7 MEMORY CONFIGURATION AND DATA PROCESS
(7) Reading data from buffer memory to peripheral device ( )
The following transmission processes are carried o ut with the [Read from
module] from the peripheral device.
1) The "parameters", "positioning data (No. 1 to 600)" and "block start data (No.
7000 to 7004)" in the buffer memory area are transmitte d to th e pe ri p he ral
device via the PLC CPU.
The following transmission processes are carried out with the [monitor] from the
peripheral device.
2) The "monitor data" in the buffer memory area is transmitted to the peripheral
device via the PLC CPU.
(8) Writing data from peripheral device to buffer memory ( )
The following transmission processes are carried out with the [Write to module]
from the peripheral device.
1) The "parameters", "positioning data (No. 1 to 600)" and "block start data (No.
7000 to 7004)" in the peripheral device area transmitted to th e buffe r me mory
via the PLC CPU.
At this time, when [Flash ROM write] is set with the peripheral device, the
transmission processes indicated with the following are carr ied out.
