Error Code
(EC1)
03
Meaning
Device specification error
04 Out of setpoint range
08 Parameter error An illegal paraeter is set.
Parameter number where error occurred (HEX)
This is the number of a parameter in sequence that first resulted in error when
counted from the leading parameter.
Example:
Error in device name specification
STX 01010BRW 05 I0017, 1, I0018, 0, A00502
Parameter numbers 1 2 3 4 5 6
In this case, EC1 = 03 and EC2 = 06
05 Out of data number range
For error codes other than those noted as EC1, there is no EC2 meaning.
