Technical support / Re: permanently latched input
« on: March 28, 2020, 08:05:03 AM »
Never did anything to the SmartTILE-fx board.  I've already ordered another FX1616-BA because I need to get this HVAC equipment back to a functional status.  I'll email for an RMA.

Technical support / permanently latched input
« on: March 27, 2020, 09:32:17 PM »
I have a FX1616-BA.  The DIO channel led #14 remains lit, even without any input and DIO #14-16 don't properly sense any input.  I've reset the board but nothing seems to fix this problem....is the board toast?

Technical support / Re: ADC not being read
« on: February 29, 2020, 06:50:48 AM »
I have that circuit in my program with a 1 sec trigger and I verified that it's being executed by monitoring DM[4]

Code: [Select]
DM[2] = ADC(1)*10000/4096
DM[3] = ADC(2)*10000/4096
DM[4] = (DM[4] +1) MOD 4095
SETLCD 4,1,"Water I/O Temps="+STR$(DM[2]/10) +"."+ STR$(DM[2] MOD 10)+CHR$(223)+"C"
I've even tried running the sample ADC program and get the same result
I've even tried it on a Nano board with the same result

Technical support / ADC not being read
« on: February 28, 2020, 02:24:31 PM »
I must be doing something stupid.  I'm trying to read the ADC values but the online monitoring of the FX1616BA shows all of the ADC channels grayed out and showing 0
How do I enable the reading of the ADC channels?

Technical support / Re:cannot login to plc
« on: July 19, 2018, 07:55:36 AM »
it isn't enabled and even if it was setting SW1-3 should have disabled it
Is there a way to completely restore the PLC to factory settings?

Technical support / cannot login to plc
« on: July 17, 2018, 05:49:17 PM »
I worked on F1616BA the other night....everything seemed fine
Today I can't connect and keep getting error "Please check username/password and Retry"
I tried setting SW1-4 and powered up which put it in a paused state but still couldn't log in.
I can login to PLC via the internet port but not the ethernet port.
Disabled firewall and that didn't help

never mind, found a demo that solved the situation.
using a latch & timer circuit  :)

Technical support / HVAC controller
« on: June 22, 2018, 11:03:38 AM »
I'm new to programming the PLC
I'm trying to design a zoned HVAC system controller for a dual stage heat pump.
Most of the ladder logic is working but I'm trying to get a few extra features
After a heating/cooling call is finished, I'd like to keep the fan running and damper open for a set period of time to flush the conditioned air out of the system.
so, what is the most efficient way to create a limited time pulse width on the falling edge of a relay coil so that when the heating/cooling call is finished the fan runs a little longer?

Technical support / nano baud rate options
« on: June 02, 2015, 04:48:57 PM »
I'm trying to add a NANO as a slave device on a rs485 cable but am unsure if I'll run into problems with setting the baud rate compatible with the other devices on the cable.  The other device on the cable only supports 2400/4800/9600 and 19200 baud rates with 8,1,n
So would I use 1st.scan and create SETBAUD 1,4 to initialize the NANO upon powerup so that it can communicate with DAQFactory on the same comm port as the other device?

Technical support / using digital input to measure AC voltage frequency
« on: May 31, 2015, 05:11:57 PM »
I'm trying to use a Nano to measure the heat generation by a solar water capture system.  I was going to use the two AC inputs for input/output temperatures and have a paddle wheel flowmeter which generates a triangle wave 3VAC output where the frequency is linearly related to flow rate.
Can I directly connect the flowmeter output to one of the digital inputs to measure the frequency or do I need to do some signal conditioning?

Technical support / Re:setting baud rate
« on: October 07, 2013, 07:51:46 AM »
I'm new to programming the plc...do I have to trigger this or can I put it as an initialization sequence when the plc powers up?
Is there a way to automatically run an initialization sequence when the plc powers up, the default baudrate, etc won't work with the other equipment daisy chained on the modbus

how can I change the serial port settings. I connected to a F1616 with default settings of 38400 @ 8/1/n but sending a command string via FServer serial port setup SETBAUD 3,&HC4 returns ER*

I'd like to start logging to mysql server also but can't find any documentation for this capability.  Could you share please how this is done ;D
