Connect Climatix control unit to Ethernet (Modbus TCP) using a standard network
cable.
Proceed as follows to configure the unit for internal Modbus TCP:
Step
Action
1
Log into the hand-held unit using password 2000.
2
Select
Main menu
>
System summary
>
Communication
>
Modbus
>
-
Internal Modbus
:
Decide whether the integrated Modbus interface RS485 is to be used as
Master or Slave. This does not affect Modbus TCP.
3
Select
Internal slave address
:
Set the correct Modbus slave address (1…247).
Warning!
This also applies to Modbus RTU.
4
Select
Internal settings
for
TCP/IP
>
NB:
Settings for TCP/IP can also be viewed - and changed here:
Main menu
>
System summary
>
Communication
>
TCP/IP
>
-
Make sure that you change the TCP/IP settings if the control unit is
already connected to the Ethernet for any other purpose.
5
Select
DHCP
(normally Passive):
Active, DHCP server issues addresses.
Passive, IP address is fixed.
6
Select
Set IP
:
Specify the control unit’s IP address if DHCP is set at Passive.
7
Select
Set Mask
:
Specify subnet mask if DHCP is set at Passive.
8
Select
Set Gateway
:
Specify the control unit’s gateway address if DHCP is set at Passive.
9
Select
Restart
:
Use this command to restart the control unit when you have finished.
After restart, internal Modbus TCP is configured and ready for use.
The general rule is that the control unit must be restarted using “Restart” or by
switching the power to the unit off and on after changes in order that the new
settings will apply.
Settings other than the above have nothing to do with Modbus RTU in slave
operation and should not be changed.
