Commands
•Frame Division Method
If the command length is longer than 266 characters, divide the data into separate frames before send-
ing, as follows:
Frame Division Method
1. Divide the data into frames each with 266 characters max.
2. Use the final terminator (* CR) for the last frame (frame n) only. Use the delimiter (CR) at the end of
other frames.
3. Be sure to include the command code, data setting, processing area number setting, and start address
in the first frame (frame 1). If any of these parameters is omitted, a command input error will occur. The
write data can be omitted.
4. Make sure that data is divided correctly without any single frames containing AA*CR or XZ*CR.
