Below you will find brief information for Remote I/O Scanner 1747 SN, Remote I/O Scanner 1747 ASB. The 1747-SN Remote I/O Scanner is used to connect an SLC 500 processor to remotely located I/O devices, such as the 1746 I/O chassis. This allows you to extend the reach of your control system and access signals from a distance. The scanner transmits data between the processor and the remote I/O devices, enabling you to monitor and control processes in areas where you can't have the processor directly available. It also allows for the use of complementary I/O, where two adapters can share the same image space to increase the number of I/O points supported.

Frequently Answers and Questions

What is the maximum communication distance of the 1747-SN scanner?

The maximum communication distance of the 1747-SN scanner is 3,048 meters (10,000 feet).

What types of I/O devices are compatible with the 1747-SN scanner?

The 1747-SN scanner is compatible with 1746 I/O chassis and other RIO compatible Allen-Bradley operator interface and control devices.

Is it possible to connect multiple scanners to a single SLC 500 processor?

Yes, multiple scanners can be connected to a single SLC 500 processor, but limitations may apply based on backplane power requirements, processor I/O data table limits, and memory available.

What is the maximum number of logical racks that the 1747-SN scanner can address?

The 1747-SN scanner can address up to 4 logical racks of discrete data.

What is the purpose of complementary I/O?

Complementary I/O allows you to overlap the images of two adapters in the scanner’s I/O image, enabling you to use the full 32 input and 32 output word image for I/O addressing. This allows for more efficient use of the scanner’s image space and increases the number of I/O points supported.

How does the 1747-SN scanner transfer data with remote I/O devices?

The 1747-SN scanner transfers data with remote I/O devices using discrete I/O transfers and block transfers. Discrete I/O transfers are the simplest and fastest way for the scanner and the adapter to communicate, while block transfers allow for the transfer of large amounts of data.
