If an execute command is not written to the register block within 15 seconds after parameters have been
configured in the block, the block will be reset and the entire configuration sequence must be re-initiated.
Another method to perform control through the Control Block is to write individual registers to the desired control
Group block and then write "1" to the execute register within 15 seconds after all the writes have been completed.
Groups I through VI share commonality in that an operation type must be written to the Execute Register
(Register 41410 in Group I [INITIATE INPUT], 41416 in Group II [FORCE PHYSICAL INPUT], 41423 in Group III
[FORCE PHYSICAL OUTPUT], 41430 in Group IV [FORCE LOGICAL INPUT], 41440 in Group V [SET RESET
OUTPUTS] , and 41457 in Group VI [PULSE OUTPUTS]).
Writing a value of 0 to the execute register voids a control execution of the function. Writing a Value of 1 to the
execute register allows the function to operate if the consecutive registers are parameterized correctly.
A correct Password may have to be written to the block for the desired function to execute (Registers 41411 and
41412 in Group I [INITIATE INPUT], 41417 and 41418 in Group II FORCE PHYSICAL INPUT], 41424 and 41425
in Group III [FORCE PHYSICAL OUTPUT], 41431 and 41432 in Group IV [FORCE LOGICAL INPUT], 41441 and
41442 in Group V [SET RESET OUTPUTS], and 41453 and 41454 in Group VI [PULSE OUTPUTS]). The ABB
TPU2000/TPU2000R contains a default password of four spaces. If Appendix B is consulted, the ASCII code for
a space is 20 (HEX). Thus the numerical value to be sent to the registers corresponding to the default password
is 2020 (HEX) for password register 1 and 2020 (HEX) for password register 2.
IMPLEMENTATION TIP – if control does not occur after initiation through the network, verify that the local/remote
control bit is not configured in the programmable logical inputs logic or that the local/remote control bit is in the
remote state. If the local/remote control bit is configured, and the control switch is in the local position (indicating
that control via the network is inhibited), if one of the control commands are sent via the network, a modbus
exception response shall be sent to the host rejecting the command. If the local/ remote control bit is not
configured, control may take place via the operator interface panel (MMI) or via the network contemporaneously.
Additionally, modbus Registers 40172 through 40175, if read using modbus code "03" shall indicate the nature of
the communication control errors of the last control function.
