Expert Review
“Reliable serial gateway for legacy S7‑300 systems.”
The CP 340 is a proven module for RS422/485 communication. It handles 3964(R) and RK512 with ease. The configuration CD simplifies startup. For new projects, choose the successor 6ES7340‑1CH02‑0AE0 – it offers better performance. But if you maintain existing lines, this version remains a solid choice. Its robust design and EMI immunity make it ideal for factory floors.
Manager’s Insight
“Plan your migration wisely.”
Since this model is end‑of‑life (2012), we recommend stocking the successor for new installations. However, for running plants, this CP 340 still works perfectly. We can support retrofit with compatible cables and adapters. Our team helps you transition without downtime. Contact us for lifecycle advice.
