Site Configuration

5-46

Send broadcast reset after restart <YES/NO>

[YES]:

Specify YES to broadcast to all units defined after Reset Load in order to synchronize at
Transport Multiplex level.

Restart declaration time out <5-200> Sec

[30]:

Time interval between two Restart control frames at Transport Multiplex level.

Time out for URGE transmission after hole detection <0-3000> Sec.

[15]:

The period of time after which an “urge” frame will be issued if a gap formed at Transport
Multiplex level. A response to the urge frame means that the gap will never be filled since all
Data Link layer retries have already been exhausted.

Size of TX queue <30-200>

[160]:

Since Transport Multiplex consumes buffers for transmission, the number of buffers is limited
via this parameter in order to prevent HP-Tx from being emptied completely.

No. of retries for 'URGE frame' <0-9>

[0]:

The number of times an urge frame will be retransmitted.

Terminal emulation (application) support

[Yes]:

Support for terminal emulation within the application. The valid values are Yes/No.

Health-check (application) support

[Yes]:

Support for health check within the application. The valid values are Yes/No.

MDLC Network Layer

Network Layer

System configuration stock size <1-50>

[1]:

Number of paths the Network layer is allowed to learn. This parameter is for future use. In
the current version, Network can learn only one path even if a different value is specified.

General Communication

Addr. range response for 'All RTU simulation' <Site ID +- Range> [0]:

Assigning alternate addresses to an RTU. If the basic address is X and the range is Y, then the
unit responds to all calls in the range of {X,X+1,...,X+Y}. If the range is -Y, the unit responds
to all calls in the range of {X-Y, X-Y+1, ..., X}.

This parameter is for field simulation in laboratory conditions and for the Dual CPU
mechanism.
