1. For M580 safety Hot Standby PACs, no I/O modules are supported in the local rack. 2. This data is included in both the safe and non-safe data areas. 3. Because the SAFE task exchanges data through backplane, there is a negative impact on performance. It takes 1ms to transfer 10KB for BMEH584040S and BMEH586040S and 2ms for BMEH582040S. 4. Application Program (non-safe) + Application Data (non-safe non-retain data only ) + Application Program (safe) + Application Data (Safe) is less than 64Mbytes. There is a global memory pool of 64 Mbytes on BME•586040S CPU for Application Program and Application Data. 5. Maximum of Transfer data (non safe + safe) for redundant data is 4MB. 6. 2 GB without an external memory card. |
