Change Baud Rate on port

[JohnnyB]

Hi .

I use an V1040 with visilogic 9.4.0

Is possible change the baud rate (PORT1, PORT2, PORT3) without in Visilogic

Thanks all for attention

I'm pretty sure you can do this in INFO Mode on the PLC.

You can do it through info mode, correct. This is handy to make a quick change for testing and initial setup.

If the change is to be permanent, I prefer to do it via a COM_INIT block in the ladder program, using SB2. That way the com settings will always be confirmed at power up. The settings are then part of the project so they will be transferred if you load the program into a new PLC.

Friends

Thanks for replies. Is possible apply changes from INFO MODE in the COM_Init block ? - I can change same parameters on info mode, but, after PLC restart, the code stored on ladder load values write in the code. Is possible access these parameters on SI, SB or other mode to write on ladder ?

COM_INIT trumps info mode to the values loaded in the block. The only way you would be able to have changes would be to have multiple COM_INIT blocks. You could put a compare block in front of them tied to an MI which would select which COM_INIT was called on power up.

Fantastic Joe..

I am very grateful for his suggestion.

I create an DT for COMM setup... According to the configuration i enable an specific bit to load the corret COMM config on startup :-)

Many thanks for all.
