DEIF AGC 150 Modbus register map
The DEIF AGC 150 is an advanced genset controller with a Modbus server. This map covers the GEN (genset) column of DEIF's AGC 150 Modbus server tables: generator voltage, current, power and energy, running hours and counters, engine communication values, alarm and mode bit words, control command words, remote command coils and status flags. The tables also cover BTB, mains, GEN-H, ENG and ATS controller types, and thousands of further addresses (power management, alarm strings, parameters by offset) that are not listed here.
- Protocol
- Modbus RTU (RS-485) and Modbus TCP
- Defaults
- RS-485 Modbus ID (parameters 7511 or 7521) range 1 to 247, default 3. RS-485 speed (7512 or 7522) 9600, 19200, 38400 or 115200 baud, default 9600. The TCP port and serial framing are not stated in the Modbus server user manual.
- Addresses in the manual
- 0-based protocol addresses, as sent on the wire
- 32 and 64-bit values
- High word first (AB CD)

- DEIF document 4189341212, AGC 150 Modbus server tables (Excel workbook), Revision Y, applicable to AGC 150 software version 1.38.0, DEIF A/S, vendor-hosted. Cited by sheet name and spreadsheet row number. Companion document: AGC 150 Modbus server User manual 4189341435-B EN, based on software version 1.37.
Address base. The tables print a Modbus address column and a separate PLC address column. Input register 500 has PLC address 300501 and holding register 0 has PLC address 400001, so the printed Modbus address is the zero-based protocol address and the PLC address is the five or six digit reference with a one-based offset. Addresses in this file are the Modbus address column. The user manual (section 4.2) lists the function codes per address area: holding 03/06/16, input 04, coils 01/05/15, discrete inputs 02. Address 500 in the manual is address 500 on the wire.
Word order. The user manual (section 3.4) states data format ABCD for 32-bit values, represented with HI16 on the lowest address and LO16 on the highest address. Values are scaled as actual value = register value times 10 to the power of minus scaling. The scale column in this file is the sheet scaling converted to a multiplier, for example scaling 2 becomes 0.01. Bit numbers in the bit words are as printed in the Bit column of the sheet.
Modbus Poll and the Modbus protocol itself count from 0. The "Wire address" column is the number to type into Modbus Poll.

Scale is the number to multiply the raw value by to get the unit. Types with more than one register (32 and 64-bit) follow the word order above.
Open in Modbus Poll
- Download the Modbus Poll blocks file.
- Open Modbus Poll, connect to the device and set its unit ID. In Modbus Poll set Word order to AB CD.
- In the blocks panel on the right, click Import CSV and pick the file. CSV import is a Pro feature. Without Pro, Modbus Poll polls the first 20 values of your blocks.
- The wire addresses are already in the file, so there is no 0-based or 1-based conversion to do.
Once the values look right, export the tag list to Ignition, Kepware, Node-RED, Home Assistant or Voltrus SCADA.
