7. The RSTD instruction can implement the command action on only one drive or slave every
time. If multiple RSTD instructions are enabled simultaneously, the PLC will automatically
take priority to perform the instruction which is enabled earlier.
8. The RSTD instruction is executed to send the command when it is enabled. If the instruction
is disabled before the Ok flag is on, the PLC will not set the Ok flag to ON.
9. Apart from notifying the specified drive to clear the error state, the instruction would also
re-check if relevant communication parameter values are correct and re-set correct
communication parameter values.
For example, due to the disconnection of the slave of station address 2, the entire system
stops running. After the trouble is solved, the slave of station address 2 can return to the
state of being controllable by using the RSTD instruction to reset the slave of station address
2 only. So the time of re-initializing all drives are saved.
10. If the slave responds by sending back any communication command fault to the PLC during
the communication, the RSTD instruction will turn the Err flag on and stop the upcoming
actions. (Refer to explanation of D6001 for error codes.)
