No communication BackupCPU error
I had setup a redundant PM865HI controller with no graphic aspect. All LED showing normal and the redundancy is working. but when I connect my laptop to control builder, this warning always show up:
"No communication BackupCPU"
Anyone can tell me how to get rid of it?
I have configured the IPconfig to set backup PLC with default rules.
I can ping both CPU at the same time (192.168.10.1- Primary, 192.168.12.1-Secondary)
Software:Control Builder M
CPU:PM865HI with SM811 (IP address 192.168.10.1, Subnet mask 255.255.0.0)
Is it due to the RNRP? How should I setting it?
Ensure while setting IP address standby controller should be turned off and both controllers should have same firmware.
Once IP address set through the ipconfig you reset the controller ensure CN1 cable is connected and now connect the secondary cable to cn2 and open CBM and set the IP address of the secondary and enable secondary connection and then reset the controller and ping the both IP address and now power on standby controller and connect both CN1 and CN2 cable
Since you are following class C IP address then ensure you have to explicit address in rnrp to make it work properly
