Remote I/O Adapter Module 3 1747-ASB Module Overview The 1747-ASB module is an SLC 500 single-slot, RIO communication link module. It occupies the first slot (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.

Remote I/O Adapter Module 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. The 1747-ASB module must reside in slot 0. Slots numbered 31 and above cannot be used. IMPORTANT Installing modules in slot 31 or above results in a module error.

Remote I/O Adapter Module 11 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. 3. Slide the module into the chassis until the top and bottom tabs lock into place. To remove the module, press and hold the release located on each self-locking tab and slide the module out. 4.
Remote I/O Adapter Module There are no restrictions governing the spacing between the devices, as long as the maximum cable distance is not exceeded. Refer to the table on page 18 for baud rate and maximum cable distances. IMPORTANT No two devices can be connected to the same point on the link. An example of correct and incorrect link wiring is shown below.
Remote I/O Adapter Module 13 Link Termination A 6-pin keyed connector provides a quick connection to the RIO link and processor restart lockout switch. A user-supplied terminating resistor must be attached across lines one and two of the connector at each end of the RIO link. The size of the resistor depends on the baud rate and whether the scanner and all adapters have extended node capability, as shown in the table below.
Remote I/O Adapter Module 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.
Remote I/O Adapter Module 15 Installing I/O Module Addressing Labels Attach the Remote PLC or Remote SLC label to the outside bottom of each I/O module in your 1747-ASB chassis, as shown below. Fill out each label completely.
Remote I/O Adapter Module Installing Octal Labels The octal filter and door label kits must be used when working with a PLC processor as a master. Adhere the octal labels over the existing decimal labels, as shown below. Contact your local Allen-Bradley distributor if you need to order additional label kits.
Remote I/O Adapter Module 17 Performing System Start-up ATTENTION Never insert, remove, or wire modules with power applied to the chassis or devices wired to the module. ! Follow the steps below: 1. Cycle power one last time in save mode (SW3-8 ON). 2. Remove power from the system. 3. Remove the 1747-ASB module and set SW3-8 to the OFF position (check mode). 4. Replace the 1747-ASB module in slot 0. 5. Apply power to your system.
