Step

Procedure

 

 

 

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.

 

 

 

2

You will need to set each controller’s IP address prior to network connection since every HC900

 

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

 

connection to the controller at the desired baud rate (see Direct Serial RS-232 Connection above).

 

This will require a null modem cable.

 

 

 

4

Select the Set Controller’s Network Parameters button. Using the wizard (bottom radio button), select

 

the PC COM port to be used, then set the controller’s new network parameters including IP address,

 

Subnet Mask, and Default Gateway (if required). See your IT network administrator for proper

 

entries. (Refer to the on-line help provided with the HC Designer software, 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.

 

 

 

5

Repeat step 4 for each controller on the same network.

 

 

 

6

Select the Network button at the bottom of the dialog box and Add any or all of controller IP

 

addresses configured to the list. This will allow selection of any of these Addresses for downloading

 

or uploading configurations.

 

 

 

7

You may now connect the controllers to your network for access by the Hybrid Control Designer

 

software. For the Networking Example shown, connect one end of the Ethernet 10Base-T cable to

 

the PC’s network port. Connect the other end of the Ethernet 10Base-T cable to the Ethernet

 

hub/switch.

 

 

 

8

Connect an Ethernet 10Base-T cable to each HC900 controller’s Open Ethernet RJ-45 port (top RJ-

 

45 port). Connect the other end of each Ethernet 10Base-T cable to the Ethernet hub/switch.

 

 

9

You may now access any controller on the network for configuration access by assigning Network as

 

the Port and the respective IP Address as the Address of the controller.

 

 

ATTENTION: When multiple controllers are on the network, be careful to check for the correct

 

IP address of the destination controller prior to download of a new configuration or when

 

downloading edits to a configuration while in RUN mode. Otherwise, you may inadvertently

 

download a configuration to the wrong controller.
