The Modbus library is a free, downloadable set of Virtual Instrument (VI) function blocks that provide Modbus communication from any standard Ethernet or serial port. The LabVIEW library implements the Modbus protocol in software and offers both master and slave functionality. Using the Modbus library, Programmable Automation Controllers (PACs) can communicate with gateway devices that provide connectivity to a wide variety of industial networks, such as Profibus, EthernetIP, and DeviceNet.

Why an .msi, not .llb?!
No use to us original (Mac) LabVIEW users; what am I supposed to do with a Windows installer?! Isn't LV still a cross platform language, born on the Mac?

Error in code
The "MB Modbus Command to Data Unit.vi" has a mistake in it. The "Write Multiple Coils" Function Code will not work properly past 8 bits of data. In case "15", the index to the "Split Array" VI should just be 8. Either that or you could remove the shift register and use an index array instead. The current implementation however corrupts the output data past 8 bits.
