Memory Submodules for S5-115U - New Revision Levels
Concerns products with the Order Nos.: 6ES5 375-0LD11 375 RAM submodule, 8 Kbyte 6ES5 375-0LD21 375 RAM submodule, 8 Kbyte 6ES5 941-7UB11 CPU 941B, 18 Kbyte 6ES5 942-7UB11 CPU 942B, 42 Kbyte If the above CPUs are operated with the RAM submodules 375-0LD11/21 (revision levels A06 or A04), faulty program pro- cessing can occur. _Description of the problem:_ The CPU will sporadically enter STOP mode with various fault con- ditions. In this case the fault register displayed in the ISTACK is never identical with the STEP 5 operation stored in the RAM submodule. Only a few cases have occurred and only memory submodules with a specific combination of components are affected. The criti- cal components can be identified from their labels as follows: KM 6264... ...Y KOREA The fault has been corrected with the new revision levels A07 and A05. _Upgrading:_ If the fault occurs, return the memory submodules to your local Siemens office. Your SIMATIC contact will make the necessary arrangements. -------------------------------
