ST_IEC870_5_101AcquisitionParams

From product version:

• TwinCAT PLC Library IEC60870-5-104 controlling station v1.0.0 and higher;
• TwinCAT PLC Library IEC60870-5-101 controlling station v1.0.1 and higher.

Configuration parameters for cyclic data acquisition. The initialisation sequence commands configured in the arrInitSeq array are executed once after receipt of M_EI_NA_1 (end of initialisation) or after the connection is established. The cyclic commands configured via the structure parameters testCmd, clockSync, arrGenro, arrCoro or genCmd are then executed.

arrInitSeq: Initialisation sequence. The initialisation sequence is always executed once after receipt of M_EI_NA_1 (end of initialisation) or after the connection is established.

testCmd: Parameter for cyclic test commands. Default: One test command every 60 seconds.

clockSync: Parameter for cyclic time synchronization commands. Default: Time synchronisation every 60 s.

arrGenro: Parameter for cyclic station query commands. Station queries for up to 17 datapoint groups may be configured. Default: One station query from the 'General' group every 60 s.

arrCoro: Parameter for cyclic counter query commands. Counter queries for up to 5 counter groups may be configured. Default: One counter query from the 'General' group every 60 s.

genCmd: Parameter for cyclic transmission of data points in controlling direction (single-commands, double-commands, setpoint-commands and so forth). Default: Execute all commands every 60 minutes.

delayCmd: Parameter for delay commands. Execution delay time of the next initialization step command. Default: Delay time = 5 s.

eAODBType: Application database type. This parameter defines how the data points are stored in the application database.

Example in ST:

In the following program section cyclic data acquisition is configured as follows: All initialisation steps are deactivated. The cyclic test command and time synchronisation command are also deactivated. In addition to the standard station query a further station query from group 1 is configured (every 100 s). In addition to the standard counter query, a counter query (freezing) from counter group 1 is configured (every 200 s).
