beginner in mitsubishi plc

[Guest clair]

Hi! Me and my frinds are going to do a project in our plc education. We have six LED´s in our Mitsubishi PLC. Now we want the first one to flash once every second in 10 seconds. Then the second one will do the same thing and so on. Very thankfull for your help! //Clair

There will always be more than one approach to something like this. You can use multiples of timer, counters etc or use the inbuilt timing relays which are available in all mitsubishi PLC's. If you are using 6 ouptuts, the temptation is to use lots of interlocked timers, which can lead to confusion. One solution is to use only one timer and use comparison instructions e.g. T0 --]/[-----------------------(T0 K100) 10 second timer --[>= T0 K0]--[<= T0 K10]-------(Y0) Turns on Y0 for 1 second out of 10 --[>= T0 K11]--[<= T0 K20]-------(Y1) Etc... --[>= T0 K21]--[<= T0 K30]-------(Y2) --[>= T0 K31]--[<= T0 K40]-------(Y3) --[>= T0 K41]--[<=T0 K50]-------(Y4) --[>= T0 K51]--[<=T0 K60]-------(Y5) As I say, there is always more than one way..... Hope it helps!
