Relais controlling through R232

[martin204]

hello,

I got a problem with Relais controlling through R232. I found this file in forum named'Relaiskarte_8Fach_RS232.llb'. When I try to open the file'Relaiskarte 8Fach RS232 Open-Close Channel.vi', there is a ctl file named"com1_12port.ctl" which could not be found. then the whole program does not funktion either.

it would be very nice if someone could help me out here.

best wishes.

Hello,

You should disconnect the problem control from its typedef.

How ?

1) Open the llb and click "ignore " when LabVIEW loader asks for the missing control.

2) When program is loaded press CTRL+L to get error/warning list window

3) In the Error List window double click on the typedef error message in the error window

4) You should see the missing control grayed out.

5) Right-mouse-click on the missing control and select 'disconnect typedef'

The VIs are now in a runable state.

Good luck.

Hi!

I wanted to control relays with the serial port and find it's very much easier with the parallel port... pin 2-9 are 0-5v ttl output and pin 18-25 are associated gnd. Use the "IO on port VI" with 0378-037F as @...

I hope that will help you.
