Chapter 8 Communication Functions
8-41
Example 1) [NUL] , [ENQ] , [1] , [A] : Possible Example 2) NUL, ENQ , [12] , [ABC] : impossible
- It is allowed to be only 3 consecutive characters.
Example 3) [ENQ][STX][NUL] : Possible Example 4) [A][NUL][ENQ][STX] : impossible
• Send / Receive
- Not defined : It is the initial value that doesn’t declare a frame format.
- Send : It is that declares send frame.
- Receive : It is that declares receive frame.
- When Frame 0 window is activated, Tx/Rx term is set as “Not defined,” and all the segments are not in
activation.
• Segment (1-8): Enter segment by segment to separate fixed sending data area (CONSTANT) and device
area (Array).
Item Contents
To set a segment type, there’re NONE (not defined), CONST (fixed data
area), ARRAY (Device area). CONST declares commands and fixed data
that are used for communication frame and ARRAY is used to input and save
the data needed for interactive communication. ARRAY type must be always
set by byte.
This field is to declare commands and fixed data that will be used in communication
frame and constant data to be declared by inputting. ASCII input must be done
within 10 characters and hex within 20 characters. If the number exceeds the limit,
set the next segment as the same type and continue to input there. As an
dedicated protocol communication, 10RSB06%MW10006 is a frame to execute
reading 6 word data from M100 at the slave station no. 16.
Ex1) 10RSB06%MW10006
If the segment is declared as ARRAY type, designate transmitting device (P,M,L,K,
F,T,C,D) and number of transmitting. The unit is byte
Ex2) If you want to transmit D000 ~ D003, the setting is as below.
(transmitting device : D000 , number of transmitting : 6 bytes)
