Which would be more correct, to use "IMSTP" or "EES" to connect HMI signal R30-iB?

Hello friends!
I want to connect the physical Emergency stop button from the operator's workplace with HMI panel.
Initially, I thought to connect UI[1] (IMSTP), UI[2](Hold), UI[3](SFSPD) through the HMI and use the EES1 EES11 EES2 EES21 signals from E-STOP BOARD (figure 1) to connect the button (At the moment, there are just electrical jumpers on the E-STOP BOARD)

But after some thought, I began to doubt - maybe it's worth connecting only UI[1] (IMSTP) to the E-STOP button from physical robot output module (), instead of sending it via tcp/ip.

Is it safe enough? In this case, EES is not used.

Hi,

Imstp, Hold, Sfspd and Enable are not safety rated Inputs so should not be used with the safty circuit or as safety.

EES should be wired if you don't have a safety bus.

Thanks, the most confusing thing was that my paper manual says: "IMSTP - this signal determines an emergency stop controlled by the system".
As I understand it, these are different categories of ESTOP.

This has nothing to do with Emergency Stop.

From the R-30iB Plus manual:

All things related to machine safety (not meaning "do not injure the mechanical unit", but "do not injure humans") needs to be safety rated.

The UOP-signals are only "normal" digital signals, not safety signals.

I've already figured it out, thanks guys.
It is a translation error in the localized manual
