Posted 27 Dec 2017 Hello, For my assignment, I need to control lights from 2 seperate locations. I have two FX3GE-24M plc's connected through a LAN network. The idea is that when input X004 gets high, relays Y000 to Y004 gets disabled. I'm trying to use the Fixed Buffer communication protocol. Master IP address: 192.168.1.80 Slave IP address: 192.168.1.81 I'm using GX Works2 together with the FX configurator I'm lost in all the different datasheets... Could someone point me to the direction on what settings i need to change using fx configurator and a basic program of communication? Thanks in advance, Dennis Share this post Link to post Share on other sites
Posted 27 Dec 2017 (edited) Impossible Fixed buffer comm is only possible with the Enet module. There is a FB for MC protocol but than you still need at least one Enet module. Have you contacted Mitsubishi support on this? Have you got an HMI connected to the PLC's? Edited 27 Dec 2017 by Gambit Share this post Link to post Share on other sites
