Updating identification of the String Monitor Units
To identify the String Monitor Units in the Sunny String-Monitor, each Piggy-Back for data processing
is assigned a number as an "SSM identifier". This makes troubleshooting easier, for example, in the
event of a string failure, or deviating string currents. The "SSM Identifier" does not correspond to the
network address which is automatically assigned upon detection. The Sunny Central Control supports
up to 40 "SSM Identifiers".
1. Select Device Set-up > SMUs > Devices > Parameters.
2. Select the String Monitor Unit you want.
3. Select the SSM Identifier parameter.
4. Give the String Monitor Unit you want a unique identification number between 1 and 40.
5. Adopt all changes with the [Enter] key.
