SIMATIC S7 • 4 MB FLASH MEMORY
A short-design 5 V Flash EPROM memory card for compatible SIMATIC S7-300 systems.
|
Siemens 6ES7951-1KM00-0AA0 is a SIMATIC DP field-device interface that couples PROFIBUS DP to a non-intrinsically-safe PROFIBUS PA segment. It converts the DP transmission rate to the fixed PA rate while supplying the connected PA fieldbus. The removable card supports program and data retention in compatible installed systems. Procurement should match the full article number, card format and required controller generation before replacement. |
