MOD-Bus drivers

[max]

MOD-Bus is a simple protocol for serial communication, several controllers
(e.g. JUMO) work with this protocol.
I have to write a program for a teststand with some of those controllers.
Has anyone written some LV drivers which handle the MOD-Bus protocol (handle
address, checksum, error control,... ). Maybe there is even someonen who
hase written drivers for JUMO-controlers (dTron)?!

Yes there are several versions of Modbus drivers out there for LabVIEW. If you search the list archives for you should find several messages about it. Try the following link to get you started:
