Compatibility With Previous Product; Extended Functionality Compared With Previous Product - Siemens SIMATIC NET S7-400 Equipment Manual

Application and functions

1.5 Compatibility with previous product

Special feature of the DP mode:
If the CPU is in RUN mode at the same time, the memory reset is rejected by the CP.
DP diagnostics frames when the CPU is in STOP
All diagnostic frames from DPV0 standard slaves and all DP alarm frames from DP-S7/DP-V1
standard slaves arriving when the CPU is in STOP mode are handled as follows:
• In "S7-compatible" mode
The problems that still exist at the transition from CPU STOP to CPU RUN are passed on the
user program.
• In DP-V1 mode
The diagnostics/interrupt frames are forwarded even when the CPU is in STOP mode,
however, they must be evaluated by a suitable user program when the module starts up.
