Dear all, I have tried to download the example below to see how to set up a Modbus TCP client in S7-300 PN CPU https://support.industry.siemens.com/cs/ww/en/view/109745187 For ModbusPN block it has input 'start address' and 'length', I set up as '0200' and '4' For example holding register 40200 = "11" 40201 = "22" 40202 = "33" 40203 = "44" but where do I find these data in the block?? I assume the DB instance of ModbusPN FB contains it? could anyone give me some help.. Thanks, Jason |

New question published by Ella0216 is split to a separate thread with the subject Need to read holding register 0010-0019 (dec) and holding register 0040-0049 (dec). Best regards |
