Product Description

Difference between the Single and Redundant FBM.

The FBM and the drivers have been developed in such a way that using a single or redundant FBM does not require any more or less configuration effort or different software. The only important difference is the ECB-block needed for the FBM. In case of the single configuration (FBM232) an ECB200 is used, and for the redundant (FBM233) configuration an ECB202 must be configured. This difference will show up in the functions in SMDH (System Management) and off course the available information on the ECB-blocks. The two modules in a redundant configuration should be seated on the baseplate directly next to each other, starting on a uneven position. (1+2, 3+4, 5+6 etc). The 2 FBM's need only 1 ECB block, and are regarded as 1 logical FBM.

Since the letterbug naming convention of 200-series FBM's dictates that the last 2 characters determines the position of the FBM on the baseplates, this is slightly different for a redundant FBM since it occupies 2 slots. For a redundant FBM, the first 2 slots on a baseplate are called “A”, the slots 3+4 are called “B” etc. The left FBM is regarded to as the “Main” FBM, the right one is the “Backup” FBM. Although both FBM's communicate with the foreign device, only one of these two FBM's transmits the I/O to the CP, and this means that each FBM acts in certain “Role”. The FBM communicating with the CP is called the “Master” FBM and the other, “standing by” is the “Tracker”. So, depending on its position on the baseplate, an FBM is the Main or Backup, and depending on the state of the other FBM or the foreign device, both their roles can be Master or Tracker. (But not the same role at the same time off course)
