Notice​

General Connection Behavior

The branching connections behave as follows:

  • Multiple branch connections are used to connect output coils to the left-hand side of a contact.
    • Without multiple branch connections, connections can only be made to the right-hand side of the last contact.
  • For every MPS connection, there must be a corresponding MPP connection.
  • The last contact or coil circuit must be connected by a MPP connection.
Multiple Point Read Behavior

The MRD branch connection behaves as follows:

  • MRD is NOT displayed in the ladder diagram.
  • MRD reads the operation result stored by the MPS multiple branch connection.
  • The connection performs the operation with the resulting value in the next step.
  • MRD is used to relay branching in a ladder.
    • MRD recalls, or reads, the previously sorted connection point data and forces the next contact to connect to it.

MRD Example​

The MRD multiple branch connection reads the operation result stored by the MPS multiple branch connection.
