This chapter provides an overview of how the MVI46-103M module transfers
data using the 103M protocol. You should understand the important concepts in
this chapter before you begin installing and configuring the module.
The standards used to build the module are listed in the following table:
PUBLICATION TITLE
IEC 60870-5-103 Companion Standard for the informative interface of protection equipment.
IEC 60870-5-103
Annex A Generic functions --Examples of constructing a directory
IEC 60870-5-1 Transmission Frame Formats
