Hello, I don't know the reason for using the CP342-5, because you can use the CPU315-2DP and SFC14 and SFC15. What are the parameters 0967 and 0968? BTW: have you seen the following links: http://support.automation.siemens.com/WW/view/en/8894584 http://support.automation.siemens.com/WW/view/en/22078757 http://support.automation.siemens.com/WW/view/en/8894363 Hope this will help. Best regards, Wizard |

Hello, The green blinking ofthe led, means there is communication, but your control word is zero. Have you seen the following faq: http://support.automation.siemens.com/WW/view/en/18208090 Take a look at point 5 It's important what I/O adresses the MM4 use. At the moment you are reading and writing to I/O adress 0 and 12 bytes on. The send and receive array of DP-send and DP-receive begin always at I/O adress 0. Hope this will help Best regards, Wizard |

New question published by Jas Banssen is split to a separate thread with the subject Use the DP_SEND & DP_RECV without the CP342. Best regards |
