Advise for Heidenhain needed

[Oopee]

Hello all,

Well, no advise needed (for the moment ) with programming but with transferring programs to machine. I have two machines wihch both have Heidenhain controll. THe newer is with TNC426 and there I use TNCRemoNt and ethernet and it works well.
But.. the older with TNC355... For many years I have used an old laptop and a program called Mikron Data Transfer MDT.exe) to transfer programs
in and out. If the program was over 999 blocks, I could transfer it blocwise.
Before I buyed that laptop, I tried at least five different desktops with different setting and could not get them to "cooperate" with TNC355.
Now, the poor laptop is dead and I´ve bought a 200Mhz desktop-computer,which I have connected to that computer which I use to make programs with (Would LAN describe that?)
Now, the problem is that I cannot get the connection between TNC355 and that 200Mhz computer to work, not using MDT.exe or not with TNCRemoNT either (No,the cable is not the problem). I have tried every possible setting I could figure out but

The funny ( ) part comes here:
A fellow from Heidenhain Finland (I´m a Finn ) was here with his laptop and with his laptop the connection worked with no problems with both software, MDT and TNCRemoNT. We configured my desktop to use exactly same settings than his laptop and it did dot work!

The question is: What difference and where could cauce this? Would it be some setting somewhere, or could it be some difference with the way the COM-ports are constructed/configured?

I know I could buy anothr laptop and get that networked with my other computers or just use a linking cable between that 200Mhz and laptop,
but I feel that it would be more comfortable to use that desktop.( I´ve bought a sealed "cabinet" to protect that desktop agenst dust, so I wouldn´t want to use it jus for a laptop, it woul be halfempty that way )

Looks Like Problem with COM Port.
Please swap it. Com1 to Com2 or Com2 to Com1.

I've had personal experience with old laptops that have the com ports wired differently than desktop computers. Pins 2 and 3 were reversed. Perhaps this was done at one time, so that users could use a regular serial cable to coordinate their laptop with their desktop.

You can try this out by purchasing a null modem cable, and a regular cable. One of these cables will make it work, if this is the problem.

The laptop which we used with the Heidenhain "guru" was only 1-2 yrs old and the cable we used was made following the instructions from TNCRemoNT CD/help. Maybe different cable wireing is
needed for desktops though,even they (at Heidenhain) claim that it is not. I´ll try your suggestion anyway.

Thank you,

Have you tried using another Com port. It could be that your com port is defective.

Mouldmaker,
Yes I have, I´ve tried that too
Thank you,

This one 1 is something different, we have a HEIDENHAIN TNC207 and we want to connect to a pc through TNCremoNT but I have not connected it through a com port but rather to a network with a MOXA NPORT Express. You see I have connected the TNC to an RS-232(serial port) then to a network cable to a pc.
how can I make the TNCremoNT recognize the TNC through the network. so far I'm trying to figure out how i can set up a com port to an ip address of the MOXA NPORT Express(it is a device that converts an RS232 serial port to a network cable). but having no luck.

Connection Configuration for my file transfer
:
TNC207----[RS232 connection]----MOXA NPORT Express----[network cable]----PC

whereas you connected:
TNC--------------[RS232 connection]-------PC (with TNCremoNT)

please how do i allow the software to recognise this???? pls e-mail at junsenario@gmail.com for suggestions

Thanks in advance

Jun,

We have exactly the same setup but with a TNC 155b control.

The control is connected to the network through a Moxa Nport express and the pc connects through the network to this device. It must have a fixed IP address which should be setup at the PC. Just install the software that came with the device. You should also have a fixed IP address for the PC.

But before doing this, you should first setup the control directly through the serial port to the PC. Check what the cable connection should be and test it out to see that it functions properly. Setting up the device should be done afterwards. You can e-mail heidenhain if you have problems with the cable connection. They will normally answer any queries the following day.

can u give me the heidenhain e-mail address to ask for my query

[Jun]

hey i have connected the controls to the pc directly via the RS232 connection but when I connect it to the MOXA it doesnt seem to communicate. i have fixed an ip address already and mapped that to COM4. I have a fixed ip address for my pc. So what should i do??

can u write up the procedures u took to communicate with the control thru MOXA nport express.

thanks in advance

Jun, please check your private messages to check on Local represanative of Heidenhain in Australia. Yuo can also contact Heidenhain directly on info@heidenhain.de

When you connected the control directly to PC, did this communicate properly? What software are you using for the data tranmission?
We are using TNC server for the data transmission. The programms are stored on the PC hard disk and they are requested directly from control without any input being done on the PC. We also use it to transfer/ backup programms written at the control. The pogramms are sent from the control to the PC and these are stored automatically on the PC.
Is the Moxa port communicating properly with the PC? Are the leds on the Moxa port all lit? If you ping the moxa port from the PC, will it communicate?

hello again Mouldmaker

I've gotten a reply from HEIDENHAIN but with no luck, they seem to not understand that my connection is still through the RS232 serial connection even though is through the MOXA NPort Express(model: DE-211) device server. I am using TNCremoNT ver2.3.255 with the TNCserver included in the 'Extra' tab as software for data transmission.

I am exactly trying to establish the same connection as with your situation with the TNCserver to a TNC407. I have used ping to test for connection and the communication with the MOXA and pc was proven successful. And also when the control (TNC 407 and TNC415) is connected directly to the PC both communicated properly.

All the LEDS on the MOXA port all lit except for 'Serial Tx' and 'Serial Rx'. I Know they should be able to light up but I'm not sure if its faulty.

If you might want to know I have set the jumper (labelled as SW1/SW2/SW3/SW4) to on-off-off-off to define a serial connection. Is that right? Or do I set this to an off-off-off-off for a data communication???

Kind Regards,
Jun
