what type of variable? integer, real, chart, string?
what hardware installation you have?
ok.
so on robot side you have to declare signals which are normally read as integer. so you will have to use some coding. Example divine by 100.
With strings is little problem, because in KUKA robots, strings are only as char array. But it only means that you will need additional signals for coordination of reading a string. And algorithm for changing integer to char.
No, serial comms don't act like Fieldbus comms. Basically, through RS232, everything is sent as a string, and conversion to extract INTs, REALs, ect, has to be done after.
At kuka.skyefire.org there are two files, SERIAL.SRC and SERIAL.DAT, which contain some old serial-communications test code that I used long ago. As I recall, it was sending a command to a vision system as a string, ang received back a string which contained several values, character and numerical, separated by commas.
On a kRC2, you need to physically connect to COM3 using a null-modem cable.
No. Enabling and configuring COM3 through HW_INF.INI and SERIAL.INI will be necessary, however.
