Enable Signal and Modbus TCP IP
« on: April 19, 2010, 06:27:40 AM »
Hello,

I would like to use the enable signals 1-4 of Mach 3 for the controller enable of my positioning controllers. But not via the parallel interface, instead with a Wago module via TCP IP. Is it only possible to realize this with Brains or VB or is it also possible to use “Ports and Pins” with “Port 0”? If I realize this with Brains, which settings do I have to make under “Ports and Pins”?

currently, you can only talk to TCP modbus via Brains.

i.e. you will need to set up your TCP connection and varify it is working with the TCP modbus first.
(Read "Brains Users Guide") in the member support docs.

then once you have it set up,  below is  example rungs.(assumes, your tcp out is on cfg1, and your enables start
at your first address which equates to local var 0)

Enable1->noop->(Modbus TCP output, cfg1, local modbus var0)
Enable2->noop->(Modbus TCP output, cfg1, local modbus var1)
Enable3->noop->(Modbus TCP output, cfg1, local modbus var2)
Enable4->noop->(Modbus TCP output, cfg1, local modbus var3)
