Safe I/O Module, Safety over IO-Link
IP67 Module

Linking PROFIsafe process data with program modules
12.2 Safe input
address range
82 english
The input data are located in the first two bytes of the PROFIsafe input user data. The table
below shows the assignment of the individual bits.
Note
Depending on the sensor analysis type single-channel (1oo1) or two-channel (1oo2)
for the safe input ports, the information sent for the corresponding ports will differ.
1oo1
Both input channels of the ports are sent individually.
Input port designation
Signal designation ( F-DI)
Pin No.
Telegram byte
Telegram bit
Bits 0, 1, 4 and 5 of byte 1 are not filled and always have a value of 0
3)
1oo2
The sent bits are the combined state of both input signals on a port.
Input port designation
Signal designation ( F-DI)
Pin No.
Telegram byte
Telegram bit
4) Bits 4, 5, 6 and 7 of byte 0 and bits 0, 1, 4, 5, 6 and 7 of byte 1 are not filled and always have a value of 0
Note
In sensor analysis 1oo2 (two-channel equivalent) the value of the combined input
value corresponds to the status of safe input channel F-DI 1.
Ensure that the combined input value fulfill the requirements for basic safety principles
(acc. ISO 13849-1/-2) in your application.

Note
The errors resulting as per the table (see above) are detected by the safe I/O module.
