In order to configure the 750-655 AS-i module and to assign the slave device IDs you need to use the WAGO I/O Check software (759-302). Connect the WAGO programming cable (750-920) to the bus coupler and to a free serial port on your computer.

It may be helpful to assign variable names to each bit that indicate the AS-i ID and bit number. In this example the input Flag bits are also given names. 9/13/2007 Using the WAGO 750-655 AS-i Module with the SMLC...

If you intend to use Analog I/O it is necessary to use the WAGO ASInterface CoDeSys library (ASInterface_01.lib), which is available for download on the WAGO web site. Application notes on using this library are also available on the WAGO web site.
