Hello Miffo; If you mean that the Rosemount unit can exchange data as a Modbus slave, then yes, the S7 PLCs can be fiitted with a serial processor (CP 341 or CP 441-2) and a Modbus master interface. Not cheap, but it can be done. Look at details of the Modbus master driver and components here: http://support.automation.siemens.com/WW/view/en/1220184 Another option, as most Rosemount units I know of allow for a HART interface, would be to use an ET 200M station (Profibus-DP slave interfaceIM 153-2 with S7-300 modules) with HART analog inputs and/or outputs. You can find information on this HART option here: http://support.automation.siemens.com/WW/view/en/22063748 Hope this helps, Daniel Chartier |
