Dear Tabby, The null modem cable should be attached to IF1A interface of Panel. The cable should be used between PC and Panel. Perhaps this link might help: http://support.automation.siemens.com/WW/view/en/23787153 The cable between Panel and CPU is RS485, you can use Profibus cable. (Connect it to IF1B) Best regards, Wizard |
