More Information

Overview Manuals I/O Setup SCANport Integration Installation Checks Application
  • Remote I/O communication for one compatible SCANport device
  • Supports documented Remote I/O rates and configurable rack allocation
  • DIN-rail NEMA Type 1 / IP30 enclosure with wide-range AC input

Allen-Bradley 1203-GD1 links an Allen-Bradley Remote I/O scanner with one compatible SCANport device.

Its configuration coordinates Remote I/O rack size, starting group, data mapping, baud rate, SCANport control, and fault response.

Replacement requires the exact network allocation, drive parameters, wiring, firmware, and safe-state behavior to be recorded and recommissioned.

Description
Allen-Bradley 1203-GD1 is a Remote I/O-to-SCANport communications module that links an Allen-Bradley Remote I/O scanner to one compatible SCANport device. It uses an 85–264V AC supply and a DIN-rail NEMA Type 1 / IP30 enclosure.

Remote I/O rack size, starting group, baud rate, cable network, command and reference mapping, status and feedback mapping, and SCANport control must all match the controller and drive configuration. The official manual provides the electrical, environmental, mechanical, and regulatory requirements.

Before replacement, record network allocation, scanner configuration, firmware, SCANport device parameters, wiring, and fault actions. Commission the adapter with the machine safe and verify data mapping, drive enable conditions, stop behavior, feedback, and communication-loss response.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why can 1203-GD1 show active communication while the transferred drive data is incorrect?
The scanner and adapter may have mismatched rack size, starting group, or I/O mapping. Compare the complete image and user-program word assignments.
What happens to the connected drive if 1203-GD1 loses Remote I/O communication?
The result depends on the configured communication-fault action. Verify the drive safe state and test loss-of-network behavior before operation.
How is the Remote I/O rack size selected for 1203-GD1?
Configure rack size and starting group to match the scanner allocation and the required command, reference, status, and feedback data.
What causes a rack-overlap or duplicate-address fault for 1203-GD1?
The selected rack, starting group, or scanner allocation conflicts with another adapter; compare the complete Remote I/O map before enabling the module.
Can the Remote I/O baud rate be changed without other work for 1203-GD1?
The adapter and network must use the same supported rate, and cabling length and termination must meet the corresponding Remote I/O rules.
What should be checked when the network is active but the drive does not respond for 1203-GD1?
Verify SCANport communication, control-source selection, data mapping, logic command, reference scaling, drive enable conditions, and configured fault action.
What records are needed for a 1203-GD1 replacement?
Save rack and group addressing, baud rate, block-transfer or discrete mapping, SCANport device parameters, firmware, wiring, and fault-response settings.
