Chapter 4 General-Purpose Output Function - Mitsubishi Electric MELSEC-L02SCPU User Manual

CHAPTER 4
This function uses the built-in external output signals (8 points) as general-purpose outputs for external devices such
as lamps. By turning on/off the output device (Y0 to Y7) in programs, the LCPU can output the signals externally.
(1) Parameter setting
Set the output signals and error time output mode.

(2) External output timing
On/off status of the output device are refreshed to the external outputs (Y0 to YF) at execution of the END
instruction. Therefore, a delay for one scan (maximum) occurs from when an external device turns on/off in
programs until when the on/off status is refreshed to the external output.
(3) Direct output
When using the output device (Y0 to Y7) for the direct output device (DY0 to DY7), on/off status of the device are
refreshed to the external outputs by using the instruction such as the SET instruction.
(4) Partial refresh
The output device status (only specified range) is refreshed to the external output by executing partial refresh
using the RFS instruction to the output device (Y0 to Y7) ( MELSEC-Q/L Programming Manual (Common
Instruction)).
