Programming the PLC main program
Programming of the PLC main program is described earlier in this manual
beginning from page 63. For a system with two drives, program similar function
blocks for both drives. In this case, main program for both drives is programmed
inside actions, this is done to achieve more clear presentation of the program.
Note: Name every function block uniquely, otherwise the program will not work
correctly.
A list of the Local variables is shown below.
