This arrangement when you use Touch•PLS because it does double duty; serving makes it easy to display data from both the PLC and PLS on as a PLS interface/control as well as an operator interface to one screen. In addition, 32 registers (16 in each direction) are the PLC.

Remote selection of PLS programs may also be accomplished by a PLC. Leading- and Trailing-Edge Speed Compensation Touch•PLS features a Speed Compensation (Rate Offset) to compensate for speed variations. The Rate Offset, individually programmable for each channel, is used to advance the PLS settings as a function of the machine speed Pulse Programming Touch•PLS can be fine-tuned while your machine is running. Either or both of the ON and OFF Setpoints can be incre- mented or decremented, or a fixed dwell can be incremented or decremented, as needed.

This is not to say that µWIN translates English-language phrases into those of other languages—it only recognizes strings of ASCII characters. You can create up to 16 text strings (memory dependent) for each object— each in a differ- ent language. (Please note the more screens and words you use, the more memory you use, and the fewer sets of text strings per object you can create.) To use this feature, a user will design a screen as usual, and enter text strings, where applicable, in as many languages as desired (16 max.). You do not have to design & maintain sepa- rate screens for each language. All your operator has to do is go to the language selection screen and select the language you've already programmed into the Touch•PLS. All screens will then display their messages in the language selected. 800-TEC-ENGR Programmable Limit Switches D-11 www.avg.net SECTION D TOUCH•PLS SPECIFICATIONS Power Requirements: INPUTS/OUTPUTS: 5" Color and 6" Models: 24 VDC @ 18 W Electrical Specifications: 8" Color Model: 24 VDC, 24 W I/O Power Input: 20 to 30 VDC @ 100 mA + user's loads 9"Amber EL Model: 115/230 VAC <40 VA or 24 VDC <40 VA 10" Color Model: 120 VAC ±10%, 50-60 Hz, @ 1 A or N-Channel Sinking I/O 24 VDC @ 1.25 A Output Logic Levels: Operating Temperature: Logic TRUE: MOSFET ON, 0.2 V Max. @ 100 mA 5" Models: 32 to 122 °F (0 to 50 °C) Logic FALSE: MOSFET OFF, 0.05 mA leakage @ 30 V 6" and 8" Models: 32 to 104 °F (0 to 40 °C) Max.
