communication between parrallel loops

[Henrik_Volkers]

implement ethernet connections in each loop 

next step: use a server on the other side of the internet just because 127.0.0.1 is much to easy

Great one Henrik..

One could also program two robots - one to write the data ona piece of paper, which is put into a cryptex (refer to Dan Brown's Da Vinci Code). This cryptex is transfered to the other robot (due to the fact that the data is in a cryptes you have it absolutely secure), which opens the cryptex to read the data again. To transfer the code of the cryptex, we could use the internet-method... :D:D:D:D:D

Ok - let's get serious again...

How about VISA write and read with a loopback connector on the serial port.

its hard to find PC nowadays with two rs232 ports,  (mine has only one) BUT using the DTR/RTS and the parallel port pins allow communication.... or

More hardware would be a USB hub with two USB/Rs232 converter and null modem cable. But you can hide all that in one USB-Loopback-box with a single connector

I liked that becktho... My unofficial ***** rating for this.

You can do the loopback test with a single serial port.

I really don't understand why you're all going these complicated ways. I think the simplest thing is just to let the user have 2 controls and just let them enter the data for each loop. This is even more versatile, because it can easily be used to have different data in each loop. Also, you won't need to hide the indicator because there will be 2 controls.

Debating with self...

OK, decided to be safe, so here it is -

Has anyone considered telepathy?

AKA "this damn program is going to do what I want it to do, not what I'm telling it to do!"

WoW..This has become a popular thread....Popular for the 'pun' ofcourse

Alternatively, you could use RFC1149 for the data transport. A working implementation is described HERE. 😄
