8.7 Extended File Register Operation Instruction

Processing details
The current value of the extended file register (ER) stored into the SD memory card is read for (n) points to the file register (R)
in the CPU built-in memory specified with (s).
The normal or abnormal completion of the ERREAD instruction can be confirmed with the instruction completion device (d)
specified with the setting data.
• Instruction completion device (d)+0: Turns off when the ERREAD instruction is activated, and turns on during the instruction
processing for the scan in which the ERREAD instruction has completed normally.
• Instruction completion device (d)+1: Turns off when the ERREAD instruction is activated, and turns on during the instruction
processing for the scan in which the ERREAD instruction has completed abnormally.
Also, when the ERREAD instruction has completed normally/abnormally, instruction execution complete flag (SM8029) and
instruction execution abnormal end flag (SM8329) turn on only for one scan at the same timing with the instruction completion
device (d). After the contact of the ERREAD instruction turns on, the extended file register (ER) access flag (SM9366) turns
on during access to the extended file register.
• When (s)=0 (R0), and (n)=0 (the number of read points: 0) are specified, all the points (32768 points) of the
extended file register (ER) are read to the file register (R) in the CPU built-in memory in a batch.
• When (s)=1 or higher (R1 or later), (n)=0 (the number of read points: 0) are specified, ER(s) to ER32767 are
read to the file register (R) in the CPU built-in memory.
