IEC 61850 MMS Write
For writable data, drag and drop the O
PER
structure from the tree view on the left
to the right-hand side of the window.
Important: In addition to the
O
PER
structure, some IEDs also offer SBO
W
and
Cancel structures within the same Data Object. For the gateway, you only need to
map the
O
PER
structure. Do not map the SBO
W
. The C
ANCEL
structure should
only be mapped if it is required.
We strongly recommend the user map all of the Data Attributes surrounding the
actual controlled value, and setup another exchange to read it before changing
the control value and performing a write from the PLC side.
In ProSoft EIP-61850 Configuration Manager O
PER
structures that are supported
by the IED have a green indicator, meaning that these may be mapped to the
gateway. Those with a red indicator are not required to be mapped.
