Overview

The Allen-Bradley 80026-524-01 is a 1500 Watt, 1-Phase AC/DC Power Supply with a 56V DC Output, designed to provide reliable power in industrial automation systems.

Specifications

Data Storage and Transfer

• Up to 4000 registers can be stored and transferred to the PLC/SLC data tables.
• Supports movement of the following data types:
  • Binary
  • Integer
  • ASCII
  • Floating point

Memory Mapping

• Completely user-definable through data table configuration.

Communication Interfaces

• RS-232C Handshaking for SCADA radio/modem applications.
• RS-422/RS-485 compatibility for multi-drop applications (supports up to 32 slaves per port).
• Satellite and Packet Radio support with configurable Inter-character Timeout per port.

Software Configuration

• Configurable from processor ladder logic.
• Slave Address: 1 to 247 (0 for broadcast).
• Parity: None, odd, or even.
• Stop Bits: 1 or 2.
• Baud Rate: 300 to 38,400.
• RTS to TxD: 0 to 65535 milliseconds (1 ms resolution).
• RTS Off: 0 to 65535 milliseconds (1 ms resolution).
• Timeout: 0 to 65535 milliseconds (1 ms resolution).

Modbus Slave Specifications

• Protocol Modes:
  • RTU mode (CRC-16 error checking).
  • ASCII mode (LRC error checking with 7 and 8-bit formats).
• Supported Modbus Function Codes:
  • 1: Read Output Status
  • 2: Read Input Status
  • 3: Read Multiple Data Registers
  • 4: Read Input Registers
  • 5: Force Single Coil (Latch/Unlatch)
  • 6: Preset (Write) Single Data Register
  • 8: Loopback Test (Test 0 only)
  • 15: Multiple Coil Latch/Unlatch
  • 16: Preset (Write) Multiple Data Registers
• Supports broadcast commands from host.
• Error Status and Communication Statistics are returned to the ladder processor.

Communication Modes

• Pass-Through Mode: Allows conditional acceptance of write data by ladder logic. It transfers write commands from the host directly to the ladder for processing.
• Command Routing Mode: Supports Slave-to-Master routing for up to six slave addresses, allowing a supervisor on a slave port to access data from routed slaves.

Hardware Specifications
