Case 5: Configuring same Offsets for both Translation Memories and CPO as Non-Zero Value
Figure 23: COMMREQ Parameters & Corresponding Read/Write Permissives (Case 5)
Change of Data with Redundant point offset may be observed on client, which leads to
•
ambiguity.
• This type of configuration is not recommended.

Communication between controller and IEC104 client with translation memory offsets
•
Notes :
1. Point offset address is assigned with respective configured translation Offset + 1 to their
address.
2. CPO > Number of configured points will have the same effect as CPO = Number of configured
points: this configures all the points for Read / Write Operation.
3. Translation Offset address for Read and Command should not be equal for non-zero values.
4. Care should be taken during configuration of Read and Command Translation: do not allow
their respective offsets to overlap.
