6.1 Data from Modbus ® to the controller
The following function is provided for data transfer:
Modbus Function Code Designation
16 (10h) Write multiple registers
The following data can be sent:
Word address Word Designation
address
hexadecimal
decimal
0000h 0000d Actuate pump
(Only possible in
"Automatic"
mode!)
0001h 0001d Actuate valves
(Only possible in
"Automatic"
mode!)
0002h 0002d Pressure
specification for P0
0003h 0003d Switch over the
operating mode

Note!
Remote control via the Modbus master is only possible, if this has been
enabled in the touch controller,  5.4 "Access codes",  21 (Settings >
Service > Configuration (211)).
Addressing
Word address / register
address [decimal]
Bit addresses
Bit 0 = pump / compressor 1 ON
Bit 1 = pump / compressor 1 OFF
Bit 2 = pump / compressor 2 ON
Bit 3 = pump / compressor 2 OFF
The pump is only controlled by
the controller process if neither
the bit for switching on nor the
bit for switching off a pump is
set.
Bit 0 = make-up valve OPEN
Bit 1 = make-up valve CLOSED
Bit 2 = overflow valve 1 OPEN
• Servitec with 2x2W-KH: PV
open
Bit 3 = make-up overflow valve 1
CLOSED
• Servitec with 2x2W-KH: PV
closed
Bit 4 = overflow valve 2 OPEN
• Servimat: Spray tube
changeover
• Servitec with 2x2W-KH: CD
closed
Bit 5 = make-up overflow valve 2
CLOSED
• Servimat: Container
switchover
• Servitec with 2x2-W-KH: CD
open
Bit 6 = valve MKH 2 OPEN
(Servimat only)
Bit 7 = valve MKH 2 CLOSED
(Servimat only)
The valve is only controlled by
the controller process if neither
the bit for switching on nor the
bit for switching off a valve is set.
Pressure value for "P0" in
1/10 bar
If the value "=" is transferred
here, then the actual setting in
the controller is not changed.
Bit 0 = operating mode  STOP
Bit 1 = operating mode 
AUTOMATIC

6.2 Data from the controller to the Modbus ® (read operating data)
The following functions are provided for data retrieval
Modbus Function Designation
Code
2 Read discrete inputs
3 Read multiple registers (from
address 100h  # = 1)
4 Read input registers (from address
000h  # = 0)
