IEC60870_SEND_DISABLE

IEC60870_SEND_DISABLE can be used to disable sending any data packages from a IEC 60870 station.

No data will be send in monitored direction on an active link any more if IEC60870_SEND_DISABLE has been executed with inputs EN=TRUE and ACTIVE=FALSE.

To select the IEC60870 connection on which no data will be sent any more, the connection needs to be specified on input CON. On the SEND_DISABLED connection no inquiries will be answered with data any more. The normal ACT_CON, ACT_TERM for an inquiry will be still answered to fulfill the normal command state machine. The sending of data can be enabled any time by executing the IEC60870_SEND_DISABLE function block with EN=TRUE, CON=<desired connection> and ACTIVE=TRUE any time. From that point in time data will be send again in monitored direction. This also applies for inquiries, read requests and background scan data.
