1747-6.2
Each 1747-SN Scanner supports 4 logical racks of 256 I/O each per
logical rack. If large amounts of data needs 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 controller by a single SLC processor.
Remote I/O Passthru
Remote I/O passthru allows you to communicate between a personal
computer on the DH+ network to devices on the Remote I/O
Network. For example, a personal computer running PanelBuilder
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 option is available on the SLC 5/04 processor, the
1747-SN Series B Scanner, and the PLC-5 processor.
