There are two different types of data mappings for the protocol. The mappings are identified and numbered, starting from one. This number is not related to the protocol instance number.
In PCM600, it is necessary to always define the mappings to be edited or viewed.
Each protocol instance has the setting parameter Mapping select, which defines the protocol mappings to be used by this instance. Several protocol instances can use the same mapping. By default, the Mapping select parameter for all the instances is set to use the mapping number one.
Note: Reboot the protection relay after changing the mapping number.
