Technical support / fx2424 output current
« on: December 05, 2018, 03:59:37 PM »

I have an application where I need two more outputs which can handle more current than 250mA as possible with outputs 17-24
I have used all other outputs with higher capacity.
Is it possible to use two outputs in tandem to drive a single load or must I use a SSR off board to handle the load?
I am driving a 400 mA at 24vdc solenoid.
The solenoid does have snubber diodes for the inductive kick

Technical support / Save as problem 7.12 build 3
« on: October 03, 2017, 10:26:09 AM »
I updated to Trilogi 7.12 build 3 this weekend and discovered a problem.

If you do a  "save as" of a PLC program with a date in the file name like PLC 10.3.2017 rev 1  it wont save the PLC file correctly.

If you save it, is does save a file in the desired location, but you can't see it to reload it. If I look with file manager a file has been saved to the directory, but it has the file extension  FILE  instead of the desired PC7 file type.  

If you remove the date with separating periods from the file name, it saves correctly. Windows has no problem with the inclusion of periods in the filename.

In previous versions  of Trilogi the inclusion of the date with periods did not cause any problems.

Technical support / Fx2424 analog port read issue
« on: November 01, 2016, 02:23:13 PM »
I have a very strange ADC issue on a Fx2424

With a simple ADC test program (attached) I show no ADC inputs when in online monitor mode on the lines 5 and 6 as I would expect ( they show DC voltage on the inputs with DVM of between 1.5 to 2.5 volts from attached pots). I show a ADC value of 4091 on line 1 with nothing connected and DVM voltage shows no voltage at the input. The 5 volt reference voltage supply is not being pulled down by the pots.

Have run this on two different Fx2424 with same result.

Disconnected everything from the PLC except the analog input daughter board ( and I swapped those also) Ethernet and 24VDC coming in clean. If remove the analog daughter board analog 1 register stays at 4091 when watch with online monitor mode.

I suspect I have developed some kind of software/firmware version issue.

Now have:

Tri version 7.11 build 04

Java 8 up to date

Swapped my router and cables, same result.

Scoped the 24VDC – nice and clean and 24 volts

Tried different scan times for the read, no difference.

When I run online watch I see nothing for ADC inputs 5 and 6, 4091 for ADC line 1 and

The variables assigned for the ADC reads show nothing except input 1 which shows 4091

What am I missing???

Technical support / Fx2424 analog 5VDC current increase?
« on: October 13, 2016, 10:34:29 AM »
My application is pulling the 10ma 5VDC ref voltage down on the Fx2424. If I add an external 5 volt source, all works well.

I remember one of your boards allowed changing a resistor to increase the current. I don't see that in the Fx2424 manual.

Any way to do this on the Fx2424 so I don't have to add an external supply?


Technical support / Printout enhancement
« on: July 29, 2016, 03:48:01 PM »
Currently if I have a program loaded on your development PC and want to print out the Custom Functions the only selection is to print all of them out between X and Y.

During development you may have numerous custom functions that get made to test etc which you don't want printed out and are not in the active program.

If the print command had an option to print only the Custom Functions that are used in the loaded active program, it would be very helpful.

Technical support / Fx2424 ADC display in Online Monitoring
« on: June 22, 2016, 02:44:13 PM »
I discovered when starting to debug a new program that the ADC display window in Online Monitoring
does not show a value unless that ADC line is read in the program periodically.

I assumed this was raw data for the ADC line and was always shown if there was voltage between 0-5 VDC
even if not called by the program - not so!

The statement in the manual on page 5-4 is not clear that monitor in includes the raw ADC display Online Monitoring monitor values .

I suggest changing the monitor program to display NA instead of 0 in the analog monitor windows for analog line that are "Not Active" (no basic statements referencing that analog line currently) it would aid in debugging.

Technical support / Fx2424 Input current

In order to pull a single digital input low on the Fx2424, how many milliamps  must be handled by the output of the connected device to ground?

Technical support / A nice feature suggestion to STEPMOVE
« on: April 20, 2016, 09:56:32 AM »
The addition of descriptive labels on variables has greatly helped creating programs rapidly.

In the STEPMOVE command, when you specify a relay to be activated at the end of the STEPMOVE it would be very helpful to also allow the use of an underscore and a descriptive label identifying the relay being activated.

STEPMOVE 1,22000,36  is more cryptic than STEPMOVE 1,22000,36_X_PLUS_DONE_RLY

Appreciate your efforts on the development of this fine program.

Technical support / Fx2424 and MD-HMI I/O addressing
« on: March 29, 2016, 04:29:48 PM »
I did not see and example I/O addressing when using MD-HMI with Fx2424 and EXP1616R expansion card.

I believe Key 0 should start at input 41 and end with F4 on input 56.

LED1 would be output 65 and last F4LED would be at 72.

If this is not so, please give correct addressing.

Technical support / FMD88-10 HSC
« on: December 23, 2015, 04:21:23 PM »
I need to use the HSC to count a single channel square wave input without a second input in quadrature. The frequency of the count is 2000Hz maximum.

How can this be done. I willing to give up the phase B input line.

How can this be done?

Technical support / PWM output frequency stability
« on: December 10, 2015, 10:58:30 AM »
I am using Fx2424 to drive a servo amplifier.  The frequency generated by the Fx2424 will be in the range of 200Hz to 10KHz. The accuracy from the manual looks good for my application.

I would like to know how stable the output frequency is once set. My concern is no so much the accuracy but once the frequency is set, how much does it drift around ?

Technical support / An opportunity for improvement
« on: November 19, 2015, 01:19:34 PM »
I was doing a quick test program when developing a MT8050iE HMI interface.

I noticed a complier error when it reacts to this bit of code with a simple error in it.

I am running the latest Beta, latest Java on windows 7

When you do a compile to test the code, it apparently sees the code problem, and flashes the complier error message, but it remains on the screen for about 1/100 of a second (just a flash) , and then returns to the ladder screen, no error message etc.

If you didn't know the regular process it goes though compiling , you could be surprised.

Technical support / Program forward compatability
« on: November 03, 2015, 02:35:26 PM »
I have a program I wrote for F2424 on TL6

I wish to move this program onto a new machine using Fx2424 and TL7

How can this be done?

Technical support / MT8050i HMI ethernet
« on: September 17, 2015, 08:40:16 AM »
I'm using Fx2424 connected to MT8050i HMI via Ethernet through a small switch used only between the two devices and my programming PC. In my application the display works well and is only used as a display of information, no input.

The issue I have s that occasionally the display pops up a window that says "PLC no response" which displays for a couple of seconds then disappears. I assume this is happening because the PLC does not respond to the HMI requests for updates in a timely manner and the HMI times out showing the error message.  

Where would I change a setting to allow more time before this message displays? I've looked in the HMI application and don't see anything, possibly this is in the OEM driver for your PLC?

Technical support / Fx2424 PWM output
« on: September 15, 2015, 09:10:02 AM »
I have an application where I need 3 step and direction stepper outputs and 1 PWM output. I really don't want to use a Nano just for a PWM channel output if possible.

In my case I do not use outputs 7, 8 for stepper phase outputs, I would like to use PWM output 3 while still allowing stepper 1 step-direction output mode to function.
