V5 (2) Data memory starting system

The data memory starting system is the system which starts the SEND/RECEIVE functions without using exclusive instructions. Set the target station number, data memory address, etc. on the specified data memory (communication information storage area).

You can increase the amount of data to be transferred in one SEND/RECEIVE operation using multiple connected channels.

For cases using 1 channel alone, maximum 256 bytes

For cases using 2 connected channels, maximum 512 bytes For cases using 3 connected channels, maximum 768 bytes For cases using 4 connected channels, maximum 1024 bytes

Set these channel connections on the parameter (address 007700 to 007703(8)). (See page 9·27 and 48)

[Setting the contents in a communication information storage area]

In order to assign a communication information storage area (64 bytes), set the top address on the parameter (address 007710 to 007713(8)).
