MODBUS.KEEPALIVE

Description

Enables or disables the ModbusModBus is a serial communications protocol and is now the most commonly available means of connecting industrial electronic devices. ModBus is often used to connect a supervisory computer with a remote terminal unit in supervisory control and data acquisition (SCADA) systems. Versions of the ModBus protocol exist for serial port and Ethernet (it is widely used with TCP/IP over Ethernet) keepalive fault.

AKD2G uses TCP keepalive to monitor the EthernetEthernet is a large, diverse family of frame-based computer networking technologies that operate at many speeds for local area networks (LANs) connection between the AKD2G and the HMI"Human-machine interfaces " Also known as computer-human interfaces (CHI), and formerly known as man-machine interfaces, they are usually employed to communicate with PLCs and other computers, such as entering and monitoring temperatures or pressures for further automated control or emergency response. If the connection is unexpectedly terminated, for example the cable is cut, the Modbus keepalive fault F7101 is generated.

0 = Disabled. The Modbus keepalive fault will not be generated.
1 = Enabled (default). The Modbus keepalive fault is generated and a fault occurs for both axes.

Example

The following stops the Modbus keepalive from being processed.
