Figure 5-45. Typical Modbus/Modbus Plus Register Definition
During the commissioning process, it is required that the correct data is mapped from the relay to the host device.
The conventional method is to have an individual with expensive test gear to apply individual voltages and
currents to the relay terminals to simulate field conditions. The individual must be at the substation and a direct
link must be made to the individual at the host device verifying the correct data is being received and interpreted
correctly.
With 6X memory and some of the 4X memory, a host device can force the read/write capable 4X and 6X memory
locations and verify data is sent and received to some memory location. The SCADA REDI® provides much
more flexibility allowing streamlining of the commissioning process.
Within the TPU2000 and TPU2000R control register memory map a single bit (Bit 13 in Register 41415) may be
set to allow READ, WRITE, and READ/WRITE Modbus/Modbus Plus commands to be sent to the previously
READ ONLY memory locations. A typical scenario is illustrated in Figures 5-44 and 5-45.
