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 27

- "BI" followed by illegal character (BIN)

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
