Work memory sits at 4 MB for program and 20 MB for data — enough for medium-to-large process logic with recipe arrays. The C/C++ Runtime is preinstalled, so you can drop in compiled algorithms alongside conventional ladder without a separate engineering step. Four onboard interfaces: PROFINET IRT with a 2-port switch for isochronous motion or fast line, a second PROFINET RT port for I/O daisy-chains, a plain Ethernet port for HMI or IT integration, and a PROFIBUS port for legacy drives or remote I/O. Bit performance is rated at 1 ns — short cycle times even with mixed language code. ## Integration note: memory card required, no surprises on footprint A SIMATIC Memory Card of at least 2 GB must be inserted for operation — the CPU has no onboard program-holding flash. The packaging dimensions are 15.5 x 15.5 x 5.00 cm, which matches the standard S7-1500 single-wide form factor; panel cut-outs and DIN-rail attachment are identical to the industrial version. Mounting orientation and clearance follow the usual S7-1500 guidelines: 20 mm above and below for airflow.","metaTitle":"Siemens 6AG1518-4AX00-4AB0 SIPLUS CPU, 4 MB, 4 Interfaces","metaDescription":"Active production SIPLUS S7-1500 CPU with conformal coating, 4 MB program memory, 20 MB data, 4 interfaces (PN IRT, PN RT, Ethernet, PROFIBUS).
