Technical support / Re:getting the 4x20 LCD to work??
« on: March 01, 2005, 10:20:54 PM »
Make sure DIP-Switch #4 is not set to ON position. If DIP-Switch #4 is ON, it will set PLC to PAUSE mode. If the PAUSE red LED is lit/ON, then the PLC is in PAUSE mode. The PAUSE red LED is located near the PLC DC power connector.

Check and make sure your PLC is NOT in PAUSE mode.

Technical support / Re:PLAYING WAV.FILE
« on: March 01, 2005, 07:32:18 AM »
I am working on a Vending Machine application in which the Tri-PLC controls a wav.file Voice Record and Playback Module.

The Tri-PLC via Voice module playback up to 64 different pre-recorded messages.

Five Tri-PLC outputs are required to playback one Voice Module message at a time out. One PLC output select Voice module playback mode. The other four PLC outputs select one out of 64 messages to be playback.

Is this simmilar to what you are trying to do?

If you need additional technical help with your project, please contact me. I am a PLC-SCADA Engineering Consultant with more than 20 years experience helping inventors turn ideas into a reality.

You must be having a simmilar problem I also experience with TRiLOGY.

You created a parallel or ORded logic and now you are trying to add/append more logic  to the left and the yellow highlighted TAB key insertion point is not allowing you to append logic.

Here is the solution to your problem: With TRiLOGY in editing mode, look at the logic elements tool bar almost on the top of the TRiLOGY window. On the rightmost end of this toolbar, there is a solid right arrow-head. If you click on this right-arrow head, it will move your yellow highlighted insertion point to the right and now you can append logic to your rung.

This bug is very annoying because the TAB key works very well for any other scenario except with parallel or ORded logic. I am going to let Leon, Triangle Research, know about this annoying TRiLOGY bug.

Please let me know if this works. If you need additional technical help with your PLC project/s, please let me know. I provide techincal support for PLC-SCADA based systems.

General Discussions / Re:Gathering Data from Manufacturing line.
« on: February 13, 2005, 08:29:28 AM »
What is the speed (RPM) and how many pulses per revolution your tachometer is going to generate?

What is the maximum Unit-Count per second?

What is the maximum cycles per second of manufacturing line?

If any of the previous frequencies is less than 100Hz, you can use regular Tri-PLC inputs triggering regular internal PLC counters and timers.

If any of the previous frequencies is greater than 100Hz but less than 10Khz, you can use both Tri-PLC High Speed Counter inputs to automatically monitor count and Frequency/Speed. Of Course, you can always use the two High Speed Counters if frequency is less than 100Hz. Keep in mind that there are only two High Speed Counters available on a Tri-PLC.

Collecting and displaying this data real time is not a problem. Storing the data in the PLC depends on the different type of data and how often you store these data. There are approximatly 4000 16-bits DM[] registers available for storage in PLC. If you are doing only end-of-day data storage, the PLC internal DM[] registers can handle that. If you have to do massive data storage, you can connect the PLC to a PC. The PC could store the data in hard drive or cd so now you have a unlimited amount of storage space.

If you need technical help designing your PLC based system, please let me know. I am a PLC Systems Integrator already helping many Inventors currently using Tri-PLC's.

Frequently Asked Questions / Re:RS232 to USB port adaptor
« on: February 13, 2005, 07:36:10 AM »
I have been successfully using an Edgeport/1 USB to RS-232 Converter for about a year. The manufucturer is Inside Out Networks (www.ionetworks.com) and the vendor is B & B Electronics (www.bb-elec.com).

Make sure that in TLServer you select the right communications port (Com1, Com2, etc) assigned to the physical USB port your USB Converter is connected to.

Technical support / Re:T100MD step motor speed control
« on: January 02, 2005, 09:00:25 AM »
What are the exact STEPSPEED and STEPMOVE commands parameter values that you are using to control Step Motor.

Are you executing STEPSPEED command first before executing STEPMOVE command?

Are you waiting until current STEPMOVE command is compleated before executing the next STEPMOVE command?

Is your STEPMOVE "count" parameter value at least twice the STEPSPEED acceleration parameter value?

Technical support / Re:Connecting and controlling a 12VDC Motor
« on: December 14, 2004, 11:16:42 PM »
The best way to control the speed of your 12VDC 9.0 Amps motor is to use one of the two PLC PWM (Pulse Width Modulation) outputs. They are usually rated for 10 Amps and can easy be buffered with a Power MOSFET to increase power to load. Then use the PLC PWM command to control the motor speed.

Technical support / Re:HSC Encoder processing high frequency vibration
« on: December 14, 2004, 10:58:23 PM »
What is the frequency of Encoder pulses coming into PLC HSC inputs?

Are you using a quadrature Encoder with pulse phase A and pulse phase B?

If you are using quadrature Encoder pulses, phase A must be wired to PLC Input #3 and phase B must be wired to PLC Input #4 that is if PLC HSC #1 is being used. If PLC HSC #2 is being used, then, wired phase A to PLC Input #5 and phase B to PLC Input #6.

If you are not using both quadrature Encoder pulses, for example if you are only using phase A let us say connected to PLC Input #3, then, Input #4 must be permanently disconnected (open) in order for leading-edge of pulse arriving at Input #3 to increment count. If Input #4 is permanently connected to ground,  the leading-edge of pulse arriving at Input #3 decrements count.

I am going to assume that you are using single phase (not quadrature) and the other HSC complement input is changing states and thus causing a reversal in direction of count .
