Yes it is possible, but please give more details |
The more you know, The more you know that you don't know |

I think all has this capability. Not all has 4-20 mA, but all handles +-10V. |
Best regards, |

I got a CPU 222 S7-200, do I need an expansion module to output the signals or is there 0-10V/4-20mA outputs on my unit ? |

Hi, You need an expansion. Only CPU224XP has integrated analog inputs +-10V. |
Best regards, |

Who should I e-mail/phone in Norway about getting the cost of S7-200 CPU224XP or better, or the appropriate expansion modules ? |

This link got a ramp generator example: https://support.automation.siemens.com/WW/llisapi.dll/1853767?func=ll&objId=29980929&objAction=csView&nodeid0=10805384&lang=en&siteid=cseus&aktprim=0&extranet=standard&viewreg=WW&load=treecontent The problem is it is in Step 7... Is it possible to program this for S7-200 too, or would I need a S7-300+ ? |

It may be that I don't know what file to be looking at, but I can't find any file I can open in MicroWIN... |
