# Source Network Address (SNA)

A channel will monitor (receive data from) this address on the industrial communications network to which it is connected, updating at the channel scan rate. The net address format is net/node/address (for example, 1*1*00001). The SNA determines what available choices are relevant for other items in this dialog box, so the SNA should be established before configuring other channel configuration items. If the SNA is changed, it will cause existing settings for the channel to be returned to factory default.
