【#29079(PR)】 Master Func. IO Addr. Area PLC side Device
Set the device to store the following data:
The data which stores the head address and size (in word form) of the master function receive and
transmit data used by each slave node.
00(HEX): Input data head address of the 1st slave node
01(HEX): Input data size (word count) of the 1st slave node
02(HEX): Output data head address of the 1st slave node
03(HEX): Output data size (word count) of the 1st slave node
04(HEX): Input data head address of the 2nd slave node
FB(HEX): Output data size (word count) of the 63rd slave node
---Setting range---
Within the number of device points set in the PC parameter's device setting.
【#29080(PR)】 Master Func. Receive Data Module side Transfer Cont.
Set a read word count of the data received from each slave node.
The standard setting is "256".
---Setting range---
1 to 256
【#29081(PR)】 Master Func. Receive Data PLC side 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.
<Example>
Slave node configuration
---Setting range---
Within the number of device points set in the PC parameter's device setting.
