Product Description
The Omron GQ-CRM21 is a CompoNet Gateway Unit for CC-Link designed to connect CompoNet slave devices to a CC-Link master network. The unit provides one CC-Link port and one CompoNet port and cyclically transfers I/O data between CompoNet Slave Units and the CC-Link Master Unit.
The GQ-CRM21 operates as a CC-Link remote device station occupying four stations and supports CC-Link Version 1.10 and Version 2.00, selectable using the unit's mode switch. It supports remote I/O communications with a maximum capacity of 2,048 I/O points for Word Slave Units (1,024 inputs and 1,024 outputs) or 512 I/O points for Bit Slave Units (256 inputs and 256 outputs).
A built-in seven-segment display provides convenient on-site monitoring and error indication. The gateway is designed to simplify system expansion and wiring by allowing CompoNet devices to be integrated into existing CC-Link networks. {"fallbackMarkdown":"([Omron](https://assets.omron.eu/downloads/latest/datasheet/en/p056_componet_datasheet_en.pdf?v=21&utm_source=chatgpt.com))","reference":{"matched_text":"","prefix":null,"start_idx":1248,"end_idx":1282,"safe_urls":["https://assets.omron.eu/downloads/latest/datasheet/en/p056_componet_datasheet_en.pdf?v=21","https://assets.omron.eu/downloads/latest/datasheet/en/p056_componet_datasheet_en.pdf?v=21&utm_source=chatgpt.com","https://www.omron-ap.com/data_pdf/cat/gq-crm21_p067-e1-01.pdf?id=2892","https://www.omron-ap.com/data_pdf/cat/gq-crm21_p067-e1-01.pdf?id=2892&utm_source=chatgpt.com"],"refs":[],"alt":"([Omron](https://assets.omron.eu/downloads/latest/datasheet/en/p056_componet_datasheet_en.pdf?v=21&utm_source=chatgpt.com))","prompt_text":null,"type":"grouped_webpages","style":null,"fallback_items":null,"status":"done","items":[{"title":"MEMO","url":"https://assets.omron.eu/downloads/latest/datasheet/en/p056_componet_datasheet_en.pdf?v=21&utm_source=chatgpt.com","attribution":"Omron","pub_date":1776207536,"snippet":"","attribution_segments":null,"supporting_websites":[{"title":"CompoNet GQ-CRM21","url":"https://www.omron-ap.com/data_pdf/cat/gq-crm21_p067-e1-01.pdf?id=2892&utm_source=chatgpt.com","pub_date":null,"snippet":"","attribution":"Omron AP"}],"refs":[{"turn_index":0,"ref_type":"search","ref_index":12},{"turn_index":0,"ref_type":"search","ref_index":14}],"hue":null,"attributions":null}],"error":null},"showLoginRequiredCard":false}
