3.2 Assigning the IP address for the controller/
BootP server
By default upon delivery, the Inline Controller has no preset IP address. Initial setting of the
IP address can be carried out with the PC WorX/PC WorX Express software manually via
the serial interface or by means of a BootP server. The IP address can be changed later via
the serial connection or Ethernet using the PC WorX/PC WorX Express software.
Bootstrap protocol
(BootP)
In an Ethernet network, BootP is used to assign an IP address to a BootP client using a
BootP server. For this example (default upon delivery for ILC 150 ETH), the ILC 150 ETH
(BootP client) sends a Boot_Request as a broadcast in the network. The MAC address of
the transmitter is sent with the Boot_Request to provide unique identification.
If the BootP server has been activated in PC WorX Express, PC WorX Express responds
with a Boot_Reply. PC WorX Express uses this Boot_Reply to inform the ILC 150 ETH of its
IP address and subnet mask. Please ensure that:
– The BootP server knows the MAC address sent by the BootP client
– A corresponding IP address and subnet mask have been assigned in
PC WorX Express for the MAC address
Once the IP data has been transferred to the ILC 150 ETH successfully, PC WorX Express
sends a corresponding acknowledgment message.
PC/network adapter To determine whether your network permits the IP settings used in the example project
(see Figure 3-3 on page 3-4), proceed as follows:
• In the Windows Control Panel, check the settings for your PC network adapter.
• If necessary, adjust these settings so that the ILC 150 ETH can be accessed in your
network using the IP address used in the example project.
If your network does not permit the use of the IP address used in the example project, adjust
the settings in the project information accordingly (see Figure 3-3 on page 3-4).
The procedure for assigning the IP address is essentially the same in PC WorX and
PC WorX Express for all Inline Controllers described in this manual. The following
example describes the setting in PC WorX Express for the ILC 150 ETH.
The connecting cable (V.24 (RS-232) cable) PRG CAB MINI DIN (Order No. 2730611) is
available as an optional accessory for connecting the controller to a PC via the serial
interface.
If any modifications are made to the project information that affect the IP settings for the
controller, a warning is displayed. However, the modification is not implemented
automatically. When a new project is created, the default settings are specified under
"IP Settings" (see Figure 3-3 on page 3-4).
