Figure 5-64. Function 20 Read 6x Register Frame Definition

Figure 5-65. Modbus Command 21 - Write General Reference Format
IMPLEMENTATION TIP - When 6x Registers Are Written, A 10 Minute Execute Timer Is Initiated Upon The First
Write To A 6x Block. If The Execute Register Is Not Written With A Value Of 1 Within The 10 Minutes Of The
Initial Write, The 6x Veiwable Register Segment Will Be Restored To The Original Values From The
"TPU2000/TPU2000R's" Internal Flash Ram Memory.

Programmable Input Configuration

The TPU2000/TPU2000R allows for query or changing of Relay Configuration Data via the Modbus ASCII
protocol. Table 23 further describes the register assignment for viewing or changing the TPU2000/TPU2000R
parameters.

Term Definitions

The parameterization may be configured via ECP or WinECP. However changing the Programmable Input
Configuration is slightly more involved through Modbus Plus or Modbus. A few terms must be understood before
discussing the procedure for changing the 6X memory Programmable Input parameters.
