【#29081(PR)】 Master Func. Receive Data PLC side Device
Master function receive data read device
Set the device to read the data received from each slave node.
<Data configuration>
The data is aligned at the word boundaries of the slave nodes before stored.
Double-word data is stored in the order of lower word first and higher word next.
If there is an odd number of byte input modules, one byte of empty area will be inserted for
alignment at the word boundary. Bit input modules are treated in the same way as the byte
input modules.
---Setting range---
Within the number of device points set in the PC parameter's device setting.
【#29082(PR)】 Master Func. Transmit Data Module side Transfer Cont.
Master function transmit data write word count
Set a write word count of the data which is transmitted to each slave node.
The standard setting is "256".
---Setting range---
1 to 256
