S5 S flags? | PLCS. net - Interactive Q A The early S5's, 150u's and 115u's only had F flags, not sure if early 135u's were any different When 155u's came out they had bigger memory (150u's were restricted to 48K ), so Siemens created another flag memory area which expanded the flags available, the S flags They couldn't expand the the original flag area beyond the 256 bytes, can't remember why Long time, at least 10 years since I

Safety PLC for dummies | PLCtalk - Interactive Q A safety plc's are in different (yellow) colour jokes aside, as once i read: "while PLC will try run production even if a failure occurs somewhere, safety plc shut it down in a safe way " safety plc consist of 2 cpu, one is for normal plc tasks while other is for safety program it also consist of special safety I O besides normal that continuously check themselves internally against failure
Safety PLC and PNOZ in S7 F CPU | PLCS. net - Interactive Q A You will need to post a diagram showing how you intend to combine a single channel e-stop with a dual channel e-stop If an S7 F-CPU stops then all program execution stops and the F outputs go to their fail safe state The safety program is called (normally) from OB35 like any other block call
Motor SF with VFDs | PLCtalk - Interactive Q A It's pretty hard, in my view, to equate a nameplate service factor at 60hz with anything else a motor does at speeds other than 60Hz At 60hz, on PWM power, the motor will run hotter, all other things being equal, than on sine wave power For this reason, normally the service factor, regardless of the nameplate value, is considered to be 1 0
s-curve math? | PLCtalk - Interactive Q A S curve Maths frac = time ramp_time; f= (3-2*frac)*frac*frac; This is easiest method to plot the S curve as per your solution I want to know How this formula has been derived constants 3 2 derived from ? what is frac= is factorial? f is frequency? why it is multilpied 2 times frac
