Timing of writing recipe data and completion of writing
Writing recipe data to the PLC occurs in the following order:
1. The user or PLC sets the write recipe flag to ON (bit 0) and the recipe is
written into the PLC.
2. When writing is finished, the writing completed flag is automatically set to
ON (bit 8).
3. The user or the PLC sets the write recipe flag to OFF (bit 0).
4. The writing completed flag is automatically reset (bit 8).

Reading and deleting follow the same scheme. When several commands are given
simultaneously by setting the respective bits to ON in the control device, the operations will be
executed in the following order:
1. Writing
2. Reading
3. Deleting.
When writing, reading, and deleting are executed normally, the error flag is OFF, i.e. the error
code is 00(H).
