Page 3: 1747-Asb Module Overview
(slot 0) of a 1746 remote chassis, where the SLC processor normally resides. The 1747-ASB module is an adapter, or slave, on the RIO link, and the master of the remote chassis and remote expansion chassis in which it is installed. Remote expansion chassis are optional. -
Page 4: Required Tools And Equipment
Review the power requirements of your system to ensure that the chassis supports placement of the 1747-ASB module. The adapter consumes 600 mA at 5V dc. For a detailed list of device load currents, refer to the SLC 500 Fixed Hardware Style Installation and Operation Manual, publication number 1747-6.21;... -
Page 5: Slot Addressing
Slot Numbering The 1747-ASB module is capable of controlling 30 slots. When expansion chassis are used, the 1747-ASB module treats all of the I/O modules as if they are installed in a single chassis. The remote chassis and remote expansion chassis slots are numbered from 0 to 30. -

Slot For more information on addressing, refer to the Remote I/O Adapter Module User Manual, publication number 1747-6.13. Configuring the Module The 1747-ASB module parameters are configured by three DIP switches, shown below. DIP Switches Publication 1747-IN014C-EN-P - January 2003... - Page 7 • Starting Logical Group Number (Logical Group) - is the 1747-ASB module’s starting logical group number within the scanner’s image. • Baud Rate (Baud Rate) - is the 1747-ASB module’s RIO link communication rate. The baud rate must be the same for all adapters on the RIO link.

2. Install the module in slot 0 of the remote chassis by aligning the circuit board with the chassis card guide. The 1747-ASB module must be installed only in slot 0 (the left slot) of the remote chassis. Do not install the 1747-ASB module in the remote expansion chassis. - Page 12 No two devices can be connected to the same point on the link.

Page 14: Wiring A Processor Restart Lockout Switch
Wiring a Processor Restart Lockout Switch When processor restart lockout is enabled (SW3-2) and communications are restored, the 1747-ASB module does not respond to any type of communication, or communication commands until terminals IN and RET are momentarily shorted together. This occurs while the RIO scanner is attempting to communicate with the 1747-ASB module. -
