Commissioning internal Modbus TCP

The illustration shows the devices and connections involved in commissioning:
24...230V~ 24...230V~ PB RS 485

Ethernet
Connect Climatix controller to Ethernet (Modbus TCP) using an ordinary network cable.
Proceed as follows to configure the controller for internal Modbus TCP:
Stage Action
1 Log onto HMI by entering the password 2000.
2
Select Main menu > System overview > Communication > Modbus >
- Internal Modbus:
Determine whether the integrated Modbus interface RS485 will be used
as a Master or Slave. This will not affect the Modbus TCP.
3
Select Internal slave address:
Enter the correct Modbus slave address (1...247).
Warning!
This also applies to the RTU.
4 Select Internal settings for TCP/IP >
Caution!
Settings for TCP/IP can also be viewed - and changed here:
Main menu > System overview > Communication > TCP/IP >
- Make sure that you change the TCP/IP setting if the controller is already
connected to Ethernet for some other purpose.
5 Select DHCP (normally Passive):
Active, the DHCP server distributes addresses.
Passive, the IP address is fixed.
6 Select Set IP:
Enter the controller's IP address if the DHCP is set to Passive.
7 Select Set Mask:
Enter the subnet-mask if the DHCP is set to Passive.
8
Select Set Gateway:
Enter the controller's gateway address if the DHCP is set to Passive.
9 Select Restart:
Use this command for restarting the controller when you have finished.
After restarting, the internal Modbus TCP will be configured and ready to be used.
Generally speaking, the controller must always be restarted using "Restart" or by
switching the power supply to the unit off and on after making changes in order for
the new settings to be valid.
Settings other than those described above have nothing to do with a Modbus TCP
operated as a slave and should therefore not be changed.
