Processing Architecture

The Schneider TSXP57303A uses a 66 MHz RISC processor for fast execution. Its four aluminum capacitors filter power for all onboard circuits. Additionally, two supercapacitors maintain RAM contents during power interruptions. You get reliable data retention without swapping batteries.

Energy Storage Configuration

Four aluminum capacitors provide 10 ms of hold-up during power dips. Two supercapacitors store energy for long-term RAM backup. Each supercapacitor provides 5 farads at 2.7V in series configuration. They maintain program and data integrity for up to 60 days. The processor needs no battery replacement during normal operation.

Power Output Specification

This processor supplies 1000 mA at 5V to connected I/O modules. You can power up to 16 standard analog or digital modules directly. Exceeding 1000 mA requires an external power distribution module. The processor monitors total current draw for overload protection. A red LED illuminates if the current exceeds the rated limit.

Installation Steps

Mount this processor into the first slot of a Premium rack. Align the Schneider TSXP57303A with the plastic guide rails on the backplane. Push the module firmly until its locking mechanism clicks into place. Then secure the module with the top and bottom retaining screws. Connect the programming cable to the front USB port for software transfer.

Memory Management

The onboard flash memory stores up to 2048 kB of user program code. The RAM holds data variables and system status information. A PCMCIA slot accepts optional memory cards for program backup. You can transfer programs between processors using these memory cards. The processor automatically loads from the PCMCIA card on power-up.

PL7 Programming Features

This processor executes PL7 programs written in ladder, structured text, or instruction list. It supports up to 256 program sections with independent execution rates. Online program modifications occur without stopping the control process. The processor features six hardware interrupts for time-critical events. Debugging tools include real-time variable monitoring and breakpoints.

Communication Capabilities

The built-in RS-485 port supports Modbus protocol for device networking. You can connect up to 31 slaves on a single multi-drop network. A separate USB port provides high-speed connection for programming. The processor also supports ASCII serial communication for barcode readers. Additional communication modules can attach to the rack for fieldbus networks.

Application Scope

This processor suits material handling and packaging machinery applications. Many factories use the Schneider TSXP57303A for conveyor control systems. Its robust design operates in ambient temperatures from 0°C to 60°C.
