Schneider sr3 b262bd syntax

4 posts in this topic

Hi,

I've never worked on this range of PLC before, and am trying to make sense of the program currently loaded.

Using the manual I have most of it worked out, but there is one aspect I can't find reference to at all. Why are some of the timer references in inverse text? e.g.

M1----T1----T3-----t4----------------[M2

Thanks in advance

It is a normally closed contact of Timer4

Thanks for replying.

I get that for t4 (same for any contact, lower case is NC. upper case is NO), but it is T1 that I don't understand. Some timers have the designation in normal font, some in inverse (white on black). Just wanted to know what the difference is.

Is this when you are online with the zelio? if so isnt it just indicating that the timer coil is on?

If this is not the case maybe its indicating that the timer has been activated and is busy timing but the coil is not yet switched on?

I dont see the same behavior on my zelio soft
