Chapter 7 Communication function
2) Introduction of transmission operation
User defined mode is normally operated when TX / RX frame list written via Frame Editor and TX / RX Function
Block of GMWIN program are agreed with each other.
[Figure7.2] Setting example of transmitted data
(a) Frame writing of Frame Editor
[Figure7.2] shows an example of writing Frame Editor and transmission Function Block of GMWIN program for
setting of transmission frame. If transmission frame is edited in Frame Editor, the frame name and the number of
transmitted data shall be written identically in SND_MSG(transmission Function Block) of GMWIN program for the
applied frame transmission. The frame written in Frame Editor takes the role of matching transmission protocol and
the transmission Function Block of GMWIN program takes the role of sending transmission data. Data set in
transmission Function Blocks of SD1~SD4 is transmitted as included in ARRAY area of the frame registered in
Frame Editor, thus transmission Function Blocks agreed with the number of transmission frames shall be written also
with the number of data and the frame name as exactly agreed in order to perform transmission.
