Network Interface

The network interface on the Interface Module allows basic Run/Stop commands and internal status data and
can be communicated to and from the HarmonicGuard Active filter. The HMI display implements an
integrated ModbusRTU slave device for the network interface (see the HMI Display Connection section) or
an optional network communications gateway can be used such as Ethernet/IP to implement other protocols
(see Appendix).

The input/output register maps of the data available from the network interface are available in Table 7.18
and Table 7.19. All input and output registers are two bytes in size. For the base address of the input and
output data sections please reference the connection sections in this manual specific to the configured
protocol. For the integrated ModbusRTU network interface reference the HMI Display Connection section. If
an option Communications Gateway is configured reference the appendix.

The network Run/Stop command allows a remote network to send a run command to the HarmonicGuard
Active filter. The network command input will only be acknowledged if the Relay Run/Stop Enable is set to
ENABLED on the HMI Display setup screen. Pressing stop locally via the HMI Display will set the enable
for the Relay Run/Stop Enable to DISABLED.
