Industrial Control and Volatile Application Memory Execution
Modular PLC processors utilize high-speed static RAM extension cards to scale user application memory without altering CPU hardware architectures. The TSXMRPP224K card installs directly into Slot 0 of Modicon Premium TSX57 series processors, providing 224 kB of zero-wait-state memory for execution of complex IEC 61131-3 logic routines, recipe tables, and extended data block structures. Fast bus access speeds preserve deterministic cycle times during high-speed sequential processing and multi-axis motion tasks.
Frequently Asked Questions
Q: Is the program data saved on the TSXMRPP224K retained if the card is removed from the processor?
A: No. SRAM is volatile memory; data retention relies on the backup battery located inside the TSX57 processor host while the card remains seated in Slot 0.
Q: Can the TSXMRPP224K memory card be inserted or removed while the CPU is powered?
A: No. Memory cards must be installed or removed only when processor power is completely shut down to prevent memory corruption or hardware damage.
Field Installation Guidelines
-
Shut down main power to the PLC rack and wait for processor diagnostic LEDs to turn off completely.
-
Open the memory card slot cover located on the front panel of the TSX57 processor module.
-
Orient the TSXMRPP224K PCMCIA card with the connector facing inward and the label facing left/front per slot guides.
-
Slide the card firmly into Slot 0 until the ejector mechanism latches and the card seats completely into the internal backplane connector.
-
Apply power to the rack, connect Unity Pro / PL7 Junior programming software, and verify that extended 224 kB memory is recognized in the processor configuration properties.
