flexible task scheduling** 

- **Configurable read/write access** 

- **No driver software to install** 

- **Built-in web server** 

- **Remote monitoring and control** 

- **WiFi support** 

## **Integrated Software and Hardware** 

The WebDAQ Series embedded OS and web server provides an all-in-one package for stand-alone data logging and alarming. Users can monitor and control their applications from anywhere with a web browser. 

## **Remote Access and Control** 

Install the WebDAQ 316 on any network and access it using any device with a web browser to remotely monitor and control all operations. Users can connect a WiFi adapter to the rear panel and communicate with the WebDAQ over a wireless network. 

## **Flexible Triggering** 

Start or stop the acquisition based on analog or digital thresholds, alarm states, or date/time values. On-demand push button triggering is also supported. 

The WebDAQ web server is optimized for both desktop and mobile use. Users can perform data acquisition tasks from phones, tablets and laptops with a single, intuitive user interface. 

## **WebDAQ Web Interface** 

An embedded web server provides a clean, intuitive interface to access all configuration and data management tasks. 

Hardware, trigger and alarm settings are contained in a single task, or “job”. Multiple “jobs” can be run in a “schedule” for more complex data logging applications. 

For example, users can create a schedule of jobs in which one job automatically runs after an alarm condition is triggered on a different job, such as when a temperature is reached or when a digital input changes. 

_Device-independent operation lets you remotely monitor and control the WebDAQ 316 from any device with a web browser._

## WebDAQ 316 Introduction 

## **Easy Setup – Powerful Capabilities** 

Jobs are the building block of WebDAQ. The ability to define different data logging jobs, or tasks, and add them to a schedule unleashes flexibility not seen in any other data logger. 

Whether you want to set up a simple logging task or a complex task, jobs and a schedule make it easy and straightforward. 

## **What is a Job?** 

The basic building block of WebDAQ, a job defines channel configuration, logging options, start and stop conditions, and alarming. 

## **What is a Schedule?** 

A schedule is a collection of jobs that gives flexibility to dynamically change data logging attributes, such as sampling rate, active channels configuration, or alarm levels. 

## **Example:** 

**Switching from static acquisition to dynamic acquisition.** 

## **1 Schedule and 2 Jobs** 

**Users can easily setup a job for a slow, static acquisition and a fast dynamic acquisition. When a trigger condition is met (i.e. over/under alarm), Job 1 (slow acquisition) ends and Job 2 (fast acquisition) begins. When the trigger condition returns to normal, job 1 can be restarted.** 

## **Clear, Concise, Data Displays** 

**WebDAQ users don’t need to rely on the small screens and difficult to navigate displays of most other loggers. With WebDAQ’s intuitive web interface, users can easily see their data and alarm conditions in real time or after the acquisition is complete.**

## WebDAQ 316 Features 

**==> picture [96 x 55] intentionally omitted <==**

## **Alarm and Event Notifications** 

Create multiple alarms using analog or digital channel sources. Configure alarms to reset and re-arm when the condition clears, or reset them remotely with your browser. View the alarm status on the web interface. 

Users can configure one or more events to record when a job is started, stopped, or triggered, or if an error condition is detected. 

Receive alarm and event notifications on one or more addresses using email and SMS messaging. 

## **Virtually Unlimited Storage** 

Store data files and configuration settings locally in internal flash memory, or save to external media or network folders. 

Users can map a network drive or FTP server as the location to log data or store files. 

Easily transfer files between WebDAQ storage locations and mapped network storage locations. 

## **Share Folders** 

Users can share a WebDAQ storage location or specific folder over a local network. 

## **Real-Time Data Display** 

View data as it is acquired or from a stored file. Users can specify a range of data to view and zoom in or out. Data is plotted on strip chart and scalar displays. 

## **Control Read and Write Access** 

Users can control who can view and modify job settings by defining a password and setting the security level for the admin account. A “share” password can be used to access a shared folder or FTP server running on the WebDAQ. 

## **Run the Schedule on Startup** 

Automatically run the schedule when the system starts up. Multiple jobs in the schedule are run consecutively. 

## **Real-Time Clock** 

A real-time clock provides an absolute time reference for timestamping data. The clock can be set to any timezone, and may be synchronized to the internet time server. 

## **Isolated Thermocouple Inputs** 

The WebDAQ 316 provides up to 16 thermocouple channels. Thermocouple inputs are isolated from ground. Overvoltage protection is provided between any two inputs. 

## **CJC and Auto Zero Support** 

Cold junction compensation (CJC) is enabled for all channels. Users can enable auto zero to compensate for offset errors. 

## **Isolated Digital I/O** 

The four isolated digital I/O lines can be used either as triggers to start or stop the acquisition or as alarm outputs. 

## **Flexible Power Requirements** 

Provide power with the 9 volt, 1.67 amp supply that ships with the device, or connect any 6 to 16 DC supply 

## **Firmware Updates** 

Device firmware is bundled with the operating system and web server in one update file. This allows the WebDAQ 316 to be updated in the field. 

## **Calibration** 

The WebDAQ 316 is factory-calibrated using a NIST-traceable calibration process. Specifications are guaranteed for one year. Return the device to the factory for recalibration.
