CHAPTER 5: SETTINGS
— This setting defines the time that the B90 waits for a synchronization message. The B90
IEC103 SYNC TIMEOUT
synchronizes its clock using all available sources, with the source synching more frequently overwriting the time of the
other sources. Since the synchronization message received from the IEC 60870-5-103 master is less frequent than IRIG-B,
PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs
and none of IRIG-B, PTP, or SNTP is active, the B90 sets the invalid bit in the time stamp of a time-tagged message.
The settings for the remaining menus are outlined as follows.

The binary input points are mapped using elements from a list of possible FlexLogic operands. A maximum of 96 binary
inputs (points) can be mapped this way.
The IEC 60870-5-103 point list always starts with point 0 and ends at the first "Off" value. Since the IEC 60870-5-103 point
list must be in a continuous block, any points assigned after the first "Off" point are ignored.
For each defined point, set appropriate values for the Function Type (FUN) and Information Number (INF), which form the
Information Object Identifier field of the ASDU, as defined in IEC 60870-5-103.
The binary input points are sent as Class 1 data. They are sent either as a response to a general interrogation received
from the controller or reported spontaneously. Spontaneous transmission occurs as a response to cyclic Class 2 requests.
If the B90 wants to transmit Class 1 data at that time, it demands access for Class 1 data transmission (ACD=1 in the
control field of the response).
For any change to take effect, restart the relay.
