Hello yanneschan.hk,the SIMATIC MODBUS/ TCP PN-CPU software package can be used for implementing Modbus/ TCP communication for S7-300/400. With it you can realize Modbus Client/ Server with functioncodes 1-6, 15,16. This software package is liable for costs (function block will be licensed per CPU). The wizard you mentioned is only for easy configuration the Modbus communication with this software. Because the communication is realized over the internal PN Port the connection and comm. has to be done with the so called 'T-blocks' in your program and not via Netpro which is used for CPs. So you normally have to define pointers, DBs, Areas, IP-Address and other (awful) things in HEX when you're using this 'T-blocks'. To save the trouble for our customer we created the wizard. Just have a look at our sample projects, play around with it, then you can get a feeling about it. Info: The Modbus blocks are fully functional even the blocks are not licensed, except the Status display and error LED flashing.
