When is an ENS-BAC-500, ENS-OPC-500, ENS-MON-500 or EMS-SMTP-500 license option required?


When is an "additional 500 points" license required for an Enterprise Network Server?


I/A Series G3 ENS-1 Enterprise Network Server


The basic Enterprise Network Server license does not include any external point driver licenses.  Driver licenses are required for each 500 or fraction thereof points of any of the four supported driver types.


An Enterprise Network Server can be licensed to directly communicate with BACnet, OPC, MODbus or SNMP points by the addition of the specific driver license option.  Each of these driver licenses support communication with up to 500 points of that specific type of points.

The four driver licenses are as follows:

  • ENS-BAC (BACnet IP or BACnet Ethernet)
  • ENS-OPC (OPC Client),
  • ENS-MOD (Modbus TCP)
  • ENS-SNMP (Simple Network Management Protocol). 

Each of these driver licenses will support the communications with up to 500 points of the specific type.  For each additional block of 500 points of a specific type, you need to purchase an additional points license, ENS-BAC-500, ENS-OPC-500, ENS-MOD-500 or ENS-SNMP-500. 

Here is an example of how these licenses are used.  The Enterprise Network Server needs to communicate directly with 1250 BACnet IP points and 60 SNMP points. 

The following licenses will be required:

  • ENS-1 -- Enterprise Network server license
  • ENS-SNMP -- allows ENS to communicate with the 60 SNMP points, technically allowing communications with 500 SNMP points.
  • ENS-BAC -- allows the ENS to communicate with 500 BACnetIP points
  • ENS-BAC-500 -- allows the ENS to communicate with an additional 500 BACnet points bringing the total to 1000 BACnet points
  • ENS-BAC-500 -- this second ENS-BAC-500 license will allow the ENS to communicate with the additional 250 BACnet points, actually bringing the total allowable BACnet point count to 1500 points
