Q: What physical network ports does CM589‑PNIO provide?
A: Two integrated RJ‑45 ports with an internal switch, each supporting 10/100 Mbit/s PROFINET RT traffic.
-
Q: Can I add multiple CM589‑PNIO modules to one AC500 CPU?
A: Yes, the CPU can host several communication modules in the rack; each module is assigned its own network settings in Automation Builder.
-
Q: Does the module support media redundancy?
A: It supports MRP (Media Redundancy Protocol) in manager or client mode for ring topologies.
-
Q: What cycle times can be achieved in IRT‑class motion systems?
A: With isochronous operation enabled, cycle times as low as 1 ms are achievable.
-
Q: Is a separate power supply required?
A: No. The module is powered through the AC500 back‑plane (24 V DC CPU power).
-
Q: How is firmware updated?
A: Via Automation Builder using the back‑plane bus; no SD card or external cable needed.
-
Q: What diagnostic options are available?
A: PROFINET device diagnostics, SNMP traps, LED status indicators and detailed event logs in the PLC.
-
Q: Can the CM589‑PNIO operate in extreme temperatures?
A: Yes, it is specified from –25 °C to +60 °C operating, with –40 °C to +85 °C storage.
-
Q: Does the module support time synchronisation?
A: It supports PROFINET system clock and SNTP for millisecond‑level time stamping.
-
Q: Is configuration data retained after power loss?
A: Yes, all parameters are stored in non‑volatile flash memory inside the PLC project.
