Schneider Electric PowerLogic ION9000

Compatibility

Compatible with EpiSensor Edge over Modbus TCP, Modbus RTU or BACnet/IP

Schneider documents the ION9000 as a Modbus server over Ethernet on port 502 and over RS-485 with Modbus RTU, with FC03 holding-register reads and the most significant word first. It publishes the fixed Modbus map with register numbers, sizes, data types, units and read-only permissions. BACnet/IP is available from firmware 4.6.0.

ION9000 and ION9000T commercial references METSEION92030 to METSEION95040, using the fixed map ION9000_Modbus_Map_004.005.000. The workbook does not state its address base: start with the register number minus one and check frequency at register 3110 against the display. Read-only monitoring: Modbus access stays Read Only and the External Control section is not written.

Interface

Documented measurements and integration boundaries for PowerLogic ION9000.

• The map gives register numbers in the same scheme as Schneider's PM5000 register lists, where register 3000 is zero-based address 2999 (Schneider FAQ FAQ000268374). The ION9000 workbook does not state its base, so start with address = register minus one and confirm with the frequency read in the worked check. The manual notes that ION9000 registers are numbered differently from earlier ION meters.
• The manual states that 32-bit values are sent most significant word first and each 16-bit word most significant byte first. Edge reads the map with FC03 Read Holding Registers.
• Current A, B and C at registers 3000, 3002 and 3004, neutral at 3006 and average at 3010: FLOAT32, two registers each, in A.
• Voltage A-B, B-C and C-A at 3020, 3022 and 3024 and the L-L average at 3026; A-N, B-N and C-N at 3028, 3030 and 3032 and the L-N average at 3036: FLOAT32 in V. Voltage 4-N is at 3096.
• Active power A, B and C at 3054, 3056 and 3058, total at 3060: FLOAT32 in W, not kW. Reactive power total at 3068 in VAR and apparent power total at 3076 in VA, with per-phase values in the three register pairs before each total.
• Power factor A, B, C and total at 3144, 3146, 3148 and 3150, displacement power factor total at 3158, and lagging and leading total PF at 3172 and 3174: FLOAT32. The meter's IEEE or IEC localisation setting decides the sign convention.
• Frequency at 3110: FLOAT32 in Hz.
• Active energy delivered (into the load) at 3204 and received (out of the load) at 3208: INT64, four registers, in Wh. Reactive energy delivered and received at 3220 and 3224 in VARh, apparent energy delivered at 3236 in VAh. FLOAT32 copies in kWh, kVARh and kVAh start at 2700 (delivered) and 2702 (received).
• Block demand, FLOAT32 in W: active power last demand at 29954 and predicted demand at 29956; delivered last and predicted demand at 29968 and 29970. Peak demand at 29958 is TIMESTAMPED_FLOAT32, six registers: the value, then a 4-register date and time.
• Power quality, FLOAT32: THD current A, B and C at 21300, 21302 and 21304; THD voltage A-N, B-N and C-N at 21330, 21332 and 21334; K-factor A at 21358; crest factor A at 21364; current and voltage unbalance worst at 3018 and 3052.
• Identity, UTF8: meter name at register 30 (20 registers), serial number at 117 (12 registers) and firmware version at 1717 (6 registers).
• Invalid reads: an unmapped register returns 0x8000, an unavailable FLOAT32 0xFFC00000 (NaN) and an unavailable INT64 0x8000000000000000. A read that splits a multi-register value returns exception 03. Record these as missing, not zero.
• The map marks measurements R/O. The External Control section at 52001 to 53000 is R/W (external pulse, external boolean and external numeric registers), and Modbus programming of setup is disabled from the factory. Keep the poll to R/O registers.

Setup

1. Identify the meter and its firmware

   Read the commercial reference on the label (METSEION92030 to METSEION95040) and the firmware version on the display or in ION Setup. The map used here is for firmware 004.005.000, and BACnet/IP needs 4.6.0 or later.

2. Choose the port

   Prefer Ethernet: Modbus TCP is enabled from the factory on port 502. For RS-485, set COM1 or COM4 to Modbus RTU with RS-485 bias OFF in ION Setup, the webpages or the display, and note the unit ID (100 on COM1 and 103 on COM4 from the factory), baud rate and parity.

3. Leave Modbus access read-only

   In ION Setup's Security wizard, Modbus Access is Read Only from the factory and configuration through Modbus programming is disabled. Keep both, and change the default password of 0 for USER1.

4. Read frequency to settle the address base

   Send FC03 for two registers at zero-based address 3109 (0x0C25), register 3110 minus one, and decode a FLOAT32 with the most significant word first. It must read near 50 or 60 Hz and agree with the display.

5. Add power and energy

   Read total active power at register 3060 (address 3059) in W and active energy delivered at 3204 (address 3203) as INT64 in Wh, then compare both with the display. Divide power by 1000 only where the destination wants kW.

6. Keep the poll read-only

   Leave the External Control registers at 52001 to 53000 and every R/W register out of the poll, and treat 0x8000, 0xFFC00000 and exception 03 as missing data.

Common questions

Is ION9000 active power in W or kW over Modbus?

In W. The ION9000 map gives Active Power Total at register 3060 as FLOAT32 in W, reactive power in VAR and apparent power in VA, and demand in W. Schneider's PM5300 list uses kW at the same register numbers, so do not copy a PM5300 template's scaling.²

Which Modbus TCP port and unit ID does the ION9000 use?

TCP port 502, enabled from the factory. The manual names unit identifier 255 as the meter itself when the Modbus gateway is in use, so use 255 over TCP. On RS-485 the factory unit IDs are 100 on COM1 and 103 on COM4.¹

Does the ION9000 send FLOAT32 values high word first?

Yes. The manual states that 32-bit data is transmitted most significant word first and least significant word second, and that each 16-bit word is sent most significant byte first.¹

Why does a register read return exception 03 or 0x8000?

Exception 03 means the read started inside a multi-register value, or the value is not allowed. An unmapped register returns 0x8000, and a reserved FLOAT32 returns 0xFFC00000 (NaN). Read each value from its first register and for its full length.¹

Can Edge read the ION9000 over BACnet/IP?

Yes, from firmware 4.6.0. BACnet/IP is disabled from the factory and uses UDP port 47808 once enabled with communication configuration access. Modbus TCP is enabled from the factory, so it needs no meter change.¹

Can I add my own registers to the ION9000 Modbus map?

Yes. The fixed map comes from the meter's Data Mapping modules, and ION Setup's Modbus Slave setup can add custom registers or replace the default map entirely. A site that has customised the map needs its own register list; this guide uses the default fixed map.^1, 2
