OVERVIEW
The Modbus® protocol was introduced by Modicon, Inc. for use in control environments featuring Modicon
programmable controllers. Due to its ease of use and implementation, this common PLC language was quickly
adopted as a de-facto standard for integration of a wide variety of master controllers and slave devices. Modbus
is a serial, asynchronous protocol. Transactions are half-duplex, featuring a single Master controlling one or more
Slaves. While RS232 can be used for point-to-point communication between a single Master and a single Slave,
a more common implementation features a multi-drop RS485 network with a single Master controlling multiple
Slaves. The AQUAVAR CPC features RS485 for its Modbus physical interface. In all cases, the AQUAVAR CPC will
act as a slave in the network.
RTU
The Modbus specification defines two distinct transmission modes: ASCII and RTU. The AQUAVAR CPC supports
RTU only.

WIRING
Physical wiring of the MODBUS communication cable is to the RS485 terminal block, 28, 29 and 30. Use the
screen connections if the cable has one.
NOTE: The only application macros that will work with Modbus communica-tions enabled are: [1] Single Pump,
[4] Constant Slv and [5] Speed Cntrl. See parameter 1102 Applic Macro. Multicontrol or Synchronous will not
work with MODBUS. Set macro to SINGLE PUMP, Constant Slv or Speed Cntrl.
Configure Modbus Serial Communications
1. Set EFB Station ID – This is the address of each Aquavar on the network. Each drive must have a unique
station ID on the network.
a. Go to Group 32 – EFB PROTOCOL, press SEL.
b. Go to parameter 3202 – EFB STATION ID, press EDIT.
c. Set desired station ID using the UP or DOWN arrows, press SAVE.
Valid addresses are 1 – 247.
NOTE: Address 0 is used to broadcast
messages to all slaves on the network.
NOTE: It is the user’s responsibility to ensure that reading and writing is done to the correct address
(Aquavar or node) in the network. Reading or writing to the wrong node can cause unexpected results.
2. Set EFB Baud Rate – The settings used must be the same on the Modbus Master and the slaves (Aquavar
CPC). Default rate is 9.6 kb/s.
a. Go to Group 32 – EFB PROTOCOL, press SEL.
b. Go to parameter 3203 – EFB BAUD RATE, press EDIT.
c. Set the desired Baud Rate using the UP or DOWN arrows, press SAVE.
Valid baud rates are:
1.2 kb/s 19.2 kb/s
2.4 kb/s 38.4 kb/s
4.8 kb/s 57.6 kb/s
9.6 kb/s 76.8 kb/s

WIRING
3. Set EFB Parity – The settings used must be the same on the Modbus Master and the slaves (Aquavar CPC).
Default parity is 8N2 (8 data bits, no parity, two stop bits).
a. Go to Group 32 – EFB PROTOCOL, press SEL.
b. Go to parameter 3204 – EFB PARITY, press EDIT.
c. Set the desired Parity using the UP or DOWN arrows, press SAVE.
Valid Parity settings are:
0 = 8N1 – 8 data bits, No parity, one stop bit.
1 = 8N2 – 8 data bits, No parity, two stop bits.
2 = 8E1 – 8 data bits, Even parity, one stop bit.
3 = 8O1 – 8 data bits, Odd parity, one stop bit.
4. Set EFB Ctrl Profile – The Aquavar Profile may be the only the only profile that can be selected.
a. Go to Group 32 – EFB PROTOCOL, press SEL.
b. Go to parameter 3205 – EFB CTRL PROFILE, press EDIT.
c. Set the desired profile using the UP or DOWN arrows, press SAVE.
Valid Profile settings are:
1 = AQUAVAR
Activate Modbus Communications on the Aquavar
1. Go to Group 30 – Options, press SEL.
2. Press Edit.
3. Using the UP or DOWN keys, select [1] STD MODBUS.
4. Press SAVE. Modbus Communications are now active.

SETTING DRIVE PARAMETERS
Note: With Modbus, any parameter can be accessed using the format: “4” followed by the parameter
number. See the following example:
Changing Ramps 1 and 2 via Modbus from 5 to 10 seconds on a drive over 15 HP.
1. Set parameter 1102 (Applic Macro) to: [1] Single Pump, [4] Constant Slv, or [5] Speed Cntrl.
2. Configure and Setup Modbus Serial Communications
3. Ramp 1 is parameter 1301 and Ramp 2 is parameter 1302.
4. Write ‘100’ to Holding Register 41301. Assuming no errors occur during this transaction, 1301 (Ramp 1)
should now be set to 10.0 seconds.
Note: There is an implied decimal point that is not written between the first (from the right) and second
digit. Thus 100 = 10.0
5. Write ‘100’ to Holding Register 41302. 1302 (Ramp 2) should now be set to 10.0 seconds.
START / STOP CONTROL
Start
1. Set parameter 1102 (Applic Macro) to: [1] Single Pump, [4] Constant Slv, or [5] Speed Cntrl.
2. Configure and Setup Modbus Serial Communications
3. Set parameter 1201 to [1] Fieldbus
4. To Start, write ‘1’ to Register 00002. Register 00001 (Stop) must be set ‘0’. The rotation arrow on the display
should now be spinning and the drive will start if the actual pressure is below the setpoint.
5. Write ‘0’ to Register 00002. The drive will continue to run as long as
Register 00001 is ‘0’.
Stop
1. To Stop, write ‘1’ to Register 00001. Register 00002, should be set to ‘0’. The rotation arrow on the display
should stop rotating.
REMOTE SETTING OF SET POINT 1
1. Set parameter 1102 (Applic Macro) to: [1] Single Pump, [4] Constant Slv, or [5] Speed Cntrl.
2. Configure and Setup Modbus Serial Communications.
3. Set parameter 1601 to [0] Setp1.
4. Set parameter 1602 to [2] Fieldbus.
5. Write a value between ‘10000’ and ‘0’ (100.00% to 0% of Transducer Max) to Holding Register 40003.
Note: There is an implied decimal point that is not written between the second (from the right) and third
digit. Thus, 10000 = 100.00%.
6
REMOTE SETTING OF SET POINT 1
For example, using the standard 300 PSI transducer supplied with the Aquavar CPC:
1. Parameter 1502 (Transducer Max) should be set to 300 PSI.
2. Parameter 1503 (Transducer Min) should be set to 0 PSI.
3. Setting to 60 PSI…
a. 60 PSI / 300 PSI = .2 or 20%
b. Write ‘2000’ to Holding Register 40003
4. Setting to 80 PSI…
a. 80 PSI / 300 PSI = ~.2667 or 26.67%
b. Write ’2667’ to Holding Register 40003
Speed Control through Modbus Interface
1. Set parameter 1102 (Applic Macro) to: [5] Speed Cntrl
2. Configure and Setup Modbus Serial Communications
3. Set parameter 1601 to [0] Setp1
4. Set parameter 1602 to [2] Fieldbus
5. Write a value between ‘10000’ and ‘0’ [100.00% to 0% of Maximum Freq (1401)] to Holding Register 40002.
Note: There is an implied decimal point that is not written between the second (from the right) and third
digit. Thus, 10000 = 100.00%.
For example, using a Maximum Freq of 60 Hz:
1. Parameter 1401 (Maximum Freq) should be set to 60Hz.
2. Parameter 1601 (SP1 / SP2 Select) should be set to 0psi.
3. Parameter 1602 (Set Point 1 Select) should be set to [2] Fieldbus
4. Setting to 60 Hz (Full Speed)…
a. 60 Hz / 60 Hz = 1 or 100%
b. Write ‘10000’ to Holding Register 40002.
Note: Writing to parameter 1403 will have no effect.
5. Setting to 30 Hz (Half Speed)…
a. 30 Hz / 60 Hz = .5 or 50%
b. Write ‘5000’ to Holding Register 40002.
Note: Writing to parameter 1403 will have no effect.
