78 MOVILINK® Interfaces
Example 1:
Interface 1 is connected to 3 MOVILINK
configured as slaves with addresses 1, 2 and 3.
Output status:
PD1
PD1 (invalid)
The PLC writes user data PD1 ... PD3 and slave address 1 to the output process
image. The interface is in initialization status (status byte = 63).
Step 1:
PD1
PD1 (invalid)
By setting the flow control, cyclic transmission of the MOVILINK
permitted.
Step 2:
PD1
PD1 (valid)
Slave 1 has responded correctly. The slave address is written from the module to
byte 7 of the input process image. Setting the status byte (return code 1, "No
error") shows that there is valid MOVILINK
input process image.
