I just thought I should let you know that there is still a bug in the transferring of a program when using the wireless
If you click on use turbo transfer mode the program will just hang up for ever and you must hit abort to reset then do the transfer without clicking on use turbo transfer mode.

You are correct in stating that Ethernet is becoming the most widely used interface on PLC'S nowadays.
Everyone is trying o find a low cost high speed and reliable 2 to 4 wire protocol to add external devices to a PLC
Like I mentioned earlier I never did use Mod-buss but I did use the Siemens Profi-buss many times as well as the Omron Hostlink on what they called industrial Ethernet which by the way worked quite well and was quite easy to set up in the PLC buy setting up how many words to send and how many to receive and the addresses of the words. I must include the I installed the units in what is clased as very noisy environment with very large VFD drives as well as gasoline engines running near by and everthing works great.  
So I guess I should look into using the Ethernet Port on the Super PLC.
However I am a little vague on how can I use the PLC as a master talking to a remote PLC as a slave and use the Web App at the same time when there is only one Ethernet Port.      
So I think my next project should be a master slave setup to use as remote I/O

Is there any way to connect to the PLC via Blue Tooth.
I have been asked by a couple of customers if there is such a think as a Blue Tooth connection and app for the Super PLC.

Again thanks for the expert help
I must admit in all the years I have been programming PLC'S I really never used a FOR loop as 90% of my programming was done in Ladder Logic and the rest was done using the built in functions supplied by the PLC manufacturer so I was a little confused on a couple of things.
If I wand to clear an area of DM'S then I would write
FOR N=7 to 22 meaning DM[7] to DM[22]
 DM[N] =0 // the DM tells the program that it is a DM area and the [N] is what is used for the variable and the =0                tells the program to set all the locations to a value of 0

Is the correct so far?

Then if I want to clear a group of relays say from relay 273 through 321 then I would write
FOR I = 18 to 20 //  this should be relay 273 to 289, and 290 to 305, and also 306 to 321
 RELAY = 0  // the RELAY tells the program that it is the Relay area and the is a variable and the =0 means the value to set all the relays to

So if I am correct then the letter after the FOR can be any variable letter from A to Z  then the start and end address the the area DM, RELAY etc. then the Value to put into the area. Is this correct.

You may help me to become half decent TBASIC programmer one day.

 

Is there a simple way to reset a large group of relays in TBasic?
The manual describes how to reset single bits 0 to 15
An example would be I need to reset relays 273 through to 310
From what I have learned so far I think it should be something like this.

DO I USE FOR N = 273 TO 310 // 273 to 310 are the individual relays but the channel number would be 35 to 39
OR DO I USE N = 35 TO 39 // // so this is where I am confused
RELAY[35] = 0

Would this be the correct way?

I am working with the FX2424 plc and I am wondering what is the simplest way to completely clear a plc back to the Factory Default condition. With other plc,s I have worked with it was as simple as creating a blank program with only an End statement With other Plc,s you also had to clear the retentitive memory area.

What sequence would you recommend to put a FX2424 back to the factory default.

While I was viewing all the resent posts I figured I should ask the one question that has been confusing me when it comes to the variables in the TRi PLC
You have A to Z, you have A# to Z# and you have A$ to Z$
I am confused about A to Z
If I understand correctly  A# to Z# are for storing floating point numbers
and A$ to Z$ are mainly for storing ASCII strings

Do they take up the same memory locations?
Can you use A to Z as well as A# to Z# and A$ to Z$ within the same program or would there be a conflict ?

Gary i guess I was in too much of a rush to test the program.
Once I took the time and studied what you had sent me I realized what I did wrong.
Your program works well.
Again thanks for your help
