BBMD configuration on M172P

[sardila]

Hi, 

I am currently implementing BACnet IP and BACnet MS/TP on M172p PLC. I couldn't find any documentation in regards BBMD configuration. 

At the moment I am using sysBACnet_BBMD block but it seems not working at all. 

Any ideas?? 

Thanks in advance

Hi,

from M172 PICS: Device support registration as a foreign device

you can test doing something like that:

(* BBMD Service *)
(* IP 0.0.0.0 ==> BBMD disabled *)
xRet := sysBACnet_BBMD(BBMD_Ip1,BBMD_Ip2,BBMD_Ip3,BBMD_Ip4,BBMD_port,BBMD_tmo);

I suggest to check with a wireshark log.

Note that Bacnet IP and MS/TP can't be active at the same time.

Hi,

Thanks for your reply. I have implemented the block with the Ip address. Anything else is needed to configure BBMD ??

I am testing at the moment using YABE tool, but I don't have any BBMD device to test. I have a wireshark sniffer activated but obveously I cannot see any traffic through BBMD IP. 

I am using BACnet IP / YABE to test connectivity and everything is fine, however, I am not sure if my BBMD configuration is enough to establish connection between M172P and BBMD device due to lack of documentation.
