Technical Specifications

Note: Capacity and performance depend on the rack configuration, installed modules, memory options, and application design. The supplied dimensions and weight are retained as listing parameters; verify the exact hardware and packaging before shipping or installation.

Function and Working Principle

The TSXP573623AM acts as the central processing unit of a Modicon Premium PLC station. It executes the application program, processes incoming information, updates control outputs, and coordinates data exchange with supported system components.

1. PLC Program Execution

The processor executes logic developed using the supported PL7 Junior/Pro software environment. Depending on the application, the program may contain interlocking logic, sequencing, timers, counters, arithmetic operations, alarm handling, and process-control routines.

The processor supports a master task, a fast task, and event tasks. These execution structures allow engineers to organize application logic according to response-time and operational requirements.

For example, a packaging machine may use the master task for general sequence control and a faster task for functions requiring more frequent processing. The actual task configuration depends on the application and its timing requirements.

2. Input and Output Processing

A PLC receives information from sensors and other field devices through its input modules. The processor evaluates the input states and executes the programmed logic before updating the relevant outputs.

The Modicon Premium platform supports discrete and analog I/O modules, allowing the controller to manage both on/off signals and measured process values.

Typical input signals may include limit switches, pressure transmitters, temperature measurements, and motor status contacts. Outputs may control relays, contactors, solenoid valves, indicators, and other compatible field devices through the appropriate I/O modules.

3. Data Storage and Memory Expansion

The processor provides internal RAM for application program and data storage. Without a PCMCIA extension card, the documented internal memory is 64 Kwords for program and data.

Compatible PCMCIA memory cards can provide additional storage for application programs and data. The available capacity depends on the card type and system configuration.

For maintenance purposes, engineers should document the installed memory card, program version, and application backup. Replacing a processor without preserving the required application files and configuration may prevent the controller from returning to service as intended.

4. Ethernet Communication

The integrated Ethernet TCP/IP interface supports communication with compatible programming and supervisory equipment over an industrial Ethernet network.

Depending on the system architecture, Ethernet communication may support PLC programming, data exchange, diagnostics, and supervisory monitoring. The actual protocols, services, and network functions available depend on the processor configuration and software environment.

Network addressing, cable routing, and access permissions should be configured according to the plant’s communication standards.

5. Serial Communication

The TSXP573623AM also provides two non-isolated serial communication links using female mini-DIN connectors.

These interfaces can support compatible programming or communication arrangements, depending on the selected connection and device requirements. Engineers should verify the correct cable, port assignment, serial settings, and protocol before connecting external equipment.

Because the serial links are non-isolated, grounding and electrical compatibility require particular attention when integrating devices with different electrical references.

Role in Industrial Control Systems

The TSXP573623AM is the processing core of a Modicon Premium PLC station. It coordinates control logic, communicates with system modules, and provides the processing resources needed to automate industrial equipment.

PLC-Based Machine Control

In manufacturing systems, the processor can execute sequences for conveyors, packaging machinery, assembly equipment, and material-handling systems.

It receives status information from field devices, evaluates operating conditions, and sends control commands through compatible output modules. Interlocks and fault-handling logic help ensure that the machine responds appropriately to changing conditions.

Process Automation

The processor can also be used in industrial process-control systems involving analog measurements, discrete equipment states, and programmed control sequences.

Depending on the application and installed modules, the controller can coordinate pumps, valves, fans, auxiliary equipment, and process alarms.

The number of supported channels and achievable control performance depend on the processor configuration and the system’s engineering design.

Supervisory System Integration

The integrated Ethernet interface allows the processor to participate in a compatible supervisory architecture. A supervisory control and data acquisition (SCADA) system may collect operating data, display alarms, and present process information to operators.

Communication must be configured using the supported interfaces and software. Engineers should verify the exact protocol and system compatibility rather than assume that every modern Ethernet-based automation service is supported.

Legacy System Continuity

The TSXP573623AM is relevant to facilities that continue to operate Modicon Premium systems. Maintaining the original processor may reduce the immediate need for a complete control-system redesign.

However, the discontinued status means that replacement planning should include spare-parts availability, software compatibility, backup procedures, and a longer-term migration strategy.

Industrial Applications

1. Manufacturing and Assembly Lines

The processor can manage machine sequences involving sensors, pneumatic actuators, motor starters, and other field equipment.

In an assembly line, the PLC may verify part presence, control the sequence of operations, monitor equipment status, and coordinate transfers between stations.

The controller’s task structure and I/O capacity allow engineers to organize machine logic according to process requirements.

2. Packaging Machinery

Packaging equipment often requires coordinated operation of conveyors, feeders, sensors, and actuators. The processor can execute the logic that synchronizes these devices and manages machine states.

Ethernet and serial communication may support compatible operator interfaces and supervisory equipment, depending on the installation.

3. Water and Wastewater Systems

In suitable control architectures, the Modicon Premium platform can monitor tank levels, pump states, valve positions, and other process variables.

The processor evaluates sensor information and coordinates control outputs through compatible I/O modules. Alarm logic can identify abnormal conditions and support operator response.

Actual suitability depends on the required I/O capacity, environmental conditions, control strategy, and availability of compatible equipment.

4. Industrial Utilities

Utility systems may use PLCs to coordinate pumps, fans, auxiliary motors, and monitoring devices.

The TSXP573623AM can execute control sequences and exchange information with compatible supervisory systems. Engineers should confirm that its capabilities and lifecycle status meet the requirements of the installation.

5. Material Handling

Material-handling systems may include conveyor sections, transfer mechanisms, sorting devices, and safety interlocks.

A PLC processor coordinates these elements using field inputs and programmed logic. The TSXP573623AM may be suitable for maintaining an existing Modicon Premium installation where the processor, rack, and associated modules remain compatible.

Installation and System Integration

Correct installation and configuration are essential for reliable operation of the TSXP573623AM.

1. Verify Rack Compatibility

The processor must be installed in a compatible Modicon Premium rack. Before replacement, confirm the rack type, slot arrangement, power supply, existing modules, and any hardware restrictions.

A processor with a similar appearance or related model number should not be assumed to be interchangeable without checking the manufacturer’s compatibility information.

2. Confirm Power Requirements

Manufacturer documentation specifies a current consumption of 1,360 mA for this processor configuration. The rack power supply must have sufficient capacity for the processor and all installed modules.

Calculate the total rack load using the requirements of each component. Insufficient power capacity may lead to unstable operation or startup problems.

3. Configure Ethernet and Serial Interfaces

For Ethernet communication, verify the correct network connection, IP configuration, addressing plan, and compatibility with the intended programming or supervisory equipment.

For serial communication, check the required cable, port assignment, communication speed, and device settings. The two serial interfaces are non-isolated, so electrical references and grounding must be evaluated carefully.

4. Manage Application Programs and Memory

Before removing a working processor, back up the application program, configuration, and relevant documentation wherever possible.

Record the installed PCMCIA memory card and confirm that the replacement processor supports the required program and data configuration. After installation, verify the program version and ensure that the controller starts with the intended application.

5. Commission the PLC Station

After installing the processor, verify rack power, module recognition, communication status, and controller diagnostics.

Test representative inputs and outputs, task execution, alarms, interlocks, and communication with connected equipment. Confirm that the machine operates safely before returning the system to normal production.

6. Maintain Environmental and Electrical Conditions

Install the rack in an appropriate control cabinet and protect it from excessive dust, moisture, vibration, and temperature extremes.

Inspect connectors, wiring, grounding, and cabinet conditions during scheduled maintenance. Avoid inserting or removing modules under power unless the specific hardware and procedure explicitly support that operation.

Compatible System Components

The TSXP573623AM is designed to work as part of the Modicon Premium automation platform. Exact compatibility depends on the installed rack, module references, software versions, and communication configuration.

These components are examples of equipment that may be used in a complete system. They are not necessarily included with the processor.

Alternative Models and Replacement Considerations

The TSXP573623AM has been discontinued. Schneider Electric identifies the Modicon M580 BMEP583020 as a replacement direction, but migration requires an engineering assessment rather than a simple module substitution.

Before selecting a replacement, compare the following:

• Rack and backplane compatibility.
• Application program and software version.
• Internal memory and PCMCIA card requirements.
• Ethernet and serial communication functions.
• Discrete and analog I/O capacity.
• Application-specific and process-control requirements.
• Power supply capacity and installed modules.
• Communication with HMI, SCADA, and external devices.
• Mounting and wiring arrangements.
• Lifecycle support and long-term spare-parts availability.

A newer processor may provide greater capacity or newer communication options, but those improvements do not guarantee direct compatibility with an existing Premium rack or application.
