SLC Passthru Communications
There are three types of communications passthru (or bridging) supported by
SLC 5/03, SLC 5/04 and SLC 5/05 processors.
• Remote I/O passthru via the 1747-SN and 1747-BSN remote I/O
scanner modules
• DeviceNet passthru via the 1747-SDN DeviceNet scanner module
• Channel-to-channel passthru
The following table summarizes the processor OS firmware/passthru
capability.
Remote I/O Passthru
This type of passthru allows the SLC processor system to act as a bridge
between the channel 0 or channel 1 network, and the remote I/O network
supported by the 1747-SN and 1747-BSN remote I/O scanner modules. This
allows personal computers on Ethernet, DH+, DH-485 or DF1 networks to
upload or download applications to devices such as PanelView operator
terminals and power monitors on the remote I/O network.
Refer to the remote I/O device software documentation to get details on how
to upload and download that device via remote I/O passthru
