Enable IEC60870 communication, specify your CASDU (common address of ASDU), and make additional optional settings.
- Use IEC60870: Use this toggle switch to enable the IEC60870 function.
- Expert mode: Use this switch to display additional settings.
Originator address: Enter the originator address of the controlled station. Default: 0
Server port: Enter the TCP port number of your communication. Default: 2404
Polling time: The FP-I4C unit collects the data from the PLC's IEC60870 library buffer. If IEC60870 is the main feature of your application, we recommend that you specify a very short polling interval, e.g. 5ms.
- Structured CASDU
Use this toggle switch to enter a two-byte address.
You can enter an asterisk ("*") for one of the two bytes (sub node) if the sub node is managed by the PLC.
- Show CASDU address in HEX: If Structured CASDU is enabled, the CASDU can be represented by hex values from 0x00 to 0xff for each byte of the address.
- CASDU address: Enter your common address of ASDU.
- Close IEC60870 connection if PLC is not running: If enabled, the FP-I4C unit reads the PLC status and closes all IEC60870 connections when the PLC is in stop mode.
