Extended Modbus Variables
The registers shown in this section are intended for advanced integration solutions, where the user desires full
control of the system by the PLC. For optimal communication latency, it is recommended that only the registers
which will be monitored and changed on a regular basis be mapped and the remaining parameters be configured
with the display.
