Technical support / F2424 channels
« on: June 13, 2012, 09:14:43 PM »
With this project we have an FMD1616 and a Nano connected via RS485 network. Also have the MMI6080 display on the network. It is supposed to run 2 stepper motors and 4 PWM devices. I was not aware that these cannot all run off one FMD1616. So, for an upgrade in the future I was looking into buying the F2424. My question would be, can the F2424 run 3 steppers, step and direction only fed into Geckodrives, and 4 PWM devices all at once? Does it have the channel capacity to do this? Thanks in advance.

Right now I believe this problem is interference from another circuit. There is a small amount of unshielded wire that I will change to shielded. Will reply back if we need more help with this. Thanks.

Paht (the OP) and I are working on this project together. Just to confirm what he is saying here, the servos are RC model type. They 'jitter', and seem to do this at a certain frequency, almost like a morse code type of signal to compare. This COULD be wiring interference, but to us it seems like something in the PLC code is doing it, yet this is a simple test program with little else in it.

Thank you, that is it exactly.

Yes, that's it exactly, need to control a number of RC servos (among other things). PAGE 11.4 of the users manual (the book)only shows For...Next statements, which users manual do you mean?

Technical support / Pulse width
« on: November 10, 2011, 06:58:33 PM »
Hi, I am trying to output a varying pulse width signal. I need it to be between 1ms and 2ms, in tenths of a ms. This is from a FMD1616. I read all the literature and is is unclear if this is possible. The older TMD 1616 had only a certain amount of fixed pulse frequencies I believe.

It would be used for systems control on a kit aircraft, landing gear sequencing, some other systems, not for basic flight control.

Hi, not sure if this is the right place to ask, but... looking for someone to do some programming for a project I am working on, dont have a massive budget right now but can pay some, anyone interested respond please, thanks.

Technical support / Re:PLC inconsistencies/ errors

Hmm, some good info. No, I haven't written to the PROM THAT many times. The PLC is running as I write this (At 12:45am) without problems, seems the last time I sent the program it was ok. All I have checked it, I am pretty sure the data the PLC is getting is ok, because the one time it went overtemp, the LCD also showed the temp to be as it actually was, and the PLC uses this same data to control. From what you said about Windows, I have a suspicion that that may be where the problem is, and will look closer at that, like you said, start the thing up in pure DOS and download from there. Thanks!

Technical support / PLC inconsistencies/ errors
« on: June 04, 2005, 10:02:25 AM »
I am using a T100MD 16-16 to run a composites oven. I upload a new file quite often to change max temps, ramp times, etc. Lately, the plc has caused some errors, random stuff like overtemp, or not finishing it's cycle, miscount on cycle times, etc. Nothing has changed with the program really, I just change a couple of parameters in it to modify the output, and it has always been very reliable in the past years. Can the PROM become corrupt over repeated downloads? I am using Trilogi in DOS, from Windows 98, is there something in this setup that could corrupt the compiler?

I use the TMD1616 with PID a lot, you have to first set PIDDEFINE, then PID itself. Quite easy to use.

Technical support / Basic in E10?
« on: September 02, 2004, 11:35:43 PM »
Can you use the same programming software for the E10NPN as the others, the basic plus ladder logic? Or if not does the applicable programming software have the custom function ability in it?

Yes, that worked, thanks. A question with the PWM, I need a 1 to 2 ms pulse, I have set the PWM at 62 Hz, and use a pulse between 90 to 160, what should the syntax be, do I need a zero in front, must it be four digits, etc.

Output 7 is PWM 1?? Gee, that would explain why the LED on 7 was lighting up, I was connecting to channel 1!! Thanks, OK, I'll go try it now.... !!

Technical support / Strange output
« on: July 28, 2004, 03:44:39 PM »
Hello, when using a T100MD-1616 PLC, I am trying to get it to output PWM to a small servo. I have followed the book letter by letter. I have the output as a sink, but never get any kind of output signal at all. It all runs ok in the simulation. I never see the LED on the board light up either. Anyone can tell me what my ladder rung should have on it that I'm missing? I use a slow clock signal to time it between another rung, and output with a custom function with the PWM statement in it.
