Hi,
modscan
modsim
libraries with 10001 or 30001
Can you tell us what this is ? Can you also post a (basic) VI with the serial ModBus comm.

ok i try to explain it a bit more. modscan and modsim are programs that i found which simulate modbus devices or simply scan an active modbus communication so that you can see whats going on. the values i mentioned (10001 and stuff) are those that are given to me by labview.if i start a new project with a modbus io server and create some variable bindings i always got those variables. with some of them i can send or gather data from modscan, with some others not!
actually my programs only consist of the variables i get when creating new bindings and for them i got element to show or to to write something to them

If you have no progam in Labview you can't have a problem in Labview
It still doesn't make sense to me what you are saying.
Ok, the Modsim part I understand (that was easy) If you use a Modscanner to monitor the serial port ?? then it is possible that a other program cannot get control to that port.
Please explain what you are trying to do in Labview

Did you try my vi in the MB.zip ??
Did you put it in a VI with a configure COM port ?? ( I don't think this was in this VI but I cannot check this at the moment, Don't have LV8 at home )
Can you post your VI, sometimes this clears up a lot of things.
Tomorrow morning (for me) I look further into it.
