Wago 750-453 Fieldbus Independent I/O Module 750-453 Ficha De Dados

•  11 

The analog input module 750-453 transmits 16-bit measured values and 
8 optional status bits per channel. 

The digitalized measured value is transmitted in a data word (16 bits) as input 
byte 0 (low) and input byte 1 (high) into the process image of the coupler / 
controller. 
This value is represented with a 12 bit resolution on bit B3 ... B14. 
The status information included in the three least significant bits (B0 ... B2) 
can be parsed in the event of an error. 
Bit B0 = 1 is set when the range of measurement is overranged. 
Bit B2 is not defined and not evaluated. Therefore, they are represented with a 
‘X‘ in the table. 

Some fieldbus systems can process input channel status information by means 
of a status byte. 
This status byte can be displayed via the starting tool WAGO-I/O-CHECK 2.  

However, processing via the coupler / controller is optional, which means that 
accessing or parsing the status information depends on the fieldbus system. 

 

Attention 
The representation of the process data of some I/O modules or their variations 
in the process image depends on the fieldbus coupler/-controller used. Please 
take this information as well as the particular design of the respective 
control/status bytes from the section "Fieldbus Specific Design of the Process 
Data" included in the description concerning the process image of the 
corresponding coupler/controller.
