Functions

Control execution

Provides 256 kB user program memory and 416 kB user data memory with official cycle times of 0.05 ms binary, 0.06 ms word and 0.50 ms floating-point per 1000 instructions.

Local diagnostics

The monochrome LCD, eight function keys and three LEDs provide local status and diagnostic access.

Local expansion

The CPU supports up to 10 local expansion modules within the published digital and analog I/O limits.

Interfaces

Ethernet TCP/IP

The PM581-ETH variant includes an integrated Ethernet interface presented through the Ethernet terminal base.

Dual serial ports

COM1 and COM2 are configurable RS232/RS485 ports for programming, Modbus Master/Slave, ASCII or CS31 Master communication.

FieldBusPlug and I/O-Bus

A FieldBusPlug interface and local I/O-Bus connect supported communication and I/O components.

Installation

Terminal base selection

Install PM581-ETH on a compatible TB5xx-ETH terminal base selected for one, two or four communication-module slots.

Power and mounting

Connect 24 V DC at the terminal base and mount horizontally on a 35 mm DIN rail; vertical mounting requires the official derating conditions.

Environmental limits

Maintain IP20 protection and the published 0 to +60 degrees C operating and -40 to +70 degrees C storage limits.

Compatibility

Terminal bases

Use an Ethernet terminal base such as TB511-ETH, TB521-ETH or TB541-ETH; non-Ethernet and ARCNET bases are not equivalent.

Memory card

The CPU supports the ABB SD memory card family specified for the AC500 platform.

Revision control

The current product page identifies PM581-ETH-V14x and product ID 1SAP140100R0270; verify revision and engineering-software compatibility before replacement.

FAQ

Q1. How can the quoted unit be verified as the exact PM581-ETH?

Confirm ABB type designation PM581-ETH and current product ID 1SAP140100R0270 on the quotation, nameplate and packing label. Verify 256 kB program memory, Ethernet, two RS232/RS485 ports, FieldBusPlug, SD slot and LCD display.

Q2. How can New, Used and Refurbished PM581-ETH units be distinguished?

Request current photos of the label, housing, LCD, keys, Ethernet connection, serial terminals, FieldBusPlug interface, terminal contacts and packaging. A New unit should show no mounting, wiring or connector wear, with condition documented in writing.

Q3. How should the supplier be checked before purchasing PM581-ETH?

Verify legal registration, physical address, company payment account, written quotation, return terms and traceable references. All records should consistently identify PM581-ETH and the offered revision or product ID.

Q4. Which engineering specifications require confirmation?

Check the 24 V DC supply, 67.5 x 76 x 62 mm dimensions, 0.155 kg weight, 256 kB program memory, TB5xx-ETH base, Ethernet TCP/IP, dual RS232/RS485 ports, FieldBusPlug and local I/O requirements.

Q5. What evidence should be requested before payment?

Request timestamped photos or video showing PM581-ETH, product ID, serial number, LCD, keys, interfaces, terminal contacts, compatible terminal base and sealed packaging.

Q6. Can PM581, PM571-ETH or another PM581-ETH revision replace this model?

Not automatically. Ethernet hardware, program memory, I/O capacity, terminal-base type, firmware and engineering-software compatibility may differ. Approve substitution only after the full product ID and application requirements are checked.
