    Hi there

    Is it possible that one of you can assist my on the following plc problem:

    I must create a ladder logic program that will cause four lights to flash sequentially.The sequence of the order should be:
    When the system is started 000001 is on immediately for one second and the switches off.Then 000002 is on for one second and then switches off.then 000003 and 000004 do the some as output 1 and 2 ,then the process automatically begins again.A pushbutton 100001 (n/c in the field ) starts the process.A pushbutton 100002(n/o) stops the process
    No emergency stop and overload is required.

    Thanx in advance
    Heinrich

    Are you looking for a program? If so, for what?
