Technical support / Flame treatment and T100MD1616
« on: March 23, 2013, 04:27:41 PM »
Hi,

I have a gas burner that has Automatic Ignition and Flame Monitoring Control Module.
Basically at every start-up a spark is generated until the flame is generated.

The problem is that the T100 get affected by the spark.(PLC reboots and/or the programs gets corrupted. ) Power is Ok, no variation in voltage.

The PLC is in a separated electrical panel (grounded) no inputs or outputs connected. Every time a spark get generated, I can see the outputs LEDs blinking, and the PLC stops working.

I power up the PLC form a different power circuit, same results.

Any suggestions ?

Thank you,

Dan

Technical support / Hex format outcomm/print
« on: March 13, 2011, 09:06:19 PM »
Hi

I need to communicate with a device that needs to receive a Hex format no.

Using T100 with a Outcomm 1,&HA3 I get  F8 00 F8
instead A3.(I'm sending this from T100 to a receiving PC)

Using a PC  to send a Chr(&HA3) -visual basic- I receive a A3, and with the same PC I can control my device

Please let me know

Thank you,

Dan

No,

Both my laptops are on XP, and like I said I can't figure out why the old one works Ok and the new one when I try to monitor a PLC, in the best scenario works for 1 min and then, the loosing connection message pops up.

I welcome any suggestion,

Thank you,

Dan

Hi,

I know this is not a software problem, but maybe you have a solution.

Recently I got a new Laptop (XP) and now I have problem when in
"monitoring." The connection drops all the time.

With the old laptop(XP) there are no issues at all.

Any sugestions?

Hi,

What about a pager?
I believe that I can I use T100Md connected to a modem, to call a pager and send a message to it.

Any samples codes?  Any suggestions?

Thank you,

Technical support / PLC Modem
« on: March 19, 2008, 07:39:05 AM »
Hi,

I have a new application were I will have a T100-Md monitoring the system. In the event of an error I need to send a SMS from a land line to a cell.

Any suggestions for a modem?

I would like to have several messages and phone no in the PLC and based on the event, send the appropriate string to the modem.

Thank you,

Hi,

1. does T100 have a "build in" WDogTimer?
2. if yes can it be turn off ?
3. aprox after how many loops (or milisec) the WDT resets the PLC

Thanks

Technical support / PLC resets
« on: July 23, 2007, 06:22:32 PM »
Hi,

I realize that this is software problem, but looks like I can't see the forest from the trees.

I have several "While" and "If" loops correlated whit communication with the COMM2. There is only one section of the program that I believe that resets the PLC (I'm loosing all data in variable and DM)
If I don't access that part of the programs (inputs are not activating  the custom function) everything is Ok.

What are the possible reasons (software only) for the PLC to reset?

Thank you,

Dan

Hi,

What will be the best way to de-bouncing 9 inputs on the T100.
I would like to do this thru programing and if is possible to be able to adjust it.

Thank you,

There is any host cmd that allows, with one cmd, to read all the variables (from A to Z)?

Thank you,

Hi,

I have one more question.

From your documentation: "Input$(n).....all the characters that make up the string will be removed from the COMM buffer."

This means that after Input$ the buffer is empty or I have to use the Incomm() to verify if the buffer is empty?

Technical support / RS232
« on: May 23, 2007, 07:31:40 AM »
Hi,

I have several devices connected to a T1616.
If I pool one device at a time it works Ok. If I do this in a sequence for 2 or more devices I got mixed results. Most probably is in the software but I just can't see it. I have a custFc that is activated every 1 sec.

DM[11]=0

If DM[11]=0 Then
Print #1 " cmd string "
A$=Input$ (1)
A$=MID$(A$,3,255)
A=Val(A$)
DM[11]=DM[11]+1
endif

If DM[11]=1 Then
Print #1 " cmd string "
B$=Input$ (1)
B$=MID$(B$,3,255)
B=Val(B$)
DM[11]=DM[11]+1
endif

Thanks
