6.1 Error Messages of PLC Compiler
The error messages of the PLC compiler and the codes are interpreted as follows.
In the case of a flawless compilation of the PLC program, the PLC compiler returns the
message "PASSED" (flawless compilation).
If the PLC compiler detects a syntactic error in any phase of the compilation, the process of
compilation is interrupted and a message (with a numeric identifier) is return. In the case of
an error the cursor is pointing at the erratic instruction.
Error messages of PASS1 are:
ERROR 1 - module number over :200 in the PLC program
ERROR 2 - the ASCII source program is larger than the space reserved for it
ERROR 3 - the generated ASSEMBLY program is larger than the space reserved for it
ERROR 4 - too many CALL or JUMP instructions are in the PLC program
ERROR 5 - no :000 module in the PLC program
ERROR 6 - no :001 module in the PLC program
ERROR 8 - no module label found in the PLC program
ERROR 9 - a parameter other than a decimal or octal number encountered in the instruction
concerned
ERROR 10 - a parameter other than a hexadecimal number encountered in the instruction
concerned
ERROR 11 - no ending bracket ")" is found - the opened conditional test group is not
terminated
ERROR 12 - single quotation mark (") - the opened spring-print instruction is not
terminated
ERROR 13 - "N" followed by illegal character (Nxnnn)
ERROR 14 - "NL" followed by illegal character (NLxnn)
ERROR 15 - "NS" followed by illegal character (NSxnn)
ERROR 16 - non-decimal number or subscript in the instruction concerned
ERROR 17 - not terminated conditional test, no Z found
ERROR 18 - no conditional test following a bracket, illegal character within brackets
ERROR 19 - no logic relation within brackets - [A or X or O]
ERROR 20 - illegal instruction within brackets
ERROR 21 - blank string, no meaningful character within the quotation marks
ERROR 22 - illegal instruction "SRPnnn" - writing the parameter memory is illegal
ERROR 23 - illegal character behind instruction "SRxnnn" or "LRxnnn"
ERROR 24 - more than 15 steps in leftward shift
ERROR 25 - more than 15 steps in rightward shift
ERROR 26 - "B" followed by illegal character (BIN, BCD)

ERROR 28 - "BC" followed by illegal character (BCD)
ERROR 29 - CLx followed by illegal character (other than "S")
ERROR 30 - "S" is followed by illegal character in the STORE instruction
ERROR 31 - relation symbol "<" is followed by an illegal character (other than L, S or a
