Remote I/O Network
Each 1747-SN scanner supports 4 logical racks of 256 I/O each per logical
rack. If large amounts of data need to be transferred to a device such as a
PanelView operator interface, the 1747-SN series B scanner supports block
transfer of up to 64 words of data. Up to 16 devices can be connected to a
single remote I/O network. The SLC system supports multiple 1747-SN
scanners if more devices are required to be controlled by a single SLC
processor.
Remote I/O Passthru
Remote I/O passthru enables communication between a personal computer
on the same network as an SLC 5/03, 5/04, or 5/05 processor to devices on
the remote I/O network. For example, a personal computer running
PanelBuilder32 software and communicating on the DH+ network could
upload and download applications from a PanelView operator terminal
communicating on the remote I/O network. This feature eliminates the need
to physically connect the personal computer to the PanelView operator
terminal when you need to change the application. This capability is available
on the 1747-SN series B scanner, and the 1747-BSN backup scanner.
