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
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
