Backplane Bus Communication Velocity & Network Integration
The PM590 CPU processor interfaces natively with the AC500 terminal base backplane bus to ensure high-speed cyclic I/O updating and deterministic task processing across local expansion cards. Utilizing its 2 MB onboard flash memory architecture, the unit manages backplane bus communication velocity and firmware flash compatibility while coordinating multi-channel data transfers across Ethernet TCP/IP, dual serial links, and FieldBus Plug (FBP) interfaces. Onboard execution logic scales across complex I/O topologies without introducing processing bottlenecks to local or distributed bus segments.
Frequently Asked Questions
Q: What memory medium is supported for offline program transfers or data logging on the PM590?
A: The PM590 features an integrated SD card slot that accepts industrial SD cards for user program backups, firmware updates, and direct data logging.
Q: What is the IP enclosure rating and mounting requirement for the PM590 processor?
A: The PM590 carries an IP20 protection rating and must be mounted directly onto standard 35 mm DIN rails inside a protective control cabinet.
Field Installation Guidelines
- Disconnect all 24 VDC power sources to the AC500 terminal base before snap-mounting the PM590 CPU module onto the DIN rail.
- Seat the module firmly onto the terminal base guides until the mechanical locking mechanism engages completely.
- Wire the 24 VDC supply lines to the terminal block using recommended wire gauges, verifying correct polarity before energizing.
- Connect Ethernet and serial RS232/RS485 communications cables using shielded twisted-pair cabling to minimize electromagnetic noise.
- Bond the DIN rail and cabinet panel to primary earth ground using low-impedance copper conductors to protect against transient overvoltage spikes.
