Refresh command:
Use CANFLS command to refresh (if there are RW attributes, the master will write to
the slave station; if there are RO attributes, the slave station will return the read values
to the master); M1066 will be 1 if refresh has been completed; M1067 will be 1 if
refresh is successful, and M1067 will be 0 if an error has occurred.
NOTE
When using CANRX, CANTX or CANFLS, internal implementation commands will wait until
M1066 is completed before executing the next CANRX, CANTX or CANFLS.
Afterwards, download program to the driver (Please note that the PLC's default
communications format is ASCII 7N2 9600, and the station number is 2. The WPL must
therefore be modified, and the WPL setting pathway is settings > communications
settings)
Step 5: Set the slave stations' station numbers and communications speed
Slave station no. 1: Pr.09-37 = 0 (Speed 1M) Pr.09-36=10 (Node ID 10)
Slave station no. 2: Pr.09-37 = 0 (Speed 1M) Pr.09-36=10 (Node ID 11)
Step 6: Connect hardware wiring
When performing wiring, note the head and tail terminal resistance; connection methods are
as follows:
Terminal
resistor
Terminal
resistor
Step 7: Initiate control
After a program has been written and downloaded, switch the PLC mode to Run. Merely
turn power to master and slave stations off and then on again.
