【#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
【#29083(PR)】 Master Func. Transmit Data PLC side Device
Set the device which stores the data to be transmitted to 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.
<Example>
Slave node configuration
---Setting range---
Within the number of device points set in the PC parameter's device setting.
【#29084(PR)】 Slave Func. Receive Data Module side Transfer Cont.
Slave function receive data read word count
Set a read word count of the data received from the master node.
The standard setting is "64".
---Setting range---
1 to 64
