Technical support / Data down load
« on: June 09, 2009, 02:46:40 PM »
Hi
Our company is looking at building another bitumen spray truck, the last one used two T100MD1616's with touch screen as control system. Spray run data was displayed on touch sreen at end of run an recorded manually by operator. This time  they require data down load via USB memory stick. Is there some way of doing this direct from plc or do we need to use suitable touch screen ?  

Regards Pete

PS   Whens the new F series going to be availible for markets
       outside USA and Canada  ??

Technical support / mouse wheel control
« on: November 30, 2008, 12:27:41 AM »
Hi

Has any one had any success in using the ardamax mouse wheel control program. If so what was necessary to get it up and running. I have tried to get the trial program to running but no luck so any thoughts would be appreciated. That side bar control is not one of trilogi's better features    :P

Thanks for the prompt reply      
As the input will be held low for long periods, will 1k be high enough to prevent any input power dissipation problems with a 28v power supply.

Technical support / PNP proximity sensor
« on: November 14, 2008, 11:52:02 PM »
Hi

Has anybody used  PNP  type proximity sensors to switch a T100MD input and if so what issues did you have ? also what value resistor did you use to hold the input low ? Normally I use NPN type but in this case the machine already has PNP type fitted , cost to change is a problem.

  ::)

Thanks for your time

Technical support / PID value
« on: August 22, 2008, 03:09:42 AM »
Hi

Starting a new project in which I need to use the PID function in the T100MD  888
What I would like to do is use the T100MD as an variable engine speed governor utilizing the 0-5vSetDAC o/p and monitoring drive shaft speed for feed back  keeping within  120  (700rpm)  to 230   (1250rpm)   Hz limits  The operator will vary speed  with increase and decrease speed switches
I assume result of these custom functions  ( Stored DM[11] ) will become the Set Point value.
What I'm not sure about is how to work out what values to use in the PID compute function.

Any help appreciated
Pete

The program cycle will take approx 30 sec to complete so do you think it is necessary to use a clock pulse in that line  ?


Typo  sorry  J1939 is what we encounter most  it would be nice to use the PLC as a smart IO card to access the truck canbus  for our various special project requirements.

1.Thanks for that.  Next problem is with a PWM cust funct ,for some reason the output will not switch off when P=0 if the clock pulse  for the cf ladder line is 0.01 sec but if changed to o.1 sec the function works ok what do ou think could cause this ?   Should I be using a clock pulse with a PWM cf ?


2. Canbus protocol -    probably  J1937

Hi

In one of my programs a  custom function label  is highlighted in green What would I have done to cause this and is it bad.

Is a new version of the T100MD planned , and if so is it likely to be Canbus compatible


Thanks for your time

Technical support / mdtest program
« on: December 18, 2007, 10:50:39 PM »
Hi all
Two questions

1. Where are the instuction for operating the mdtest program? after installing into a T100MD1616 all it seemed to do was operate the outputs, is there more it will do ?

2. How static sensitive is the TPIC6A595NE ic ? Is touching the pins liable to damage it ? I beleive this can be an issue when handling cmos devices.

Technical support / Re:PLC freezes temporarily
« on: December 11, 2007, 12:31:32 AM »
Back again, after testing RS485 wiring, ran temp cable between master and slave outside vehicle,  also tried with out MX RTC fitted, no improvement. The ground distance covered is also recorded and this appears to be inaccurate and erratic. I had a look at the program and I noticed that the ground speed signal ( around 100Hz at operating speed ) does not use the high speed counter. Could this be a problem ?

What do you suggest is the best way to test RS485. The system has been working fine for about 2 years now but until 6 months ago it didn't have the MX -RTCs fitted. This may have been when the problem started but I,m not sure about that. I was informed that unless there is a lot of electrical noise due to the nature of the RS485  non twisted wires would be ok and up to now that seemed to be right. Shoud I run a temporary TP link. I'm making up 2 signal generators to substitute pump and ground speed ,as testing by spraying bitumen is not an option.

Technical support / PLC freezes temporarily
« on: December 09, 2007, 09:45:48 PM »
Hi to all

Im having a problem with a control system we built for a bitumen sprayer. The trouble is that the system will freeze occasionally for about 0.5 to 1 second causing chaos on the spray run. The system uses two T100MDs connected in master/slave configuration via the RS485 connection. Both PLCs are fitted with  MX-RTC battery/data modules. The  Slave unit monitors bitumen pump speed and switches 10 selectable spray nozzles.  Master unit monitors ground speed, touch screen, and control switches, it also controls bitumen pump speed. It appears that some conflict is taking up all the master units time, when the fault occurs the numbers on the touch screen  also freeze. Both PLCs have  been replaced, but fault still happens. Could the MX-RTC module possibly cause this by being faulty or data storage full ?

Thanks for your time

Technical support / Re:Automobile applications?
« on: June 15, 2007, 11:15:33 PM »
I use the both the  888 & 1616 for automotive applications in 12 & 24 volt systems and find they give good reliable service as long as you put diodes across any solenoid coils you are controlling and you use the recommended power input protection.  Although some times I have had problems with noise on analog signal inputs, but a filter and/or averaging the signal input seems to take care of that.  Also their versitility means I dont need to keep lots of spares.
