Description

Common ASDU Address

✔

✔

Enter a value for the common address of an ASDU.

  • The value scope is 1...65535.

  • 65535 is the broadcast address.

  • The default value is 3.

NOTE: Common ASDU address is configurable from Channel Configuration > Device Configuration screen.

Cyclic Message Interval (ms)

✔

Enter a value for the number of milliseconds between cyclic updates.

  • The value scope is 1...4294967295.

  • The default value is 10000.

Cyclic First Period (ms)

✔
Enter a value for the period to generate the first cyclic data response.

  • The value scope is 1...4294937295.

  • The default value is 500.

Background Period (ms)

✔

Enter a value for the period allowed to generate background scan data on a particular sector.

  • The value scope is 1...4294967295.

  • The default value is 20000.

Read Time Format

✔

Select the completeness time format for responding to C_RD_NA from the drop-down list:

  • None

  • CP24 only for IEC60870-5-101

  • CP56

The default value is None.

C_RD_NA Measure and Time Format

✔

Select the time stamp format in the response to read command from the drop-down list:

  • None

  • CP24 only for IEC60870-5-101

  • CP56

NOTE:

  • This field is used for measured points.

  • The default value is None.

C_IC_NA Time Format

✔

Select the time stamp format in the response to read command from the drop-down list:

  • None

  • CP24 only for IEC60870-5-101

  • CP56

NOTE:

  • This field is used for counters.

  • The default value is None.
NOTE: When the module receives a C_RD command, it responds to the information object with the requested information-object address (IOA). When multiple data points have the same IOA, the module returns the first information object according to this priority: M_SP, M_DP, M_ST, M_BO, M_ME_A, M_ME_B, M_ME_C, P_ME_A, P_ME_B, P_ME_C, CUSTOM_M_IT_D. Consider these points when you configure IEC60870-5-104 server communications.

Description

Select Timeout (ms)

✔

Enter a value for the period after which a previously received selection is timed out. Confirm that an executed command is received before the time-out in order to be valid.
