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.
Please refer to the [IEC-103 Master Session x] section in the configuration file in
order to configure how each slave will be polled.
Initially, the user should enter the MVI46-103M port number that will be
connected to the session (slave) using the "Communication Port" parameter.
Valid values are 0 or 1.
These parameters include the Data Link Address, which is the slave address that
identifies all protection equipment on the network. There should be a unique
number for each slave on the network. There are also certain parameters that
pertain to how the Class 1 and Class 2 polls will be used for data transfer.
You must enter the number of sectors for each session using the Sector Count
parameter. The module accepts up to 3 sectors per session.
[IEC-103 Master Session 0]
Communication Port : 0 #Index of COM port for session (0 or 1)
Sector Count : 5 #5 is max for this version of app
Data Link Address : 0 #Range is 0 to 65535 DL address of slave
Failure Delay : 3 #Min Sec to delay before poll of offline slave
#(0 to 2000 seconds)
Confirm Timeout : 20000 #0 to 2^32-1 mSec to wait for DL confirm
Retry Count : 5 #0 to 255 retries for if no confirm
Response Timeout : 5000 #Timeout for confirm of req (0 to 2^32-1)
C1/C2 Poll Count Pend : 6 #class 1 or 2 polls before next slave tried (0-
65535)
Class 1 Polls : 10 #Max class 1 polls to this session
Class 1 Pend delay : 1000 #Min mSec delay between call (0 to 2^32-1)
Class 2 Pend delay : 1000 #Min mSec delay between call (0 to 2^32-1)
Class 1 Poll delay : 1000 #Min mSec delay between call (0 to 2^32-1)
Class 2 Poll delay : 1000 #Min mSec delay between call (0 to 2^32-1)
This step should be repeated for each session to be used. For example, if the
user selected 8 sessions during Step 1, he or she should configure sessions 0 to
7:
[IEC-103 Master Session 0]
[IEC-103 Master Session 1]
[IEC-103 Master Session 2]
[IEC-103 Master Session 3]
[IEC-103 Master Session 4]
[IEC-103 Master Session 5]
[IEC-103 Master Session 6]
[IEC-103 Master Session 7]
