Command for baud rate

Denis

Hi guys

Sorry if my question seem stupid but I need to know

If when I set baud rate for a device, if I have to do it only one time in my prgm or I have to set before each command

Hi Denis,

Just set it in the ONLINE event for the device and you'll be good to go.

Here is an example for a NEC MT-1075

DATA_EVENT [PROJ]
{
ONLINE:
{
SEND_COMMAND PROJ , "'SET BAUD 9600,N,8,1'"
}
}

Tanks guys!

It's very appreciate.

Its a good habit to set the baud rate using an ONLINE event, for in the event that you need to swap or upgrade masters at some point in the future you won't have to dig around for the correct baud rate for each of your devices... it happens automagically.

is this the correct way to set an even parity?

SEND_COMMAND DATA.DEVICE, 'SET BAUD 38400,EVEN,8,1 135 DISABLE'

Nope, not according to Software History. Try this:
SEND_COMMAND DATA.DEVICE, 'SET BAUD 38400,E,8,1 485 DISABLE'

as far as i know using any SET command makes a setting permanent. so in a way it only has to be done once, as it's written to the processor memory.

so, like veraview says, if the controller gets swapped/zapped, you would need to ensure the SET commands are run again. which is fine, that's what we are doing with these ONLINE examples.

the point i'm getting to is to use TSET instead of SET. T is temporary i suppose. do this for any online event, or whenever. and use it often.

because apparently TSET doesn't write to memory, which can only be done so many x thousand times with SET. not sure on x, someone might know.

so TSET is valid, but doesn't remain permanent. which is okay cos the program should setup the ports when it boots.

i've replaced all SETs with TSETs in my programs.
