Precautions for dedicated instructions (common)
■

Do not change any data (such as control data) until execution of the dedicated instruction is completed.
■
When the dedicated instruction is not completed
Check whether the mode of the Simple Motion module is online.
A dedicated instruction cannot be executed when the mode is offline.
■
When using the safety program
Dedicated instructions cannot be used in safety programs.
■
When using the REMFR or REMTO instructions
When using the REMFR or REMTO instructions, configure an interlock with the following module labels.
• "Data link error status of own station" (SB0049)
• "Data link status of each station" (SW00B0 to SW00B7) of the target station
Check that the data link status is normal. ("Data link error status of own station" (SB0049) and "Data link status of each
station" (SW00B0 to SW00B7) of the target station are off.)
Precautions for link dedicated instructions
The following describes precautions when executing multiple link dedicated instructions simultaneously.
■
Channel of the link dedicated instructions
When executing multiple link dedicated instructions simultaneously, check that the channels for the instructions are not
duplicated. Link dedicated instructions with the same channel cannot be executed simultaneously. To use the same channel
for multiple link dedicated instructions, configure an interlock so that a instruction is executed after completion of another.
