Function change depending on the version
The function of this instruction changes depending on the version as shown in the table below.
Error
An operation error occurs in the following case. The error flag M8067 turns ON, and the error code is stored
in D8067.
1) When a device specified in or is outside the allowable range (error code: K6705)
Program examples
1. Program examples 1
In the program example below, the current value of the high speed counter C235 is compared in each
operation cycle, and then the output Y000 is set to ON if the current value is "K500" or more (when the current
value of C235 is not cleared.)
2. Program examples 2
In the program example below, the current value of C235 is transferred to D201 and D200, and the current
value of C235 is cleared when X001 turns from OFF to ON.
