Modbus Plus Global Register Mapping (37 Registers Defined) TPU2000R Only

Modbus Plus has the unique protocol characteristic that up to 32 registers of data may be attached to the token
and seen by all the nodes on the Modbus Plus Network. The register configuration can be done through ECP or
WinECP or via Modbus Plus. Global Mapping requires that the Modbus/Modbus Plus TPU2000 Register Address
from 40001 Through 40921 (The read only defined registers) may be mapped to the GLOBAL REGISTER
MAPPING TABLE. The leading 4X is deleted from the required register mapped to the block. An Example is
shown in Figure 5-70. The register definitions for configuring Global Data are shown in Table 5-81 below.
Additionally, a security mask configuration register has been included within the configuration block. If the bit of
Register 62598 assigned to the function is set to a 0. Then a password must be used when controlling a function
in Groups 1 through Groups 6 as described in Section 5. The status of control being password
protected/unprotected is indicated in Register 4XXXX. If a password section is unprotected, then the password
requested in Groups 1 through 6 may be any arbitrary value corresponding to the bit state.
If one were to configure the global registers via ECP or WinECP, a configuration screen is available to
parameterize each of the 32 global Modbus Plus registers. An example of the global register configuration screen
is shown in Figures 5-70 below. If a Modbus Plus TPU2000R capable relay was configured (Model # 588
XXXX6- XXXX4 or 588 XXXX7-XXXX4), the following screen would be shown on WinECP. Note the Global
Register Tab (accessed from the "SETTINGS" menu header) is visible and available as an option.

Option
Depressing the Global Register Configuration tab allows the screen shown in Figure 5-71 to be visible. The
Global Register Access screen and the Write Control Block (which is Register 4XXXX, reference the section TPU
CONTROL FUNCTIONALITY for a complete description). Depress the SET GLOBAL REGISTERS pushbutton to
access the register configuration screen.
