FAQ

What type of redundancy configuration does the PM866-2 support?
The PM866-2 supports hot-standby redundancy in the AC 800M system, ensuring uninterrupted control in case of processor failure.

How is the memory architecture organized for firmware and runtime data?
The unit uses 4 MB flash PROM for firmware storage and 64 MB SDRAM for runtime operations, providing fast execution and stable firmware retention.

What are the power requirements for safe operation?
Typical power dissipation is 5.1 W, increasing to 8.6 W when supplying the ModuleBus and CEXBus. Input is via a four-pin connector (L+, L–, SA, SB).

How is processor failure detected and handled?
Redundant units continuously monitor each other. In case of a failure, the standby processor immediately assumes control without process interruption.

What is the maximum current draw under full load?
The maximum current consumption is 360 mA, excluding ModuleBus and CEXBus supply.

Can the PM866-2 firmware be updated in situ?
Yes, firmware updates are performed via the flash PROM without removing the processor unit from the system.

What environmental conditions must be maintained for reliable operation?
The unit is designed for industrial environments as specified in AC 800M hardware manuals, including specified temperature, humidity, and vibration limits.

How are diagnostics and status monitoring performed?
Integrated diagnostics provide real-time monitoring through the AC 800M system, including status LEDs and system messages for fault detection.
