How can we send SMS from an android or ios device in PLC?
I believe that's not possible at this moment.

I was reviewing some of the information on your TBASIC Custom Function Help site (http://www.triplc.com/TRiLOGI/Help/tbasic/tbasicIntro.htm) and noticed that some of the images do not show up.   I pulled up the same page on another computer and the same images are missing.  And it doesn't seem to matter if I'm using FireFox, Chrome or Internet Explorer...the images are missing in all 3 browsers.

Primarily, the missing images are located in sections 1. Overview through section 2.3 Search/Find.  I did not read thru every topic so there may be more.

Just thought you'd like to know.

I'm very little into perusing, but rather some way or another I got to peruse decent data on your site. Easy to comprehend and accommodating. barnet tree sunderland

Technical support / Re: TCP-IP and ID goes to 0xFF

Thank you for all these information.
Yes we have read many times the User manual, but obviously we are missing a point ...
Is there a kind of 'automatic' (not programmed by us) routine that interact with the EEPROM ?
We will review again our program and report to you.

Does your FMD PLC have FRAM-RTC?

If the PLC does not have FRAM-RTC installed, then are you using a power failure interrupt routine to save parameters using SAVE_EEPx to non-volatile memory  during a power failure? Or is your program running the SETTIMERSV or SETCTRSV command during operation and need to be saved to non volatile memory before power failure?

Please refer to Section "1.7.2  Non-Volatile Data Store" in the FMD PLC User Manual which explains how the pseudo EEPROM works and why you could lose data if power failure interrupt routine is not given enough time to back up the pseudo EEPROM data to flash memory.

When you power down a machine by turning off the AC power, the DC output of the power supply usually have enough capacitance to gradually decay to zero so the power failure interrupt routine can work properly.

When you press the emergency stop button, did you cut off the DC power supply to the PLC immediately? If so then the interrupt service routine is not given enough time to save the parameters. What happens is that the flash sector is erased but the CPU did not have enough time to copy the pseudo EEPROM data to the flash and therefore you lose the Ethernet parameters as well.

If you wire your emergency stop button such that it only cuts off power to the I/O but not to the PLC, then this issue should not happen.

Alternatively, organize your program so that if you need to save some data to non-volatile memory or need to change the timer or counter set values using the SETTIMERSV or SETCTRSV, then do so in the main program itself and execute the SETSYSTEM 252, 0 command to backup the new data to the flash memory  immediately so that the CPU will not attempt to save the changed data to flash memory during power failure. Of course you should take into consideration that there is a 100K erase/write limit to flash memory and therefore your program must avoid erasing/rewriting to the flash memory so often that exceeds its life cycle limit and wear out the flash memory.

Technical support / TCP-IP and ID goes to 0xFF
« Last post by acxysty on April 13, 2022, 07:29:47 AM »
Dear All
We are a FMD-88 in a larger electronic device to exchange modbus information by RS232 and RS485.
From time to time  we are losing  TCP-IP and ID communication parameters on a power-down/power-up sequence. Typically an emergency stop sequence.
As it happens rarely, it is difficult to understand the reason behind that.
We can recover the FMD using TLServer over RS232 to retrieve a "new" ID, to re-configure / re-connect again by TCP-IP
What could be the reason of that ?
Does this has to do with eeprom ?
Thank in advance for your ideas and support.

General Discussions / steper motors like a dc motors
« Last post by ROBBYG43 on April 02, 2022, 11:02:41 AM »
Is there any way to make a stepper motor work like a dc motor, that is, with a relay on  to run continuously until the relay turns off?
