Appendix A Modbus Activation
The SS2000+ has a Modbus interface to easily interface with Industrial Control Systems.
Modbus TCP is used to provide activations into an SS2000+ for specific warning
announcements across an industrial plant. Users can activate the system using the
SS2000+ or industrial control systems can activate the hotkeys.
The software version listed below is the minimum version that support the Modbus
interface. A firmware upgrade is required to use the Modbus interface if the RTU firmware
is below these minimum requirements.

activating digital voice messages (address 1) or tones (address 2) the attenuation values
(address 4,5) must be set after the unit is armed.
Activating digital voice (address 1) and tone (address 2) clears the activation status. Unit

Commander (v15.6.0.3+). Commander reports Last Activation fault.
