6DL3100-8AC05 | SIMATIC S5-115U CPU 943, 48 KB Work Mem., 2× PG/OP IF, 2× S5 Bus, 24V DC
6DL3100-8AC05 SIMATIC S5-115U CPU 943 central processing unit — 48 KB work memory, 2× serial IF (PG/OP), 2× S5 system bus, 24 V DC powered. For S5-115U rack (UR/ER), programmed with STEP 5.
Product Overview
6DL3100-8AC05 (also listed as 6ES5943-8AC05 — S5-115U CPU 943) is the central processing unit for the SIMATIC S5-115U programmable controller system. It provides 48 KB work memory (RAM, expandable with EPROM memory sub-module), two integrated serial interfaces (IF1 = PG/OP for programming/HMI at 9.6–19.2 kbps AS511; IF2 = optional PG/OP or printer/baud rate selectable), and connects to up to two S5 I/O buses for central and expansion racks (UR/ER with IM 305/306/308). The CPU is powered from the S5-115U rack's 24 V DC supply module (PS 942 / PS 945) — no separate power connection on the CPU itself. Programming is via STEP 5 (PG720/740/760 or SIMATIC Manager with S5 option package). This is a legacy / mature product — recommends migration to SIMATIC S7-1500 / S7-1200 for new projects.

Key Features
Proven S5-115U Architecture: Widely deployed in process and manufacturing — direct spare/replacement for existing installed base.
Dual Serial Ports: IF1 for PG/OP programming & HMI; IF2 configurable as second PG/OP or printer output for hardcopy diagnostics/logs.
EPROM Sub-Module Support: Program can be burned to EPROM for non-volatile operation — no battery dependency for code retention (battery backs up retentive data only).
Two S5 Bus Interfaces: Connects central UR + up to 3 expansion ERs — scales to typical medium-size machine/process applications.
STEP 5 Compatible: Familiar programming environment (STL/LAD/CSF) for maintenance teams with legacy S5 expertise.
Typical Applications
Legacy Process Plant Retrofit / Spare: Replacement CPU for running S5-115U systems in water treatment, batch mixing, boiler control where full migration is deferred.
Machine Tool / Special Machinery Service: Keeping older transfer lines, presses, and custom-built equipment operational with original S5 control logic.
OEM Stand-Alone Equipment (Installed Base): Where S5-115U was specified originally and only a like-for-like replacement is acceptable to avoid re-validation.
Training / Maintenance Stock: Strategic spare held by facilities running S5 to minimize downtime.
