NI PXI-2593 Multiplex switch module

Code word for selection of the same frame function for block processing. END; Code word for leaving the frame function NEDA. NEMO contains the following instructions for the definition, output, correction and deletion of a function block.  The object length of a program generated under NEMO is limited to 32 Kbyte. Function algorithm Definition: block for function algorithm D,type,PROGRAM; type: Type name; names which are illegal in NEMO as well as special characters and symbols must not be used (see Chapter 10.7.1).  Only permissible in authorization level 3 of the process operation keyboard.

Formatting the output log of a user function 

 Only permissible in authorization level 3 of the process operation keyboard. Once an instruction has been inserted into a program page, the rest, starting at this instruction, is written on a new page. Frequent insertion of instructions results in the number of program pages becoming far greater than actually necessary. The instruction “FO;“ compresses the output log of a program into full pages, i.e. superfluous PAGE commands are eliminated.A compilation with signalling of any program errors is only carried out following the instruction “AE;” if a modification has been made in the selected program. If no modifications have been made, or if the output is on a printer

If programming errors are detected

 it may be necessary to enter “F;” to display the NEMO final log if the screen is full. Even if “F;” is not requested, its input is accepted following “DE;” or “AE;” without execution and without an error message. If an error is signalled in a TML program (PROGRAM, CHECK, PROBLEM) following termination of the programming with “DE;” or “AE;”, the system automatically adds a “RETURN;” and a “PAGE;” to the start of the program. The execution of a faulty program is thus prevented. The inserted instructions are signalled as error F 522 in line 4 following a further syntax check if the program contains a TAKE or GIVE instruction. Following correction of the TML program, the automatically inserted instructions must be deleted by the command “LS,2;”
