Valmet DCS System D202275 ACN Communication Gateway Node Module
D202275 is the ACN communication gateway node module of Valmet D2000 DCS system, belonging to the D2000 series rack mounted communication board. D202275 serves as a data exchange gateway between the D2000 controller, upper monitoring system, and third-party subsystems, responsible for protocol conversion, data forwarding, network isolation, and achieving data interoperability between the DCS main control unit, factory LAN, and external instrument subsystems; Simultaneously manage ACN control network data traffic, ensure real-time and deterministic transmission of control messages, and have network diagnosis and fault reporting functions. Mainly used for replacing communication module spare parts and expanding system network of old D2000 DCS systems in the papermaking and pulp industries.

Product features
- As a dedicated communication gateway for the D2000 system ACN network, it enables data exchange and protocol conversion between the DCS controller, upper computer, and third-party automation subsystems.
- Redundant ACN control network with dual Ethernet ports, supporting automatic switching in case of network link failures, ensuring uninterrupted transmission of process control data.
- Independently maintain service ports for engineers to configure, diagnose, and download programs online without interfering with the production control network.
- The backplane bus is electrically isolated from the network side, effectively isolating external network surges and electromagnetic interference, and protecting DCS main control and I/O cards.
- Complete hardware self diagnostic function, real-time monitoring of network links, communication messages, board hardware status, and uploading fault information to DCS system alarm.
- The panel LED indicator light intuitively displays module operation, bus communication, network port links, and fault alarm status, facilitating quick on-site troubleshooting.
- The circuit board is equipped with a three proof coating, which is resistant to moisture, fiber dust, and vibration, and is suitable for harsh working conditions in paper workshops.
- Standard D2000 rack slot installation, supports hot swapping, reduces system downtime and maintenance time for fault replacement, compatible with D2000 series backboards.
