The CM589‑PNIO is a high‑performance PROFINET IO communication module for ABB’s AC500 PLC platform. It expands the controller’s networking capability by adding a dedicated interface that handles real‑time I/O data exchange, peer‑to‑peer PLC communication and integration with upper‑level SCADA/MES systems. Thanks to its slim housing, hot‑swap support and intuitive engineering in Automation Builder, the module delivers dependable connectivity without increasing panel space or wiring complexity.

The CM589‑PNIO is deployed wherever ABB AC500 controllers must share deterministic data with PROFINET field devices or other PLCs:
Machine Building – synchronises multi‑axis drives, vision systems and safety I/O for packaging lines and robotics.
Process Automation – links remote I/O islands, smart instruments and MCCs in water, chemical and food plants while supporting redundancy topologies.
Energy & Utilities – provides fast telemetry between turbine governors, protection relays and SCADA workstations in power generation and district heating.
Material Handling – coordinates conveyor drives, barcode readers and AGV fleets in warehouses and parcel hubs.
Building Automation – bridges HVAC PLCs with PROFINET room controllers and BMS servers for campus‑wide energy optimisation.
True Real‑Time Performance – hardware‑based PROFINET switch ensures cycle times down to 1 ms without CPU overload.
Seamless Engineering – fully integrated into ABB Automation Builder; all device parameters and GSDML files handled in a single project.
Space‑Saving Form Factor – only 28 mm wide, keeping AC500 racks compact even when multiple networks are required.
High Availability – supports Media Redundancy Protocol (MRP) and ring topologies; module can be hot‑swapped during operation.
Cyber‑Security Ready – firmware supports SNMPv3, VLAN tagging and optional Access Control Lists for secure segmentation.

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).

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.
