Display panel has built in functions, diagnostics

A 24-character text messaging feature is built in to the new Logo! TD text display panel from Siemens, a unit designed for migrating from hardwired to programmable control.

Atlanta –A text ticker feature that can scroll up to a 24-character text message horizontally across the screen is one of the features of the new Logo! TD text display panel from Siemens Energy & Automation. Designed to be an affordable HMI (human machine interface) for equipment builders and their customers even on simple relay control systems, the panel has other built-in operator functions and customized diagnostic messages.  

The unit is designed for migrating a basic hardwired control design (pushbutton/pilot devices, rotary timers, counters, and cube relays) to a programmable controller. In most cases, only a programmable relay with a simple interface is needed for operators to adjust settings and view status.

The text display is a backlit LCD with a 128 x 64 pixel resolution capable of displaying four lines of text with up to 12 characters per line. It includes a built-in horizontal and vertical bar graph display feature, which can be configured to represent any numeric value, including an attached tank level sensor, flow rate, time or cycles. The unit also includes six buttons for screen navigation and data entry, along with four configurable user function buttons. The text display is designed in an IP65 case rated for NEMA 4/4X indoor wash down environments and is certified with industry standard agency approvals including cUL US, Factory Mutual Class 1 Div. 2, and C-Tick.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
