Operation when a long timer or long retentive timer device is
used
When the data to be handled exceeds the width (32 bits) of the current value, the long timer or long retentive timer operates
by using not only the area of the current value but also the areas of the previous value, contact, and coil.
When the BMOV instruction is used to batch-transfer current values, current values alone cannot be batch-transferred. Batch-
transfer the current values, contacts, and coils altogether and, after the batch transfer is finished, use only the current values.
When the DMOV instruction is used to batch-transfer current values, repeat the transfer of the current values alone using the
FOR to NEXT instruction.
To batch-transfer the current values of the timer device
When the BMOV instruction is used, only current values are batch-transferred.
