Yes, you are right! According to manual: The MOD_CLI and MOD_SERV blocks called in the MODBUSPN FB use the TCON and TDISCON blocks from the standard library to establish or terminate connections between the CPU and the communication partner. You can find required information in the folow manual: SIMATIC SIMATIC Modbus/TCP Communication via the integrated PN interface of the CPU |

Thanks! As I see, for redundant system I need to use other functions. |
