Pilz PNOZmulti system extension

Reasonably allocate left and right extensions: Left side extensions are usually used for analog, fieldbus, and distributed modules; The right-hand extension is used for most secure I/O and speed monitoring. Do not mix non secure modules into the right side of the secure side (unless explicitly supported).

Avoid excessive cascading: If safety interlocking across multiple controllers is required, prioritize peer-to-peer communication (such as SafetyNET p) over serial Link modules to control the total delay within 100 ms.

Use the latest firmware and configuration software: Pilz periodically updates firmware to optimize response time or add new module support. Please read the release instructions before upgrading.

Regular verification: After being put into operation, use an oscilloscope or safety analyzer to measure the actual time from input signal change to output contact opening, and compare it with the calculated value. The measured value should not exceed 20% of the calculated value.
