Posted 1 Jun 2007 I have successfully setup a QJ71MB91 Modbus module to talk to several VFD's. My question is can I setup a second 'MB91 module on my rack as a second Modbus master? I want to have 2 seperate Modbus networks, one for my VFD's and one for various instrumentation in my application. Thanks. Share this post Link to post Share on other sites
Posted 3 Jun 2007 No limit on the number of these modules you can have in the system, so yes. Share this post Link to post Share on other sites
