Explanation of function and operation
This function block sets to ON a device specified in
keeps ON the device specified in
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) Expression of function blocks in each language
*1. Set the instance when using a function block.
Describe the instance name when programming a function block.
Error
1) When an output number is specified in
indexing, M8316 (I/O inexistence error) turns ON.
(Applicable to the FX
2) When a device (M, T or C) other than I/O number is specified in
does not exist due to indexing, an operation error (Error code: 6706) occurs.
