One 4X register at the beginning of the 4X control register groups is read only which feeds back the status of
password control which was configured via Registers 62560 through 62598 (Security Mask Control Block) or via
the Communications Configuration Screen accessible through ECP or WinECP. The register lists the six control
blocks found in the TPU2000/TPU2000R. Table 5-41 lists the Security Mask register, which reports, which of the
control blocks require password control. A status of 1 in the defined bit location allows any value to be placed in
the password field (as shown in Table 5-42). The Security mask status of what was programmed through ECP,
WinECP or Modbus Registers 62560 through 62598 may be obtained by reading Register 41409. A status of 0 in
the defined field requires the correct password to be sent as part of the control process.
Figure 5-43 illustrates the Group Blocks within the TPU2000/TPU2000R and its associated typical control register
mapping.

One method to perform control through the Control Block is as follows:
• Write all registers other than the register associated with the “Execute Register”
•
Write a “1” to execute the control command.
