(2) MELSAP-L program description
The MELSAP-L describes step programs in the following format:
Instruction
Example of MELSAP-L
format
Example of list format Example of circuit symbol
Output (o) oY70 OUT Y70
Y70
High speed timer (h) hT0 K100 OUTH T0 K100
T0
H K100
Set (s) sM100 SET M100
SET M100
Reset (r) rM200 RST M200
RST M200
The instructions other than
above (o, h, s, r) are the
same as the list.
MOV K100 D0 MOV K100 D0
MOV K100 D0
To arrange several operation outputs in parallel in the same step, separate them with ","
(comma).

(3) Precautions on description
(a) Describe the instructions which do not require execution conditions (e.g. DI or EI) at the last
of each operation output.
With the MELSAP-L, execution conditions like contacts cannot be created as the operation
output. Therefore, the instruction which requires execution conditions cannot be created
after the instruction which exists individually and does not require execution conditions.

(b) Up to 24 instructions can be described for one operation output.
POINT
• The timer continues measurement while the step is active.
• The instruction which requires execution conditions cannot be created between FOR and
NEXT instructions.
