Hi
I am trying to I/O mapping and cannot connect KR outputs with Fieldbus Profinet Safety outputs.
For inputs worked .
with TIA portal I succeeded to connect the profinet network between PLC and KRC4, in same range of KRC4 IP address 172.31.1.147 KRC4 and 172.31.1.148 PLC
the safety inputs and outputs on S7-1200F CPU need any wiring or is just an internal comunication that close them on byte 0 and 1?
Is needed any function block defining?
i have added also SM1226 F inputs module
is not about how to cheat but to understand Profisafe PLC versus X11.
I have also Input module bought already, so it will be used for different safe inputs like e-stop, closed gate, red light....
I mentioned only E-stop because principle is same . A switch circuit that close or interrupt a 24V signal.
Thank you both for clarifying.
Yes, that is correct. If you have ProfiSafe, then no Safety I/O hardware modules are required between the KRC4 and the Safety PLC. X11 and X13 are replaced by ProfiSafe signals.
That I want to understand.
Having Profinet and Profisafe, no I/O module needed as SM 1226 input or output.
Only the Safety PLC S7-1200F.
This PLC to replace X11, what settings need be made with TIA portal?
Those for Safety functions via Profisafe regarding input byte 0 and byte 1?
imagine that I care about human life and of course exists fenced working space, external emergency button that stop both robot and spindle. Operator is instructed and is the only person nearby robot.Acces in the area is forbiden. All programs before real running are simulated in CAM software. If anything wrong, collisions,.... are corrected before send it be executed. And I never seen a robot to move randomly by itself.
Src program is checked therfore.
Spindle as any other CNC machine cannot save you if u put your hand on tool .In that case, yes is dangerous. But people working with CNC machine are instructed and they have to respect rules.
I know what I have to do .
Spindle manufacturer put some sensors on spindle which are connected as Inputs to protect eventually wrong tool clamping, situation when motor do not start or stop.
There are protective controlling measures , except if you want harm yourself.
Can you please to point my previous posting?
Thank you
on the robot side assigned safety IO functionality is fixed - you cannot change it.
so if this does not work for your application, you need the PLC (or whatever safety controller you are using) to be flexible here....
What I understood so far, on my Profinet Controller KRC4, having ProfinetController/Device 3.2 installed and no X11 safety interface, to make robot moving except in Startup Mode, where I was able to move it, I need a Safety Siemens CPU fail safe and input safety module , to be able to close circuits as in X 11 standalone diagram. Here I was using only to add external emergency button.
To be able in my KRC4 Profinet to close similar those signals as in X11, I have to set inputs byte 0 and byte 1 .They should be setted as active to have close circuits.
Also here external emergency button can be setted , when is pressed robot to stop
I do not use any Safe Operation even software is installed.I don't need monitoring.
You can have standard outputs on your EtherCat interface (EK1100+EL2xxx or whatever).
but if they need to be enabled by safety, your PLC will need a safety output module.
my ethercat don't need to be enabled by safety, neither power.
I feed with 24 VDC from controller, and EL 2xxxx output commands from src program external inverter, electrovalves, pneumatics.
I also used EL1xxxx to control robot for example, if no holder in spindle, to not allow spindle start.
At this moment I need to have a safety interface to allow me robot moving.
For this scope I need aside S7-1200 fail safe, SM 1226 input safety and an SM1226 output safety module as hardware to close safety Profisafe, similar with X11 interface?
but, KRC4 has Profinet 3.2 installed, therefore should have Profisafe since tgere is no X11 interface.
That is why I got Fail Safe plc, Safety input....to use them instead X11
what safety output module do you consider suitable for S7-1200F , aside to SM 1226 input Profisafe? 6ES7226-6BA32-0XB0
Similar SM1226 has only 4 outputs.Are they enough for safety Profisafe(replace of X11)
6ES7226-6DA32-0XB0
For the rest of I/O commands , spindle start/stop, pneumatic, electrovalves....etc will use EK1100 Ethercat .
btw, you are likely to need some safety outputs as well.
is indeed outputs module needed too?
You cannot add 3.2 under Profinet like this. wrong configuration.
Everything is ok so far.
Thank you, I solved yes logged as safety maintenance, now in Start Up mode robot moves
A small step ahead.
I wait for PLC S7 1200 F with SM1 input module .
Any help to set it in TIA Portal will be useful.
What Skyfire said, to close signals that not being used, and to set E-stop signal
on safety configuration activation
X311 jumper is there on CCU.
I tried before and now again Start Up Mode, and cannot move, driver don't enable.
I only added EK1100 , wired at 24 VDC and added A-X44 ethernet cable.
Rest of all is as it came.
ProfiSafe replaces X11. As such, the Safety PLC must be programmed to replace the X11 signals. Signals that are not being used must still be "closed" by the PLC Safety program -- this is the equivalent of using jumper wires between pins on the X11 to satisfy the unused Safety signals. Just like X11, any signal that is not closed is treated as open/unsafe by the KRC.
This is what I need in fact, equivalency for X11 jumpers done with PLC , and external emergency stop activation.
First you say "E-Stop button programming is not a problem" but then ask about PLC enabling the safety circuit. This is not consistent.
I just wanted to say would not be a problem to configure in the PLC.
Controller type is KRC4 8.3 SDA
KRC4 controller SC4.1-TDA4.1 X217 which has Profinet Controller/Device 3.2
Attached info from AM.INI
the E-stop button programming is not a problem, I am asking if PLC has to be programmed to be able to enable robot safety circuit RDC, KRC, Smartpad....and all starting cycle to enable robot move
I cannot imagine that a new kuka KRC4 Profinet is not able to be used without suplementary hardware to add such this PLC, software, ....and head ache.....
While X 11 variant is so easy to use.
And the Siemens S7 1200 F with input module, need to be programmed?
I understood that in PlC will be copied the gdsml file from robot, but this is enough or need a program to instal in PLC?
Is needed TIA portal?
Is not a free software and not worths to buy only for one plc configuring.
Siemens guy told me could help me but need to give him the program , what the plc need to do.
Therefore, to well understand S7-1220F CPU , 6ES7215-1AF40-0XB0 is ok being the PLC, but the input module should be 6ES7226-6BA32-0XB0 profisafe digital input?
They ca be coupled together for Safety.
I attached each data pdf for PLC and input module both rated fail safe.
As I read if not this PLC connected the robot won't move, being the safety interface for Profinet/Profisafe controllers KRC4.
Then the PLC must be configured with TIA portal for E-stop inputs.
I ordered a Siemens S7 1200F failsafe and an input digital module SB1221
The PLC comunication with KRC is Ethernet, but what slot is used in controller?
