Description
The ABB PM556-TP-ETH, also cataloged as the PM556-TP-ETH PLC-eCo CPU, operates as a dedicated hardware component for real-time process computation and localized I/O execution within AC500-eCo programmable logic controller platforms. The chassis-mounted processing unit runs control logic configurations, manages dedicated communication interfaces, and drives integrated digital channels natively at the hardware tier.

Industrial Control & Drive Communications
- Backplane Bus Communication Velocity and Processing Matrix The dual-axis internal bus synchronizes peripheral data across the central processing unit's 512 kB program matrix. This processing layout transfers status bits from the 8 integrated digital inputs directly into the logic processing registers within a single software execution cycle, eliminating propagation lag parallel to standard external network communication tasks.
- Profinet / EtherNet/IP Deterministic Networks and Serial Routing The core hardware integrates a dedicated RJ45 Ethernet communication layer alongside a 1x RS-485 serial interface block. This configuration allows concurrent data streaming over deterministic Ethernet topologies and Modbus RTU serial links, allowing the CPU to execute variable exchange cycles with adjacent drive networks or master SCADA nodes while using the 2 option slots to add modular expansion parameters.
Frequently Asked Questions
Q: What technical restrictions apply to configuring the 6 integrated digital transistor outputs?
A: The 6 onboard transistor outputs are designed for high-frequency solid-state switching arrays and require external 24 VDC logic potential to drive loads. They must not be connected straight to inductive AC circuits or voltage lines exceeding factory ratings to prevent thermal breakdown of the solid-state junctions.
Q: Can the PM556-TP-ETH controller be unseated from the backplane assembly while the system power is active?
A: No, unprompted hot insertion or extraction of the core CPU assembly is restricted. Disconnecting the 0.35 kg processing unit while the 24 VDC lines are live interrupts the logical backplane bus communication matrix, corrupting runtime data registers and risking damage from electrical arcing at the pin interfaces.
