| The parameter is implemented only for TCP/IP-TCP and TCP/IP-TCP Redundant line categories. The parameter activates the disconnection of the TCP connection after the execution of each read cycle, or after the value is written. The parameter was implemented due to problems with connection stability on mobile GPRS networks. | YES/NO | NO | ||||||
| This parameter activates the eavesdropping mode. In this mode, requests are not sent and writing does not work. Only received packets are parsed. The nature of the Modbus protocol implies that it is necessary to eavesdrop on both the requests and responses of existing communication. | YES/NO | NO | ||||||
| Setting Tcp No Delay parameter to YES causes low-level socket option TCP_NODELAY to be set, thus turning off the default packet coalesce feature. The parameter is implemented only for TCP/IP-TCP and TCP/IP-TCP Redundant line categories. | YES/NO | NO |
