Technical support / E10 PLC on Pause
« on: July 20, 2009, 10:47:01 AM »
Hello
I?m having an issue with an E10 PLC, but first I have a few questions.
1- What can possibly cause an E10 PLC to go in to ?Pause Mode? on its own? The PLC was unresponsive and when I connect my laptop to it the TRI software gave me a message that the PLC was in user ?Pause Mode?.
2- After resetting the PLC through the software from ?Pause Mode? only some of the logic is executed, from the second rung down. What can this be? Is like the PLC doesn?t detect the input to be on.
3- Power supply is 24 VDC with a SOLA power supply.

I have this PLC installed controlling a sump ejector pumps with a few relays interfacing voltages. The floats power a relay which activates input in the PLC. And the outputs power a relays that starts the pump. The PLC operation is very simple and straightforward. Input1 is activated output 1 is energized, Input 2 is activated output 2 is energized together with a timer. If the timer times-out and the 2 input still activated then energized the alarm and the last output will be energized to help with the load. For some strange reason this work for about a week, after a week the plc goes in to an unresponsive mode ?Pause? and it doesn?t do anything. This is the second plc and it is doing the same thing.

Please advice,
Ed

Yes that's what i did i overnight a set of IC LT1785  reset the plc and now is back to normal.


Thanks

Hello,
Question, One of my guys at a job was installing a TM2424 Controller and accidentally wired the 24V to the RS485. Now the controller is not responding.
What can be the problem and the solution?
He also installed a 1000?F 35 VDC Cap.

Hopefully the plc still good

If is just part, can you advise where to buy them from if is not from Tri.

I also use the WinTRiLOGIC for the TM888+ too.  I'm doing the same thing as you're showing me. But it doesn't work even if i click on the side arrows it doesn?t go over counters.
I will re-install the program again.
Thanks.

Sure, I see the Special Bits on the Drop down box but is not allowing me to select it. I click on it but it goes back to the previously selected item.

Thanks.

I'm just detecting a Transfer switch from Normal power to Emergency power. that occure in 10 ms so the units stays with no power for 10 ms.
I programmed the E10 and it detect the voltage drop faster than my eye can blink it worked. i just need it to add the suppressor to protect the plc.
 
in my version of winTRiLogic 3.5 for the E10 i don't get that table with the Special Bits. i can see it but can't select it.

Thanks.

Does the E10 support Special Bits like the other please? if so how can i add one.

also, I'm designing a surge protector for industrial air compressors, i have the plc connected to the unit CT to 24V. i like to add a suppressor to the supply voltage, can you guys recommend a type of suppressor i can use.

Thanks,

TRY IT THIS WAY AND SEE IF IT WORKS

IF DM[1] < DM[2] THEN
SETBIT RELAY[1],5
'CLRBIT RELAY[1],5
ENDIF

RELAY 5 ON BANK ONE THE RELAYS GO FROM 0 TO 15 PER BANKS SO IF YOU WANT TO TURN ON RELAY 18 THEN YOU GO SETBITRELAY [2],1 THE SAME TO CLEAR CLRBIT RELAY[2],1

EXAMPLE:
B1 = 0 TO 15; B2 = 16 TO 31 BUT PROGRAMICALLY WILL BE 0 TO 15 TOO WHAT MAKE THE DIFFERENCE IS THE BANK NUMBER 1,2,3,4 AND SO ON. SETBIT RELAY[B2],1 = TURN ON RELAY 18 REMEBER WE START FROM 0 SO RELAY 16 IN REAL TERM IS 17 + 1 = #18 ON BANK 2

USE THE SETBIT TO ENERGIZE USE CLRBIT TO DE-ENERGIZE
I HOPE YOU GET IT...

Well as far i'm concern there's not a place where a PLC or a MPU;MCU will fit, think of them as a person that will be doing exacly what you want to do when it has to be done. i have use the PLC's on cars,Home automation System,Fire Alarm System,Industrial application, and even a sound control system for cars. you will have to know exacly what you want to do and see the type of controller Trilogic has to offer they are easy to use and relyable. you can't bit that.

The on an Off part the plc will do that no problem, the other things you want to do is up to you and the plc will defentlly do more than ON/OFF...


I hope that helps...

« on: July 14, 2005, 08:45:34 PM »
well Lets look at the P.I.D. and how these parameter affect the Output

P = PROPORTIONAL BAND IE: IS THE AREA AROUND THE SETPOINT WHERE THE PLC IS ACTUALLY CONTROLLING THE PROCESS

I= INTEGRAL (RESET) IT CORRECT ANY OFFSET BETWEEN THE SETPOINT AND THE PV(PROCESS VARIABLE) AUTOMATICALLY BY SHIFTING THE PROPORTIONAL BAND. IT REDIFINE THE OUTPUT REQUIREMENT AT THE SETPOINT UNTIL THE SP AND PV ARE EQUAL.
A VALUE TOO LOW MAY CAUSE CONTINOUS OSCILLATION IE: IT CAN OVER RESPOND, IF IS TOO LONG IT WILL TAKE LONGER TO SETTLE.

D- DERIVATIVE(RATE) SHIFT THE PROPORTIONING BAND IN A SLOPE CHANGE OF THE P.V. THIS IS THE BRAKES PADS OF THE PROCESS, IT PREVENT THE OVER AND UNDER SHOOT ON PROCESS UPSETS. THE RATE IS USUALLY SET LOWER THEN THE RESET.


SO THE "I" AND "D" THE HAVE MOST OF THE PROCESS CONTROL LIKE IN TEMPERATURE CONTROL SYSTEM IF YOU HAVE A SETPOINT OF 200?F
AND THE TEMPERATURE IS 150 NOW THE (I-RESET) WILL NOW MOVE THE PROPORTIONAL BAND TO SET THE OUTPUT AND THE (D-RATE) PREVENT THE OUTPUT OVER AND UNDER SHOOT.

      P.V. =150?F
0      |---->                   200?F                                   300?F
<-------------|--------------SP------------------|----------->
               100%             50%                  0%
                  |<---PROPORTIONAL BAND-->|

THE RESET MOVE THE PV FROM L/R AND R/L UNTIL THE SP AND PV ARE EQUAL @ 50%...
I'M IMPLEMENTING THE PID FUNCTION IN VB6 IF YOU LIKE WHEN I'M DONE I CAN GIVE YOU THE FUNCTION CODE AND YOU WILL SEE HOW EVERYTHING WILL TAKE EFFECT ON CLOSE LOOP CONTROL.
POST YOU EMAIL FOR LATTER. NOW I HAVE IMPLEMEMT AN OPC CLIENT PID CONTROL LETS SAY IF YOU USE ALL THE PID CHANNEL(1 TO 16) "IMPOSSIBLE" IN THE PLC THEN YOU CAN USE YOUR HOST PC TO DO SO..

IF THIS INFORMATION IS INCORRECT IN SOME WAY. FOR SOME OF YOU GUYS THAT KNOW THE PID LOOP WELL BETTER THAN I, FEEL FREE TO POINT OUT WHERE I MESS UP OR COMMENT IT HAS BIN A LONG WEEK AND JUST LIKE TO HELP A LITTER HAHAHAHA LOL.
i HOPE THAT HELPS...

Technical support / Re:decimal point on HMI
« on: June 22, 2005, 06:50:51 PM »
Hi this is what i do to show the Temperature from a Sensor on AI # 1 will show you the decimal point from 0 to 9 at real time, try it and see if it work.Simply Multiply it by 1000

lets say that the sensor is from 30?F to 250?F ;4-20ma
4ma/30?F = 814Cnt and 20ma/250?F = 4073 Cnt that's with a Resistor of 249 ohms 0.01%
If ADC(1) = 814 it give you a value of 299 wich we convert to 29.9 as String Data Type and a Count of  4073 is a value of 2500 wich is 250.0

Code:

T = (ADC(1) * 2000) / 4073
A = ((T - 400) * 2200) /1600 + 300 'Temperature scale of 1000

IF LEN(STR$(A)) <= 3 THEN
 A$ = "RM TEMP: " +  MID$(STR$(A),1,LEN(STR$(A))-1)+"."+ MID$(STR$(A),LEN(STR$(A)),1)
 ENDIF

IF LEN(STR$(A)) >= 4 THEN
 A$ = "RM TEMP: " +  MID$(STR$(A),1,LEN(STR$(A))-1)+"."+ MID$(STR$(A),LEN(STR$(A)),1)
 ENDIF

SETLCD 1,1, A$ + CHR$(176)+"F" 'Show it on the display like 75.3 ?F

Find the maximum and minimum Count of the sensor and change the Equation...
I hope that helps too

Technical support / Re:PLC On the TM100
« on: May 25, 2005, 03:14:09 PM »
well now is working fine but when it happen the output couldn't be energize either with the Trologic Program or with my Modbus Program but at the same time in the same conversation i could get data back like Input Status Registers status and even that spesific coil Status i got back also. is wierd right, it just didn't energize that output and a few hourse before it could...

I just Reset it and it when back to normal but i'm not sure if it will happend again...
Thanks...

On the Output why you have 12V i don't really know why but on the input if you don't have anything Connected to the AD input the input values will bounce up to the max Count but if you intall a sensor or if you ground the input it will stay at 0 use a POT so you can check the input with it. here some where they show you the schematic on how to do it too

Technical support / PLC On the TM100
« on: May 24, 2005, 07:14:08 PM »
Hey Guys somethig wierd happen to me with the PLC Digital Output#1
I try to set it to ON using Modbus ASCII and RTU and the Trilogic Software and i couldn't do anmything it didn't turn on until i reset the PLC. is that something Normal or what could be the cause of that problem is working now but i'm just wondering why...
Thanks...

PS:
Is that a sign of something bad is happening i didn't have any ladder schematic in the program that will hold off the Output either...

Thanks

Technical support / Re:4-20ma Calculation with 249ohms Res
« on: February 03, 2005, 12:16:33 PM »
Hey thanks for the reply

 i check the FAQ and is good but i did it the way it shows in the FAQ tread and i did it the same way i was doing it and i'm comparing it with a Gage at the same location and there is no difference the only difference i came across was on one of the sensor that by the company specify that is 4-20ma. it will output 4 ma when there is no pressure on the sensor but this sensor when is no pressure it output 3.5ma ensted of the 4ma but is fixed. that's the beauty of this plc that you can make any changed of any calculation and any process at any time i tell you i love it... Thanks guy... THIS PLC IS USER SUPER FRIENDLY BIG TIME...


1 more question what is the minimum clock speed that wont hert the cpu for the pidcompute function for the A.O.
and do you guys know a company where the make costume LCD with Keypad i need to get a quote on that if you know where...
Thanks guys..
