2.2.1 Basic configuration of the IP address
The address selection switch on the I/O extension box configures the host part of the IP ad-
dress, that is, the last of the four parts of the IP address. By default, the first three parts of
the address (also known as the network address) are set to 192.168.1. If the switch is set
to a value other than 0 (all switches set to Off) or 255 (all switches set to On), the I/O extension
box will use the host part of the IP address assigned by the switch.
Figure 2.2 Example
The setting above configures the I/O extension box to have a host ID of 3 corresponding to
the binary value “00000011” where switch 1 is bit 0 (LSB) and switch 8 is bit 7 (MSB). The
I/O box will then have an IP address of 192.168.1.3.
Advanced configuration of the IP address
If the network part of the IP address must be changed from the default 192.168.1 for the
I/O extension box, the internal web server of the I/O extension box can be used. For details
please refer to the manual delivered with the I/O extension box.
2.3 Setup of the I/O extension box in the SOPAS Single Device
application
The communication with the I/O extension box is configured using the Interfaces and I/O Settings
dialog from the InspectorPIM60 menu. Check the Digital I/O and I/O extension boxes in the Inter-
faces tab. The I/O extension box is disabled if EtherNet/IP is selected in the same tab.
Figure 2.3 I/O Extension Box setup
Communication mode
It is possible to adjust the way that the Inspector is communicating with the I/O extension
box. The settings are made in the I/O extension box setup tab in the Interfaces and I/O Settings
dialog from InspectorPIM60 menu. There are three modes available:
• Robust mode. This is the default communication mode, and it is the recommended one if
the Inspector is connected to the SOPAS Single Device application during operation.
• Fast mode. This mode allows the Inspector to operate at a higher frame rate but there is
a risk that some data in the communication with the I/O extension box is lost if there is
high load on the network. This mode shall not be used if the Inspector is connected to the
SOPAS Single Device application during operation.
• User mode. This is the advanced communication mode where it is possible to configure
the number of retries that the Inspector performs, and the timeout for each retry. The
timeout is the time (in milliseconds) that the Inspector is waiting for a reply from the I/O
extension box for a request to set outputs or read inputs.
