3.2 Functional Overview
3.2.1 IEC 60870-5-103 Master Protocol Implementation
The following section describes the flow of data between the 103M module and
the IEC 60870-5-103 Master unit.
General Specifications
The 103M module acts as an input/output module between the IEC 60870-5-103
network and many of the other serial and network protocols, as well as several
proprietary interfaces. A 4000-word register space in the module exchanges data
between the two protocols.
General specifications include:

Built in accordance to the approved international specification

Support for the storage and transfer of up to 4000 registers between
protocols

User-definable module memory usage

Configuration via a user-generated text file (downloadable to the module)

Protocol implementation conforms to the IEC 60870-5-103 specification with
fully configurable parameters

allowing communications to be effectively debugged.
Conformance Specifications See Reference chapter for full Object Definition
document
Master Driver
The master driver supported on the application port of the module emulates an
IEC 60870-5-103 Master device.
The module communicates with one or more controlled stations on what are
referred to as sessions. A session represents a controlled device with a unique
data link layer address. Each session (controlled device) contains one data set
(sector) that is defined by the vendor of the device.
Note: The IEC 60870-5-103 specification only supports the unbalanced mode. No support is given
in the protocol for the balanced mode and the module does not support this mode.
