Hello JJaeger; If you mean an exchange of data between the 2 CPUs already set up as DP masters, then a DP/DP coupler would be appropriate, and easy to setup. Here is some informationon this module that allows 2 masters to exchange up to 244 bytes OUT and 244 bytes IN: DP/DP coupler manual: http://support.automation.siemens.com/WW/view/en/1179382 Sample configuration DP-DP coupler: http://support.automation.siemens.com/WW/view/en/22809787 Hope this helps, Daniel Chartier |

I would like to not add any hardware if possible. What if one my my CPUs was a slave and not a master. How would I transfer this data then? |

Ok - so I am using the following entry: https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&objId=19449428&objAction=csOpen&nodeid0=10805255&lang=en&siteid=csius&aktprim=0&extranet=standard&viewreg=WW I am a bit confused about entering the I/O data: Let's say my Slave system has data I want to transfer to the Master. In the Slave the data is I300.0-I300.7. Looking at the above entry, what do I enter in Figure 5? Then when I add the system in my Master, what do I enter in Figure 7? Do I need to define all I/O, or just the data I am interested in? The values that are shown in the Figures in the entry do not seem to match up at all. |
