AS-i safe master

[Veganic 8]

Q series As-i master monitoring safety slaves. 0000 input pattern should equal not safe but I'm getting 0000 'blips' when safe. I have to use a timer to check that the input stays 0000 for 15ms. I guess I'm not getting data consistancy for some reason. Anyone know how the Asi master reads data and passes it to the PLC? Anyone have any other ideas? Ta.

Q AS-I master does NOT support AS-I Safety.

Of couse it does. It just doesn't do it very well. Edit : a quick look at the siemens forum seems to show that timers are used there so this may be the only way to do it. I was trying to get a record of which safety device went off in the cases where it is only momentarily off. Edited 4 Apr 2009 by Veganic

Do you have another safety-rated master on the network? Because the Q master does not support the safety feature, only regular I/O.

Yes.
