TSXP573623M: A Cost-Smart Path to Modern Control
Legacy PLCs often force a painful choice: expensive full-system migration or living with shrinking support. The TSXP573623M from Schneider Electric’s TSX Micro PLCs series offers a third option. It delivers modern processing power and Ethernet connectivity while preserving the architecture many plants already know. For maintenance managers, that means lower capital outlay and faster payback.
What This Controller Delivers
At its core, this PLC manages 1024 discrete I/O points and 128 analog I/O points. That capacity covers most mid-sized machine and process control duties without adding expansion hardware. Fewer components translate directly into lower hardware spend and simpler spare-part inventories.
Processing speed shapes operating cost. The unit executes Boolean instructions in 0.12 µs without a PCMCIA card. Fast scan times reduce idle machine time and improve throughput on high-cycle equipment. Over a year, those microseconds add up to real production gains.

Where It Earns Its Keep
Machine retrofit projects. A packaging line running an aging controller can swap in the TSXP573623M without a full cabinet redesign. The 1024 I/O capacity absorbs existing field devices, and Ethernet TCP/IP links the cell to plant-level systems. Integration cost drops because the wiring footprint stays familiar.
Process skids with analog loops. Fifteen process control channels support up to 45 simple loops. That suits temperature, pressure, and flow control on skid-mounted equipment. Engineers avoid buying a separate loop controller, cutting both hardware cost and panel space.
Distributed control with fieldbus devices. The communication module handles two fieldbus modules, or eight AS-Interface bus modules. Plants with existing AS-Interface wiring can reuse it, avoiding re-cabling expenses.
Installation and Setup Notes
The controller mounts in a standard PLC rack arrangement and supports up to 16 racks. Two PCMCIA slots accept memory or communication cards. A 384 Kwords program memory extension card is supported when larger programs are needed. The front panel carries multiple LEDs for quick status checks, and a RESET button triggers a cold start when required.
Plan the network layout before installation. The integrated Ethernet port runs at 10/100 Mbit/s over RJ45. The non-isolated serial link uses two female mini DIN connectors at 19.2/115 kbit/s. Confirm cable routing and grounding practices with your site’s electrical standards.
Maintenance and Long-Term Value
Inspect the unit periodically for dust buildup and secure connections. Verify LED status indicators during routine rounds. Because the TSXP573623M uses PCMCIA cards for memory and communication expansion, keep spare cards on hand to avoid extended downtime.
The cost case is straightforward. A controller that handles 1024 discrete points, 128 analog points, and Ethernet communications reduces the need for multiple specialized modules. That lowers initial purchase cost, spare-parts cost, and cabinet complexity. For plants weighing replacement against continued legacy support, this PLC often wins on total cost of ownership.
Compatibility and Integration
The TSXP573623M fits within Schneider’s TSX Micro PLCs ecosystem. It communicates over Ethernet TCP/IP and a non-isolated serial link. The communication module supports fieldbus and AS-Interface bus modules, so it integrates with common industrial networks. The application structure includes one master task, one fast task, and 64 event tasks, which helps organize complex control logic efficiently.
What to Verify Before Buying
Confirm your I/O count against the 1024 discrete and 128 analog limits. Check whether your program fits within 64 Kwords internal RAM, or plan for a PCMCIA memory card. Review network requirements against the Ethernet and serial link specifications. Finally, verify current lifecycle status and availability with SpareTechPLC before ordering. Their team can confirm stock and discuss replacement options for your existing setup.
Frequently Asked Questions
Does the TSXP573623M include a PCMCIA card?
The base unit provides 64 Kwords of internal RAM for program and data. PCMCIA cards are separate and expand data RAM to 80 Kwords or add program memory.
How fast does this PLC execute logic?
Boolean instructions run at 0.12 µs without a PCMCIA card. With the card installed, execution time is 0.17 µs.
What communication options are built in?
The unit includes Ethernet TCP/IP via RJ45 at 10/100 Mbit/s and a non-isolated serial link with two female mini DIN connectors.
How many racks can the system support?
The TSXP573623M supports up to 16 racks, allowing significant I/O expansion.
