Hi,

I have a Nano PLC, how do I access the 11k Fram memory locations? DM[4001] - DM[1100]?? (I have the FRAM module installed)

I could use two of these connected to a gsm modem if I can find one that has an ethernet or RS485 port??

Cheers.

Thanks Gents,

Unfortunately, I won?t have a PC to hand as these are installed temporally onsite to collect the required values.  

We may need 2 or 3 per site and they maybe many meters apart.
I do need the half hour readings along with the day totalised value.  

Can I use the Print function to print to some external storage media?  

Can I create the CSV on an external drive like a SD or CF card?  Are there any such items in the market?

Hi,

I want to use a T100md888 as a data logger.  I will use 7 of the inputs to count pulses from various items of equipment.

We need to record the number of pulses every 30 minutes and total the readings for a 24 hour period.

The PLC needs to record this data for approximately four months! - This is where the problems arise......

Example

If I count the pulses on one input and store the value in 48 DM locations (every half hour x 24 hours) plus the total DM and the counter = 50 DM's

These 50 DM's = 1 day, if I run this for four months  +/- 120 days I will need 6000 DM locations plus a few spare for the required custom functions.

To use the other six inputs I will need 42000 DM locations!!

Is there a way to save the data to an external device or increase the DM size??

Hi Gary,

I disabled the modbus master and the PLC is now working without a glitch.

Is it possible to run the modbus master code in a separate sub routine to help the scan time even when the modbus device is present??  The modbus read commands does seam the slow the scan time down even when the comm's is good.

I suppose I could detect the read error and disable the read commands via some relays and timers for a period before trying again??

Anyway thanks for the info.

Cheers

Hi Gary,

I've been through the code and removed some of the 1 second contacts but the scan time is still slowwwww.

I added the  rung from your thread:

     0.24
----|/|----(0.24)

Output 24 flashes on and off in an but hangs in the on and off state for >2 seconds in between moments of fast flashing.

I do have a lot of custom functions (approx 50), one of these is a modbus master, currently the modbus device is not connected so there is probably some delay in the communication time-outs I'm sure.  I'll rem this code out tomorrow to see if that helps

The above aside, I would expect the PLC to pick up the input, especially as I hold the input high for 5 seconds!!

If you want to see the code I would be happy to email the program to you for comment.

Cheers

Hi,

Yes using the factory cable,  my "spare" LCD works with the leads OK.

Hi,  

I'm using an input to increment a DM value in a program we use on our standard panels.  DM value is used to change between LCD screens as we need to display data on the LCD

One niggle I have is that when I energise the input via a standard push-button, the PLC doesn't always see the input change state so the DM value isn't incremented.

After several attempts the value increments and the screen changes however this process can be somewhat frustrating.  

The program itself uses half the available program space, and I assume the reason for the intermittent reading of the input is due to the PLC resources being used elsewhere but I thought the scan time would be quick enough to pick this up??  Is there any way I can measure the scan time?

Can I prioritise this input into the PLC program?

Cheers

Hi,

Thanks for the info.

The contrast is fine, I have been able to get my hands on another LCD which works fine on both PLC's so it looks like the two I have are duff.

Any ideas why the LCD's would fail?  Is there anything I can do to try and bring them back to life?!?

Cheers

Hi,

I'm trying to get the LCD working on two TMD 2424's, both are using the 4 x 20 LCD.

I have loaded my program that is installed in four other installations but the LCD wont display any characters.

i have loaded a simple section of code that is triggered from Input 1 as follows:

SETLCD 0,1,CHR$(12) ' NO CURSOR
SETLCD 1,1,"KO POT CONTROL V" +STR$(DM[233],2)
SETLCD 2,5,""
SETLCD 3,3,"WWW.BCSYS.CO.UK"    'SETLCD 3,3,"WWW.BCSYS.CO.UK"
SETLCD 4,7,STR$(TIME[1],2)+":"+STR$(TIME[2],2)+":"+STR$(TIME[3],2)

Both PLC's are behaving exactly the same, both PLC and LCD were ordered at the same time.

Have you had any problems with either the LCD or the LCD port?  is there anything I can do to test the LCD or LCD port?

Cheers

Hi,

It Works!

It still wont work from the start menu or the jar file in the program directory.  It only works if I run the bat file.....

I receive an administrator warning asking me if I want the run the java environment, after clicking OK the server starts. - not ideal but it will keep me running!

Any ideas why?

Cheers

Hi,

It wont run from the start menu.  The jspWin.dl is located in the C:\Program Files (x86)\java\jre6\lib\ext\x86 directory as described in your email.

Hi,

I'm running W7 x64 and I have a problem with the server.  I can run TL6 no problem but the server will not start.  

I modified the bat files as described but the server just wont start up.

I put a pause in the bat file and this is the text:

Hi,

Thanks for the response.  I was only thinking of going up to the base of the IC i.e. the soldered part so would only be 1-2mm at a guess?

What is the heat dissipation of the PLC (F series for example), some of the environments I work in are very unforgiving and I would worry about the final temp of the PLC in a sealed type box.

Cheers

Hi,

I was aware of being able to use the relays but unaware of being able to use the SETbit function for DM.  this is great news Thanks!

Sorry,

Giving you a bashing this week!

I'm working on a project in the Sahara and they have alot of issues with dust and sand and vibration proofing their equipment.

Have you or any of your customers resin encapsulated a PLC board?  I was thinking of going upto the base of the IC holders so any IC's could be replaced, anything else would be PLC write-off?

Do you think heat dissipation would a problem?  Other than the main CPU and maybe the PSU regulators are there any other parts that generate excessive heat?

Many Thanks
