What It Is and Where It Sits
The 6ES77301AC142BC0 is a Siemens SIMATIC IPC MD-57A industrial computer board, classified under PLCs & HMIs and Industrial Computer Boards. This is a panel-mount embedded PC intended for machine-level control, HMI hosting, or data gateway duties in a SIMATIC automation environment.
Lifecycle and Sourcing Reality
This part carries a mature lifecycle stage — it is not in active new-product introduction but remains in the Siemens portfolio for ongoing production and spares support. No official successor order code is listed, so the current MPN is the one to specify for BOM freeze or critical-spare holding.
