Technical support / new question on old board
« on: November 07, 2013, 04:27:26 PM »
I have a T100MD2424+ that has been in use reliably for about 8 years. I am looking at changing a portion of the machine. I am wanting to know if the 4 HSC counters on inputs 3-6 can be used independantly to to count pulse 4 streams ? I know that 3&4 make a pair for quadrature decoding as do 5&6 I just want to verify they can be split having no count interaction.

Technical support / Editor version issue????
« on: October 29, 2013, 02:14:34 PM »
I am working on an old program of mine and updating it. When I bring up the code, I have no custom function numbers and cant edit the custom functions.

I suspect a version issue or overwrite/ save issue.

Ideas on how to resolve the issue?

Technical support / RS-485 vs Ethernet between two TRI PLC
« on: February 15, 2013, 09:25:31 AM »
I have an application where I need to have communication between two Triangle PLC'S I need this to be very robust and the data rates will be low. The enviroment is outdoors or in a light industrial area. Possibly some RF around from devices in the facility. A couple of stepper drivers are also in this system.

I would like to use the Ethernet using non-shielded CAT5 or CAT6 cable so I could easily interface to PC'S The RS-485 looks to be very robust but not my first choice.

Based on many application of your products in many situations, which is a good choice?

Technical support / A great new stepper command for wish list
« on: October 29, 2012, 01:21:41 PM »
I have used the stepper inder on numerous applications. The boards work very well.

It would be very helpful to have a MOVEHOLD command. The command would cause an executing STEPMOVE to decelerate to a stop and hold at zero speed until commanded (input goes high) causing the motor to ramp back up and complete the STEPMOVE command.

Thanks for the great products.

Technical support / Zero speed sensor question
« on: June 19, 2012, 10:22:09 AM »
FMD1616-10

I am using PULSEFREQUENCY to determine when an encoder input bit to HSC has zero or very low frequency (has come to a stop) . The issue is it detects the state very slowly - maybe 2-3 seconds. I have tried many ways of coding it with same results.

Possibly another tool is better at detecting low speed state change faster?

Technical support / FMD1616-10 step stop issue
« on: May 23, 2012, 09:22:51 PM »
I have a program that uses stepmove command. Stepspeed is set before stepmove. I need to stepstop the move at any time in the move. I have done this many times before with other Triangle boards.

The step move will start and if I issue stepstop while step move is still ramping the step move will stop when step stop triggered.

If the stepmove reaches full speed (not in ramp) stepstop will not stop the move. In addition if I am watching program from my PC, the PC is kicked off (looses communication link) until the stepmove completes the 5000 step move, then it starts up again.

I have tried many versions and removed all from program to just have bare minimums with same result. I think the ladder scan is stopping during the maximum speed portion of the move and resuming when the move terminates - why?

Any ideas?

Technical support / Different than documentation FMD1616-10
« on: May 22, 2012, 11:14:08 AM »
I have a FMD1616-10. The manual shows the common for the outputs as pin 9 of the output connector. The boards I have only have 8 points on the output connector.

I assume that the common is now tied to 0VDC on the board and has been removed from the connector. Am I correct in this?

If I am correct, it would be good to update the documentation to reduce confusion.

Technical support / Stepper ramp question
« on: May 14, 2012, 04:14:19 PM »
I have application that requires ramping to a stop during a STEPMOVE command and then resuming to end at the final position as defined in the original STEPMOVE.

I am thinking the STEPMOVE command is not designed for this. Can you supply the algorithim you use to for ramping stepper so I can create version in basic to meet my application need.
Thanks

Technical support / MD-HMI issue
« on: May 11, 2012, 03:51:58 PM »
I while back I asked about the correct key routine for my hardware( FMD1616-10, MDEXP1616R and MD-HMI)
I implimented what you suggested and it works - pretty well.

The problem is that if you hit or hold the key it will often change the displayed active input key from the correct key to one above or below the correct key. So if I press the 5 key when I am watching online on PC input for a second the 5 key may go on, then change to a 4 and then go back to a 5. All 0-9 Backspace do this. Seems like a scan-debounce issue to me.

I have tried various scan rates for the routine and checked it against other Triangle machines I have programed here, no help.

Suggestions?

Technical support / Trilogi update
« on: April 10, 2012, 02:15:48 PM »
I recently asked about updating Trilogi software on my desktop pc and your answer worked great.

I am trying to update notebook XP computer I use in the field from 6.30 to 6.43 the same way and does not seem to work wants to update it to version earlier than 6.30 that it now has installed. Appreciate help here.

Technical support / stepmove over write question
« on: April 02, 2012, 10:08:29 AM »
If I am executing a stepmove command of 10000 steps
and at 4999 steps into the move I execute another stepmove command on the same channel for 7500 steps:

Will the first command be terminated (decel and stop?) at whatever number of steps it has executed and the new command will take over and execute the new move of 7500 steps

Or will the second command for 7500 steps be executed after the first 10000 step command is completed?

Thanks

Technical support / Code example
« on: March 21, 2012, 04:16:45 PM »
I know you have a few examples of code included with your product. I don't see anyplace on the forum that is a repository of code examples.

I am thinking this would be helpful to many people who often are undertaking similar tasks.

Perhaps this exists somewhere?

Thanks

Technical support / Correct I/O assigments and HMI sample program FMD
« on: March 16, 2012, 12:10:19 PM »
I think I have the correct I/O assignments for my configuration of a FMD1616-10, MDEXP1616R and MD-HMI.

FMD inputs and out puts start at 1 and go up to 16
MD EXP 1616R inputs and outputs start at 17 and go up to 32
MD-HMI inputs start at 33 and go up to 48
MD-HDMI LED 1 starts at output 33 and ends with F4 led at output 40

Do you have example HMI program for this configuration as you do for other configurations?
Thanks

If you could provide link for download I would appreciate it.

Thanks

Technical support / Remote monitoring and control nano
« on: August 22, 2011, 03:02:06 PM »
I have a nano using 6.43 programming software on PC over ethernet connection through a small switch no other users.

I can load programs and monitor, make changes to memory. I am not able to change state of inputs with mouse even when remote control check box is checked.

T100MD allowed change of states either momentary or latched with mouse.

Is there some kind of setting need to allow this?
