Integration notes

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the ASCO 7000 Series Group 5 controller via BASgatewayLX and exports what it actually has to Excel — free.

Questions about the Contemporary Controls ASCO 7000 Series Group 5 controller via BASgatewayLX

How many BACnet points does the Contemporary Controls ASCO 7000 Series Group 5 controller via BASgatewayLX have?

This list has 89 BACnet objects: 38 analog inputs, 51 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls ASCO 7000 Series Group 5 controller via BASgatewayLX BACnet points are writable?

None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.

Where is the official Contemporary Controls ASCO 7000 Series Group 5 controller via BASgatewayLX BACnet documentation?

The source is BASgatewayLX Modbus device profile Asco_Group_5_Controller_a (Asco_Group_5_Controller_a_LX.csv), published free by Contemporary Controls at https://www.ccontrols.com/support/dp/Asco%207000%20Group%205%20controller.zip.

What are the minimum BACnet points to integrate the Contemporary Controls ASCO 7000 Series Group 5 controller via BASgatewayLX?

Start with BI 4 Main on Normal (Main contacts on normal); BI 5 Main on Emergency (Main contacts on emergency); BI 8 Normal Source Available (Normal source available); BI 9 Emergency Source Available (Emergency source available); BI 51 Engine running (Engine running); AI 17 Normal Voltage Phase AB (Normal voltage A-B); AI 21 Emergency Voltage Phase AB (Emergency voltage A-B); AI 54 Control Panel State (Controller state); BI 46 Transfer Switch Locked Out (Transfer switch locked out).

How do I check these points on the real ASCO 7000 Series Group 5 controller via BASgatewayLX?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
