Node 51 (AC800M) is not visible on Network RNRP list
During my daily check on system I noticed that all my AC800M controllers are visible on RNRP list apart from Node 51. We used Node 51 only for Serial Link signals from 3rd part equipments on our asset. I have done on investigation on this matter and used RNRP Fault Tracer tool for monitoring and found this message:
** Incorrect Subnet Mask for 172.16.68.151 (IP Address of Node 51)
Just for info: IP Subnet mask: 255.255.252.0 (default)
I have done the comparsion between Node 51 and Node 52 (which is visible on RNRP) and identified with the same settings.
You recommendation would be helpful to sort out this issue.
Is this a new problem with this controller, or has it never been active on RNRP?
I've never seen the "Incorrect subnetwork mask" without a reason.
Where did you check existing network settings? Control Builder project? Can it be so that the controller *is* running 255.255.255.0 but has been downloaded with 255.255.252.0 and is since waiting for a controller reset (which is required when changing IP-setting)?
Try checking the controller log - if there has been little output you may be able to see the *current* IP-settings which is written to the log when controller has started, perhaps it is running with 255.255.255.0 - if so, schedule a controller reset when process conditions permit.
Yes, Sir, it has recently happend and noticed just a week ago. Before it was on the list.
Yes, I have checked the controller settings like the chain below:
** Controller>Hardware AC 800M>PM866>Ethernet
** Ethernet details: IP address: 172.16.68.151
IP Subnet mask: 255.255.252.0 and etc.
I got your point about IP config, dont know to be honest. Because I have also checked the controller log and found such an message from comissioning time:
