System Architecture & Signal Flow
The PDP401 operates as a distributed processing node within the Metso DNA controller rack. It receives process variable data from field I/O modules via the backplane bus, executes configured control algorithms (PID, cascade, ratio, feedforward), and outputs control signals to actuator I/O cards. The module communicates upstream with the Metso DNA operator workstation via the DNA network, enabling real-time monitoring, alarm management, and historian data logging. In redundant configurations, a secondary PDP401 maintains a hot-standby state, ensuring bumpless transfer upon primary module failure.

Technical FAQ
Q: Is the PDP401 compatible with Metso DNA R5 and later revisions?
A: Compatibility depends on firmware revision. Please provide your system version when inquiring so we can confirm the correct module revision.
Q: Can this module be used as a direct replacement for a failed unit without reconfiguration?
A: In most cases, yes — the replacement module can be loaded with the existing application database from the DNA engineering tool. Contact our technical team for guidance.
Q: Do you provide installation or commissioning support?
A: We provide remote technical guidance. On-site commissioning services can be arranged through our partner network upon request.
Q: What is the lead time for bulk orders (5+ units)?
A: Bulk order lead times are 7–15 business days depending on stock availability. Contact us for volume pricing.
