TCweb
Tidal's New Internet-Enabled Thermocouple Monitoring System
Includes
Free Data Logger and DDE/OPC Server Application
Tidal Engineering, a leader in the design and development of embedded hardware and software for test and measurement and data acquisition applications, released the TCweb, a 16-channel thermocouple monitoring system. Among the most flexible and functional temperature acquisition instruments available, the TCweb connects to the Internet via its built-in 10BaseT Ethernet communication port or optional 56K fax modem. It is therefore configurable to automatically send e-mail reports, and alarm messages, as well as create and serve HTML report pages to any browser with a built-in Web server. By employing the built-in modem, reports and alarms may be transmitted to fax machines. In addition to offering the power to acquire, analyze, and rapidly furnish precise data, up to 16 units may be connected in a master/slave RS-485 daisy chain arrangement allowing 256 sensors to be monitored on a single Web server.
As temperature limits, thermocouple type and alarms may be set for each individual channel to facilitate unequalled versatility in the configuration of the instrument, the TCweb is ideal for use in a broad range of industries. It is appropriate for such applications as environmental chamber monitoring and validation, drug and food storage monitoring, heat treatment monitoring, and air conditioning and central heating product testing. The unit also is designed for use in automotive R&D testing, domestic and commercial refrigeration, cookers, stoves, and heater product tests.
Tidal’s monitor supports J, E, K, R, S, T, B, N, and C-type thermocouples, and boasts a display resolution of 0.1oC. Temperature measurements can be made up to 16 times per second with values reported in either Fahrenheit or Celsius. The TCweb incorporates built-in cold junction compensation and provides two digital-to-analog output channels to transmit two analog voltages for charting. In addition, a Form C alarm relay can be programmed to operate under specified conditions to energize an audible or visual annunciator. Further specifications include an operating temperature range of 32o to 140oF, and a power requirement of 3.5 W at 9 to 28 VDC. Measuring only 7.000” (L) x 5.000” (W) x 1.625” (H), it features a backlit LCD, and may be ordered with up to 8 MB non-volatile flash memory for data logging.
TCweb Data Logger
The TCweb Data Logger is a free PC based data logging and reporting application used in conjunction with
the TCweb. It is designed to connect to multiple TCwebs over
TCP/IP and capture data from their thermocouple monitors and present
that data in various forms for graphing, data analysis and control.
Additionally, the TCweb Data Logger functions as
both a DDE (Dynamic Data Exchange) server and an OPC server which makes it compatible with a large number of industrial HMI/MMI applications including Wonderware™.
An unlimited number of sensors can be DDE and OPC enabled and read from external applications.
The TCWeb Data Logger can operate in a
both a free limited mode and a full featured mode. The software is
available for download from the downloads section at the bottom of this
page. To enable the full featured mode contact Tidal Engineering to
purchase a USB or parallel port key. The capabilities of each mode are
listed in the table below. Version upgrades are posted to the website
periodically and are free to all users.

Network administrators may require the MAC address of an embedded device to administrate the network. One way to determine the MAC address of your
TCweb master unit is to use the "arp" command available on Windows PCs. This application note describes how to use the "arp" command to determine the MAC address of you
TCweb.
