2.2 Quick Start
This section provides the steps required to configure the module. After you
download the sample configuration file, please perform the following steps:
Step 1: Configure the Number of Slaves (Sessions)
The IEC 60870-5-103 protocol is a Master-slave protocol where the slaves are
typically protection equipments for substations. The MVI56-103M module
supports up to 32 slaves (total) connected to its application serial ports. Each
slave has to be configured as a session. Refer to the configuration file to enter
the number of slaves that will be connected to the MVI56-103M module:
[IEC-870-5-103 Master]
Session Count: 5 #1 to 32 - maximum number of slaves on all channels
In the example above, the module will only poll sessions 0 to 4. The module
would not poll sessions 5 to 31.
In Step 3, you will configure each session as an actual slave in the network.
Step 2: Configure the Port Communication Parameters
The user should configure the port communication parameters in order to enable
data transfer between the Master and the slave(s). The port communication
parameters include baud rate, parity, RTS ON, RTS OFF and Minimum Delay.
The IEC 60870-5-103 protocol uses two baud rates: 19200 or 9600 kb/s and
even parity.
Refer to the [IEC-870-5-103 Master Port 0] section in the configuration file in
order to configure the communication parameters for the 103M port:
[IEC-870-5-103 Master Port 0]
# Communication Parameters
Baud Rate : 19200 #Baud rate for port 9600-19200
Parity : E #N=None, O=Odd, E=Even, M=Mark, S=Space
RTS On : 0 #0-65536 mSec before message
RTS Off : 1 #0-65536 mSec after message
Minimum Delay : 10 #Minimum # of mSec before response sent
Receive Timeout: 2000 #Maximum mSec from first char to last to wait
# These parameters are protocol specific
Single char ACK F0,1 or 3: Y #Single E5 resp to ACK func 0, 1 & 3 req (Y/N)
The user should also configure the jumpers located at the bottom of the module
to select the correct electrical interface mode: RS-232, RS-422 or RS-485.
Step 3: Configure the Session (Slave) Poll Parameters
According to the IEC 60870-5-103 protocol, the Master cyclically polls data from
the slaves. The data is classified into two classes; Class 1 and Class 2. Events
belong to Class 1 and analog data to Class 2. The module can request data
through Class 1 or Class 2 requests. Responses to control command and
general interrogation commands are also sent as Class 1 data.
Refer to the [IEC-103 Master Session x] section in the configuration file in order
to configure how each slave will be polled.
