IV – 5. Specific codes

IV – 5. 1. SP code as an instruction

For its use, see chapter III – 2. page 23.

Accessible using the

key :

Syntax : SP nn L00 (to 99)

After an SP request (instruction), the operands requested are :

 a number from 00 to 99.

 A label number, corresponding to a return step indicator and a suffix indicating the order in

which the subroutines are performed. When an SP is called up with a return label L00, you

will return back to the step following the one where the SP was called.

Note : When one subroutine calls another subroutine, only 3 overlapping levels are possible.

IV – 5. 2. PLC code as an instruction

The PLC is a programmable logic controller which can be associated with a main program if necessary.

Its functions are described in the Programming Manual Level 2. See example in chapter V – 1. page

53.

Syntax : PLC 00 (to 98)

Note : The number 00 means that there is no PLC associated with the main program.

IV – 5. 3. SR code as an instruction

For its use, see chapter III – 3. page 26.

Accessible using

then :

Syntax : SR 01 (to 99)

Note : . SR 00 is not valid, it is implicit (executed by default).

. When an SR is executed, it returns to the last Rnn Label with the same number as

itself.

Example : SR 05 returns to the last R05 encountered before its execution.
