Hi All,

I am new to PLC's (ok, programmable relays)

I have a couple of questions in relation to the Logo.

Question 1: Does the siemens logo have similar functionality to the Mitsubishi AL2-10MR-D. I need to replace the Mitsubishi unit with a 12vdc product and the siemens came to mind.

Programming question:

I have 2 inputs (input-A and input-B) and also has 2 outputs (output-A and output-B) Depending on which order the input-A or input-B are triggered (within a defined period say 1-sec), will determine which output A or B generates a pulse. Can someone give me a hint on how to approach this task with the siemens logo.

TIA

Peter

Never seen such a function in the Logo. Perhaps you could write it in code?

Hii
You can put one timer of 1 sec say T1.If T1 is ON then take one NO contact of the timer and your digital input in series and output it to a through pulse output coil
