affect the effect of TPID. The value of the sampling time shall not be large, and
it needs to be smaller than the relay switching cycle time.
 Set 14 error descriptions for TPID, and see Table C-1 for details. If any of the
errors occurs, the system reports an operand error and does not perform TPID
operation.
 Sampling time ≤ 1 scan cycle, and data overflow and result overflow during
operation will lead to error alarm and stopping TPID operation.
 Initialize operands before performing the TPID command for the first time. If
operands change during operation, the underlying data of TPID will be updated
in the next cycle.
 Support up to 18 TPID commands to be executed in the same project
simultaneously, and an error will be reported if the number of commands
exceeds 18.
