CHAPTER 6 COMMUNICATION FUNCTION
6-15
The functions of each registration item in Figure 6.21 are as follows :
- Area : to set the area to read the data to send when sending and to set the area to save
the received data when receiving.
- Size : the size of data to send/receive. The unit for sending/receiving is 1byte.
It is available to set 1Kbyte for G3/4/6L-PUEA and 7Kbytes for G3/4/6L-PUEB. G7L-PBEA
slave module is available to set 64bytes for sending and 64bytes for receiving,
respectively.
Point
1) The size of sending/receiving area is total I/O contact number that is created in
SyCon.
2) G4L-PUEA 1EA and GPL-TR2A(16points), GPL-TR4A(32points), GPL-
D22A(16points) are created in order and if setting the sending area
with %MW0 and the receiving area with %MW100,
* Sending area: %MW0
* Receiving area: %MW100
* Sending area size: 6 bytes (total output contact number)
* Receiving area size: 2 bytes (total input contact number)
* %MW0 data -> output by GPL-TR2A
* %MW1 ~ %MW2 data -> output by GPL-TR4A
* GPL-D22A input -> saved in %MW100
3)
The created order in SyCon is prior to station no. or cable connection when
sending/receiving the data.
