8 INSTRUCTIONS FOR DATA LINK
8.3 Refresh Device Write/Read Instructions
• The contents of the data stored in the area starting from (S1) are as indicated below.
• Instruction execution possibility of an execution type for each program.
• To write data to a refresh device, the data reflection to the station number specified by the instruction is executed at the
timing for the auto refresh.
• Number of points specified in n2 is written from the device specified in (S2) to the offset specified in (S1)+2 of the refresh
device assigned for the device specified in (S1)+1 of the target station specified in n1 and (S1)+0.
• At the above configuration, number of points specified in n2 is written from the device specified in (S2) to the offset (Y1078)
specified in (S1)+2 of the device assigned for the station number 4.
