Explanation
1. When the conditional contact switches from OFF to ON, the PLS instruction is executed, and the device D sends out
a pulse for a scan cycle.
2. Do not use the PLS instruction in function blocks.
3. ISPSoft V3.06.01 supports data type D and the BOOL type variable for declaration.
Example
When X0.0 is ON, M0 is ON for a pulse time. When M0 is ON, Y0.0 is set to ON.
