Group 2 Errors: Command Parsing Errors 

 

E020 Undefined 

String. 

Character string not identified as valid command, in position indicated by 
trailing argument. 

 

E021 Illegal 

Character. 

Character in string not a recognized character (A-Z, a-z, 0-9, "=", "?", ".", "+", 
"-", <SP> (space), <LF> (line feed), or <CR> (carriage return). 

 

E022 Illegal 

Operand. 

Keyword string followed by illegal operation (command, program, 
query). 

E.g

., TEMPST1 may only be queried; is a temperature which 

exists in the system and is measured. Attempt to program via 
TEMPST1= will yield E022. 

 

E023 

Question Mark (?) Followed by Argument. 

Query will not accept an argument. 

 

E024 

Value Too Long. 

Programmed value may not exceed 8 characters. 

 

E025 

Illegal Sign Placement or Excess Decimal Points. 

Polarity indication (+,-) must be first character. Only one decimal point 
permitted per number. 

 

E026 

Too Many Decimal Places. 

Too many digits supplied after decimal point. 

 

E027 

Value Out of Bounds. 

Programmed number exceeds limits fixed internally or by superseding 
limits (

e.g.,

 FSPANH will limit USPANH). 

 

E028 Excessive 

number. 

The previous filters will allow certain [illegal] ranges of numeric 
possibility to get through. This error traps these ranges before they 
cause software mathematics errors (due to register overflow, 

etc

.). 

 

Group 3: Security Errors 

 

E030 

Unit Not in Remote. 

Attempt has been made to program a value which may not be altered if 
system is presently switched to "local" operation. 

 

E031 

Not a User Function. 

Certain program statements are reserved for factory access. Error 31 reports 
an attempt to program values requiring [factory] security-code access.
