Dear all,

1) I have about 7 hvac controllers Siemens Power MEC 1201, 16DI, 4DO, 8AI, 4AO (part number 549-614)
2) controllers connected to BLN (2 wire) bus
3) BLN bus connect to PMD terminal of Siemens Trunk Interface II
4) Siemens Trunk Interface II connect to PC via rs-232
5) There is a Desigo Insight installed on PC
6) There is PII connection type at SCADA System Settings. This connection type assign to Trunk Interface

So, now i want replace old SCADA by newer. Also i want replace Trunk Interface II by more modern device. But i can't understand what is BLN interface/protocol, which privide Apogee Power MEC controller. What hardware should be instaled for integrade BLN to Bacnet IP, or ModBus (RTU, TCP) ect;

BR)

BLN means Backbone Link Node/Concentrator Node
Nortel Networks Backbone Node

Unfortunately Nortel Networks Inc. and certain of its U.S. affiliates are debtors in chapter 11 proceedings pending before the United States Bankruptcy Court for the District of Delaware.
