POINT 
 
The dedicated instructions used for reading/writing the buffer memory of the 
intelligent function module on a remote I/O station (REMTO and REMFR) are the 
execution type for which several scans are needed.  Therefore, transmissions of 
the execution results are not synchronized with the I/O signal operations.  When 
reading a digital output value on an A/D converter module after changing the 
operating condition during operation, be sure to read the A/D conversion completed 
flag (buffer memory address 10) at the same time. 
Also, for the case of changing the operating condition, insert an interlock to prevent 
the execution of the REMFR instruction.
