RNRP setting for access CBM from Client Server Network to Control network.
I use 800xA Ver 6.0.
I've installed Eng. stations which are working on Client Server Network only.
Eng. Station with CBM connected just to Client/Server network which is separated from Control network.
to be able to use CB i've enabled TCP/IP Forwarding parameter on Connectivity Servers and restarted them.
But Eng. station still can't go on-line with CB project, no comunication with controller. And Controller didn't show in Eng. Station RNRP.
Client Server Network is using adressing 172.16.4.x addressing.
Control Network Runs on 172.16.80.x addressing.
I didn't change any configuration in RNRP network.
1- Is it necessery Rnrp is configured with 'Explicity'?
2- Is it mandatory to Refresh Hosts file in RNRP Wizard? if Yes in what station?
3- What else needs to be done to access PLC in Control Network from CBM in Client/Server network?
What is the subnetwork mask?
The suggested IP-addresses support implicit addressing mode (which is recommended for its simplicity over explicit mode) but only if using a /22 (255.255.252.0) subnetwork mask.
Does the RNRP Monitor in the connectivity servers see the AC 800M CPUs?
If not, there is some trouble with the AC 800M settings (eg wrong mask or other setting, eg explicit setting made inadvertently on Ethernet 1/2, eg declaration of RNRP Area when that field should be left empty in implicit configurations - to use implicit mode you must only declare IP address and subnetwork mask - leave remaining fields at default except for Enable Interface on Ethernet 2 in case you run redundant control network). Remember, a controller reset is required after IP/mask change.
If the CPUs never been edited in CBM, use the IPConfig tool of CBM (and a serial cable) to ensure that the AC 800M's IP-addresses and subnetwork masks are OK.
If all settings look OK you should verify that the network switches have IGMP disabled. For example Cisco and Westermo both have IGMP enabled in factory default settings which need to be changed to comply with RNRP requirements.
Answers to your questions:
1. No, not with 172.16.4.0/22 and 172.16.80.0/22
2. hosts file not used with AC 800M, but a refresh can be in order in case IP-addresses has changed. The tool support "global" refresh of all reachable nodes.
3. Check IGMP. Firewall should be taken care of by the System Installer. I've seen issues when firewall service has been stopped/disabled - I suggest having it on/enabled.
