Hi, I'm not an expert in Modbus, but the EM241 only works as a modem. So I expect that it can communicate but only vie telephone line. If you want to connect directly then: + have a look to Tip41 (secodn CD of Micro/WIN or Siemens Internet) + goto: http://support.automation.siemens.com/WW/view/de/27832511 + Modbus Slave simulation for PC, go to http://www.s7-200.net I hope this helps |
