Technical support / Google home hmi development
« on: July 20, 2017, 07:44:23 AM »
I saw some potential in the new google home device as A hmi. I got talk to their support personnel and they said they don't think it supports modbus tcp but admitted implementing it would take google home to a whole new level and seemed exited to pitch it to there engineering team. they might want to install modbus compatibility in an update once they realize it's potential because are still adding extra functionality and are open to the ideas others so they might be willing to listen to pitch from a plc manufacturer. they are already using it in home automation and business applications. Just thought I would throw that idea out there. The TRIPLC web HMI is still nice but It would be pretty neat If my F2424 has a voice box.

Technical support / Re:PLC Freezing Problem
« on: March 15, 2015, 10:22:02 AM »
When the crashes happen it is as far as i remember when i activate I/Os. but there is no particular one that causes it. sometimes it happen whens communication slows down. like for instance i activate and I/0 and have to wait 5 to 10 seconds for the PLC to comply.
The communication drops out and a dialogue box pops up and tells me to check corporate firewall. sometimes I can re establish a connection a few minutes later and other times i need to power it down after about 2 days of being unable to connect. Most of the time the program continues to run but it i'm left unable to connect to it.
It happens with the example programs and programs I have written.
I find that there are other things to that are buggy like for instance i have an lm34 reading converted to    
 °C telling me that the temprature is 22 °C  stored in DM[100] and I have written
setlcd 0,1, chr$(1)
setlcd 0,1, chr$(12)
setlcd 1,1, " Room temp is  " + str$(dm[100]) + chr$(223) + "C"
it displays on both the WEB AP and ONLINE MONITOR screens
Room temp is 22 BOC
 instead of
Room temp is 22 °C
I believe the r81 on the plc's hardware info stands for firmware revision 81. my  Itrilogi software might be corrupted so I guess it wouldn't hurt to update the firmware and get get the Itriogi 6&7 file off you guys again.

Technical support / PLC Freezing Problem
« on: March 12, 2015, 01:11:19 AM »
I have a weird freezing problem with a fx2424.
It only ever happens when i trying to control it via online monitoring or the hmi web app.
I loose all connection with the plc end it appears to freeze the whole plc's operation.
It happens so often that i can't really trust it to do anything unless I do not attempt to establish communication with it of any kind once it is up and running.
there are no error lights on at all. the latest freeze occurred when i tried to send an IR signal with the web AP to a 9 LED emitter and it froze the output (output 5) on the on position.
I used a camera and the 850nm LEDs are lit up. also i wrote a test program to see if the problem was just a communication one and it seems that the plc has crashed completely.
if i switch off the power then turn it back on it fixes it self until i try to connect to it and i would say 1 in 3 times it crashes
what could be going on?

Opinions & Feedback / Web server HMI suggestions
« on: February 15, 2015, 11:00:24 PM »
The web HMI it a great idea and works really well. But it would be nice if you had a couple more things you could tweak like for instance the push button behavior. You click it on then click it off. If I wanted to start a custom function up you would want a button that stays on for only 1 scan cycle. And the HTML calls for java script stored on web servers. it would be nice to be able to alter that code a bit if you had the smarts and upload it with the HTML file if you want to sacrifice a bit of memory. And some DIY guides on the java script key functions etc.

Thanks for the advice there. i see now i'll just set F max = 5v on the VSD, at the risk of looking stupid, i'll ask anyway could I make a connection from the fx2424 DB15 pin 14 to VSD FR and pin 9 (0V ) to FC leaving FS unconnected? would that give me a good connection to DAC #1? the FS 12V looks a bit scary. The VSD is already set to Voltage type input.

thanks for your input. i thought about PWM but even filtered wouldn't the ripple be a concern? I'm trying to read up on the times 2 multiplier electronics and also maybe the data acquisition and control
modules none i which i know much about but i'm not sure which way i should be going for atm. all a bit of a learning curve really

Hi Guys have i have a VSD that i want to connect to a fx2424. it has a 0-10v input to control the output frequency. i put a link to the Manuel. on page 22 of 89 is the description I have to work off. is there anyway to make the fx2424's 0-5V outputs compatible ?I'm new to analogue outputs.

Opinions & Feedback / 3d print library for triplc projects
« on: April 06, 2014, 05:46:51 AM »
I’m very impressed with the fx2424 and all your other products, I know a little bit about 3d printing, but If this site had a triangle research 3d printing file library with specific printable accessories for your products along with other relevant type project prints. it would make this site revolutionary. Has the Triangle research team thought about this approach yet? It would make this site the first stop for any developer. It wouldn't be such a bad marketing idea. What does every one think?

Technical support / Re:Dead Ethernet Connection
« on: March 28, 2014, 11:01:50 AM »
PROBLEM SOLVED
the Ethernet port lights lit up all of a sudden but i was still having trouble with it for a while. I was trying to ping it and looking up all my attached devices through my router set up page with no success .
I solved it by connecting to the fx2424 via serial port and ran i-trilogi went to controller tab/ Ethernet & adc configurations/ Retrieve Parameters from plc.
it gave me the following info
ip address : 192.168.1.5
gateway IP: 192.168.1.1  
my real gate way and 2 PC's IP's are
gate way IP:192.168.0.1
PC No.1      : 192.168.0.2
PC No.2      : 192.168.0.3
So i changed the second last digit from (1) to a (0) on the Ethernet configuration to read
IP Address :192.168.0.5
gate way IP:192.168.0.1
hit the [Save Parameters to PLC] button and that fixed everything.

Technical support / Dead Ethernet Connection

Hi Moderator,
I have a 6 month old Fx2424 i have just started to use and when i plugged it into the router via Ethernet the yellow light never came on. I Tried different cables, different router ports. I Looked for it’s mac address through my router set up page and got nothing. Everything else I plugged into the Ethernet cables works fine. Is There a chance I have a defective Ethernet port on it?  The RS232 port works fine

Technical support / Re:Hotplate heat Control
« on: March 24, 2014, 03:52:32 AM »
Thanks for the advice Gary D I'll have to digest that. Much appreciated. I have a bit of time to read up on those functions and tinker with them a bit I should have it running properly some time next week. i'll let everyone know how it all paned out for anyone else who wants to do something like this.

OOPS I meant the SSR was controlled by output 1 not input 1 thanks

Technical support / Hotplate heat Control
« on: March 23, 2014, 09:15:22 AM »
Hi, I have a large sealed cooking pot and I need to keep it at between 75 - 85 degrees Celsius for 90 mins at a time.
I have an electric hot plate hooked directly into a 240V 50 HZ AC supply Via a Solid State relay controlled by input 1 of a  Fx2424 and a sealed lm34 hooked into ADC 1 reading the temperature.
So I was thinking of trying to work out the PID function. But because it is a 50 HZ ac supply i don’t think using PWM would work well. I was thinking of a low switch rate duty cycle control to regulate the temperature similar to what the simmer stat would do. Should i be use the pid function or try to use 2 timers and try to use a custom function to alter the set values? Thanks for the advice in advance.

Technical support / Re:can't use tbasic
« on: May 28, 2013, 08:53:13 PM »
so if i wanted to do structured programming with many subroutines IF THEN GOTO in custom fuctions are out of the question i guess. would you suggest perhaps t basic operating master control relays? Allen Bradley has different programming layers for subroutines. thanks for you imput
