Communication Capabilities & Network Setup

• The 1747-SN communicates with compatible RIO adapter modules. It requests I/O status updates, messages, and diagnostics over the RIO network.
• This scanner supports remote I/O passthru. It also handles downloading, uploading, and commissioning of SLC500 controllers.
• Connect devices in a daisy-chain topology. Terminate both ends of the network with an 82 Ohm resistor.
• Use Belden 9463 cable specifically for RIO communication. This cable ensures signal integrity over long distances.
• Four selectable baud rates are available. Use DIP switches 1 and 2 to configure the transmission speed.
• The module supports both extended and non-extended node capabilities. This provides flexible integration options.
• Data transfer includes communication with PanelView graphic terminals. The 1747-SN also supports third-party protocol converters.

Frequently Asked Questions (FAQ)

• Q: Is the 1747-SN compatible with SLC 5/03 processors?
  A: Yes, the 1747-SN works with SLC 5/02, 5/03, 5/04, and 5/05 processors. It fits all these SLC 500 family controllers.
• Q: What cable does the 1747-SN require?
  A: This scanner requires Belden 9463 cable for RIO communication. Do not use standard RS-232 cables for this port.
• Q: What is the maximum cable length for RIO communication?
  A: At 57.6 Kbaud, maximum length is 3048 meters (10,000 feet). At 230.4 Kbaud, maximum length is 762 meters (2500 feet).
• Q: How many devices can connect to the 1747-SN network?
  A: Normal mode supports 16 devices. Complementary mode supports 32 devices. Both ends need 82 Ohm termination resistors.
• Q: Do I need terminating resistors for the RIO network?
  A: Yes, always install 82 Ohm, 1/2 Watt resistors at both ends of the daisy-chain. This prevents signal reflections.
• Q: How do I select the baud rate on the 1747-SN?
  A: Use DIP switches 1 and 2 on the module. Four baud rates are selectable. Refer to the manual for switch positions.
• Q: Does the 1747-SN support remote I/O passthru?
  A: Yes, this scanner supports remote I/O passthru. It also handles downloading and uploading to SLC500 controllers.
• Q: What are the agency certifications for this module?
  A: The 1747-SN has UL/C-UL Class I, Division 2 certification. It also carries CE and C-Tick marks for global use.
• Q: Do you have stock available?
