Hello LuisCtrl,
you speak about SAFEX-C.15? Please use the correct names, to be sure you get the right answer!
For example , to generate STO for the drives , how should I configure the PLC Outputs ?
- It depends on the drives you use. If an IndraDrive or a ctrlX DRIVE expects test pulses you apply OSSD to the 0.5 A outputs. See below for OSSD. BTW: OSSD means that cross circuit check is done by the output.
- If a drive wants his own test pulses applied to his inputs, you may use the relay outputs and bring the test pulses of the drive back to the drive's STO inputs.
- Test pulses are provided by the SAFEX-C.1x for input signals that are provided from passive elements, where the 24V source is provided from SAFEX-C.1x. Cross circuit check is done on the input side, where test pulse patterns are compared to the given Pulse 1 or Pulse 2.
And another question , in case I want to generate double channel OSSD Outputs (for external devices) , how should I condigure the PLC Outputs?
- OSSD is managed by the SIL-setting in the SAFEX-C.1x controller properties: SIL3 ==> all 0.5 A outputs are OSSD outputs, SIL2 ==> select OSSD or not inside the outputs individial properties.
I don't understand the PP/PN difference of swithcing and the pulses.
- PP- or P-Switching means that you are providing 24V for your actuator pole 1 and the pole 2 is connected to common GND. This is a single channel. You need to do the same for the second channel.
- PN means you are connecting the P of your output pair to pole 1 and the N to pole 2 of your actuator. In this case you have already a two-channel control, since you are switchting both poles. The PN capable outputs come with 2.0A and you can connect e.g. a door lock.
