Example: RUNA READ
The following example illustrates the data movement of the RUNA READ instruction. The data movement of the STPA
READ is the same as the RUNA READ instruction.
Example: RUNA WRITE without Repeat
The following example illustrates the data movement of the RUNA WRITE instruction without repeat designation. The

Example: RUNA WRITE with Repeat
The following example illustrates the data movement of the RUNA WRITE instruction with repeat designation. The data
movement of the STPA WRITE is the same as the RUNA WRITE instruction.
While input I0 is on, data of 5 bytes is read from
the area starting at address 1 in intelligent mod-
ule 1 and stored to the 5-byte area in data regis-
ters starting at D9.
Status code is stored in data register D100.
