The WP231 needs 16byte of in- and output space. As memory 3750bytes for the function block is needed and additional 990bytes for each WP231 data blocks. If you are using Modbus for communication you have to refer to the Modbus "Master" restrictions, on the WP231 side thereare nor restrictions, you just need to give eachr WP231 a unique address. See also the manual chapter 5. The manual you download here: http://support.automation.siemens.com/WW/view/en/64722267/133300 Regards ABenno
