Hello sandoz, Have you seen the following faq: http://support.automation.siemens.com/WW/view/en/9260793 Par. 3.5.1 tells something about number of slaves. You don't have to buy a dongle, you order the right module. Hope this will help. Best regards, Wizard |

Hi sandoz, When you use RS232, it will be a point to point communication. So this means just 1 slave! http://support.automation.siemens.com/WW/view/en/9127658 When you use RS485 it's a multidrop communication. Best regards, Wizard |
