BMS integration notes: SATEC EM133 power meter (ProtoNode profile)

Integration in brief

Read-only. Give the meter a Modbus Node-ID, add it in the ProtoNode web configurator, then map voltages, currents, total kW and PF, frequency and the energy registers.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Object	Name	Why	Access
AI 1	V1/V12 Voltage	V1/V12 voltage	Read
AI 4	I1 Current	Phase 1 current	Read
AI 34	Total kW	Total kW	Read
AI 37	Total PF	Total power factor	Read
AI 48	Frequency	Frequency	Read
AI 79	kWh import	kWh import	Read

Network setup

Set every meter on the ProtoNode's RS-485 port to Modbus RTU 9600 baud, 8 data bits, no parity, 1 stop bit, with a unique Node-ID (1-255).
Each meter on the ProtoNode is its own BACnet device: Device Instance = the meter's Modbus Node-ID + Node_Offset (default 50,000).
BACnet MS/TP: set the ProtoNode MAC address (1-127) on the A bank DIP switches and the baud rate on the B bank.
BACnet IP: set the ProtoNode IP address in its web GUI (FST Web GUI).

Watch out for

The devices on one FPC-N34 must not add up to more than 1500 Modbus registers (this profile uses 89).

SATEC EM133 power meter (ProtoNode profile) BACnet objects

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes

All objects are read-only analog inputs; the guide gives no units, scaling or Modbus registers for them (the Lon columns read TBD).
The same profile serves BACnet MS/TP, BACnet IP, Metasys N2 and LonWorks; the N2 point addresses match the BACnet instances.

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 EM133 power meter (ProtoNode profile) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the SATEC EM133 power meter (ProtoNode profile)

How many BACnet points does the SATEC EM133 power meter (ProtoNode profile) have?

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

Which SATEC EM133 power meter (ProtoNode profile) 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 SATEC EM133 power meter (ProtoNode profile) BACnet documentation?

The source is ProtoNode FPC-N34 and ProtoNode FPC-N35 Startup Guide For Interfacing Satec Products: BFM136 and EM133, revision Document Revision 1 (effective May 2014), published free by SATEC at https://satec-global.com.au/wp-content/uploads/2022/01/ProtoNode-Startup-Guide-for-Satec.Rev-1.pdf.

What are the minimum BACnet points to integrate the SATEC EM133 power meter (ProtoNode profile)?

Start with AI 1 V1/V12 Voltage (V1/V12 voltage); AI 4 I1 Current (Phase 1 current); AI 34 Total kW (Total kW); AI 37 Total PF (Total power factor); AI 48 Frequency (Frequency); AI 79 kWh import (kWh import).

How do I check these points on the real EM133 power meter (ProtoNode profile)?

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.
