Step
You may change the controller's IP address and related network parameters from its default using
7
the Utilities Worksheet in the HC Designer software. This may be done using either the RS-232 serial
port (legacy systems) via a null modem cable connection or the Ethernet connection from the PC to
the controller. If the RS-232 connection is desired, make sure the proper PC serial Com port to be
used has been set up (See Direct Serial RS-232 Connection page 133).
Select the Set Controller's Network Parameters button. Using the wizard (bottom radio button), select
8
the PC port to be used, then set the controller's new network parameters including IP address,
Subnet Mask (if other than the default), and Default Gateway IP address (if required, otherwise use
default). Refer to the HC900 Designer Software User's Guide or its respective online help, Utilities
Worksheet - Set Controller's Network Parameters, for further details on this step.
Note: This step will require the controller to be placed temporarily in the Program mode. After the
new network parameters have been downloaded, the controller will conduct a Cold Start in its
transition to RUN. This will cause an initialization if there is a current configuration in the controller.
D. Network Access to one or more controllers
ATTENTION:
Always observe the wiring/cabling guidelines on page 54.
Step
1 Make sure the PC has an Ethernet NIC (Network Interface Card) installed and enabled. Be sure the
NIC has an IP address (fixed or DHCP served) that allows access to controllers with IP addresses on
the same or other subnet. Consult your IT department or network administrator for allocating IP
addresses to the controllers if required.
You will need to set each controller's IP address prior to network connection since every HC900
2
controller is shipped with the default IP address of 192.168.1.254. Placing multiple controllers on the
same network before they have been given unique IP addresses will cause problems.
3 On the PC, use the Utilities Worksheet in the HC Designer software to set up the serial RS-232
(Legacy) or USB-RS485 connection to the controller at the desired baud rate (see Direct Serial RS-
232 Connection above). This will require a null modem cable.
