System Configuration Example

1: Regarding Serial Nos. of high performance models

This FB is compatible with high performance models with Serial Nos. with the first 5 digits of 04012 or later.

2: Regarding the number of devices connected to an In-Sight Vision System

For using communication by FB and not using MC protocol: 8 devices or less (2 ports are used for sending and receiving

per device)

For using communication by FB using MC protocol: 5 devices or less (3 ports are used per device, for sending, for

receiving and for MC protocol)

3 QJ71E71-100 Q series sequencer Ethernet unit

4 Cognex In-Sight series In-Sight Vision System

Connecting multiple devices with In-Sight is possible using an

ethernet hub.2

5 PoE (Power over Ethernet) unit Power is supplied to the Cognex In-Sight series via an ethernet

cable.

Power can also be supplied using methods other than an ethernet

cable.

6 Ethernet hub 100BASE-TX
