Note (1) The access times for FileWrite and FileRead commands indicate Memo- ry Card access times.
(2)The access times in the tables above are standard times when the PLC Setup's "Fixed Peripheral Servicing Time" setting is set to the default val- ue of 4% of the cycle time.
(3)The attached file transfer time can be reduced by increasing the time al- lowed for peripheral servicing in the PLC Setup's "Fixed Peripheral Ser- vicing Time" setting.
