PLCs, Power Supplies & Others

The 6FM1480-2BC00 processor module runs program logic inside SIMATIC S5 controllers. Siemens builds this module for legacy systems that still drive critical production equipment. It executes user programs and manages I/O updates through the S5 backplane bus.

Processor and Memory Specifications

The module carries a 16-bit processor that executes ladder logic and statement list programs. It provides 64 KB of program memory for user code and function blocks. A 32 KB data memory area stores flags, timers, and counters during operation. Additionally, the module supports up to 256 I/O addresses across the backplane.

Physical Dimensions and Power Details

The module measures 185 mm in height, 25 mm in width, and 130 mm in depth. It weighs approximately 0.4 kg, and it seats in a standard S5 rack slot. The backplane supplies 5 VDC at a maximum draw of 0.8 A. Gold-plated edge contacts resist corrosion in humid plant rooms.

Installation and Configuration Notes

Technicians slide the 6FM1480-2BC00 into its rack slot and tighten the front retaining screw. Engineers download programs through the S5 programming interface before switching the CPU to run mode. The module then scans inputs and updates outputs on a fixed cycle. Consequently, existing S5 machines keep running with spare-part continuity.

Why This Module Supports Legacy S5 Retrofits

Maintenance teams choose the 6FM1480-2BC00 for its 64 KB program memory and 256 I/O address range. The gold-plated contacts hold up in humid and corrosive plant rooms. Direct slot compatibility removes the need for adapter hardware. This processor module serves plants that keep S5 systems running for gradual migration.
