potable applications
Introduction
AquaMaster 3TM is a range of high performance
electromagnetic flowmeters for the measurement of
electrically-conductive fluids and is normally supplied as
factory-configured, calibrated systems.
This MODBUS tables supplement contains MODBUS
Protocol implementation information and MODBUS
Protocol Register Allocation tables and is applicable to
product firmware version WAJC2103 v01.00.00 or

Detailed specifications and recommendations for using
and implementing MODBUS communications are
contained in the following external publications:
– MODBUS Over Serial Line – Specification and
Implementation Guide V1.02. Dec 20, 2006.
http://www.modbus.org/.
– MODBUS Application Protocol Specification V1.1b.
Dec 28, 2006. http://www.modbus.org/.
This supplement should be used in conjunction with the
following publications:
– Programming Guide (COI/FET2XX–EN)
– User Guide (OI/FET2XX–EN)

MODBUS Protocol
1 MODBUS Protocol
AquaMaster 3 RS485 MODBUS option implements the MODBUS over Serial Line protocol described in
the following MODBUS publications:
MODBUS Over Serial Line –Specification and Implementation Guide V1.02. Dec 20, 2006.
MODBUS Application Protocol Specification V1.1b. Dec 28, 2006.
Section 1.1 provides specific AquaMaster 3 MODBUS implementation details and section 1.2 provides
an overview of the AquaMaster 3 MODBUS Register mapping.
1.1 Implementation Information
The following information should be considered when implementing a MODBUS master to communicate
with AquaMaster 3:
Transmission mode: Remote Terminal Unit (RTU) slave.
Response time-out: 1s
Turnaround delay: 800ms
Interface power-up considerations.
The AquaMaster 3 MODBUS interface has been designed for low power consumption so that it can
be used with battery or renewable energy supplies (as well as with mains power).
When the AquaMaster 3 MODBUS interface is inactive (no characters received for 10s) it is switched
into a low power state. In this low power state it is not possible for AquaMaster 3 to receive the first
characters sent to it although the interface will be 'woken up' within 1s by communications activity.
Therefore, after any period of inactivity longer than 10s it is necessary for a MODBUS master to
perform 1 retry to communicate with AquaMaster 3s.

MODBUS Protocol
1.2 AquaMaster 3 MODBUS Register Mapping
The AquaMaster 3 MODBUS interface provides access to AquaMaster 3 parameters described in the
AquaMaster 3 Programming Guide (part no. COI/AQUAMASTER3-EN).
In general, AquaMaster 3 parameters with security access levels 0 to 7 can be read via MODBUS and,
where defined, parameters with security access levels 0 to 4 can be written via MODBUS.
Writeable parameters identified as MID parameters (see Appendix A) become Read Only via MODBUS if
the AquaMaster 3 flow meter has been configured for use as an MID instrument –refer to the
AquaMaster 3 Programming Guide (COI/AQUAMASTER3-EN) for details. Attempting to write to MID
parameters in an MID instrument results in MODBUS exception code 04, Slave Device Failure.
Table 2.1 shows the mapping of AquaMaster 3 MODBUS Registers to MODBUS Function Codes and
AquaMaster 3 data types, section 1.3 provides details of usage for each Register Address Range and
Appendix A provides the Register allocation tables.

1.3 Register Usage
This section provides further information and worked examples of MODBUS protocol messages,
application data units (ADUs) and their responses for each of the Register ranges corresponding to
AquaMaster 3 data types.
Note: MODBUS data model register addressing starts from XXXX1 but within the MODBUS protocol
data unit (PDU) addressing starts from XXXX0.
Register addresses shown in the Register allocation tables (Appendix A) are MODBUS data model
register addresses.
