Operating principle
Depending on the state of the HMI device connected to the connection box, the F-FB
switches the outputs of the F_FB_KTP_RNG and prepares the output user data.
Each HMI device can take one of the following states on the connection box:
●
Logged off without communication error
The HMI device is successfully removed from the safety program of the F-CPU. This
ends PROFIsafe communication. The HMI device has no influence on the outputs of
F_FB_KTP_RNG.
●
Logged off without communication error
The actual operating mode of the HMI device on the connection box.
F_FB_KTP_RNG responds as follows:
–
The HMI device is supplied with user data, for example the ID of the connection box.
–
The output ENABLE is set according to the state of the acknowledgement button of
the HMI device.
The output E_STOP is set according to the state of the emergency stop button of the
HMI device.
–
If the operator wishes to disconnect the HMI device from the connection box, he must
log off the HMI device before disconnecting it from the safety program.
●
Logged on with communication error
PROFIsafe communication with the HMI device is resumed after a brief interruption,
enabling user data to be exchanged again between the HMI device and F CPU. As long
as the communication error in not acknowledged, F_FB_KTP_RNG behaves as follows:
–
The HMI device is supplied with user data, for example the ID of the connection box.
–
The outputs E_STOP and ENABLE return the value "0" regardless of the switch
position of the emergency stop button and the acknowledgment button.
Addresses of PII and PIQ
You can find the start address of the PII and PIQ in the PROFIsafe settings for the HMI
device.
