Hello luki; If you follow this link to the Product Support page for the PAC3100, you will find documents that will help you out in your project: http://support.automation.siemens.com/WW/view/en/33618253 The PAC3100 manual will show you that the units communicate over their RS-485 interface using Modbus RTU protocol. So whatever hardware/software you decide to use on your display PC must haveModbus RTUsupport and a RS485 interface. As a PLC programmer I would tend to use a small PLC supporting Modbus RTU as a master and data collector for the data from all your units, connected to your PC with either a small runtime HMI or some form of pocket SCADA to show all the values you would like to show. For example a S7-200 with an add-on Modbus library couls collect the data from all your PAC3100; you could use PC access OPC server to transfer these data to a runtime program to your choosing. on the PC, Hope this helps, Daniel Chartier |
