Im using wago in one of my application



The Configuration is as below

750-841
PROGRAMMABLE FIELDBUS CONTROLLER
WAGO
750-430
8-CHANNEL DIGITAL INPUT MODULE, 24V DC
WAGO
750-530
8-CHANNEL DIGITAL OUTPUT MODULE, 24V DC
WAGO
750-455
4-CHANNEL ANALOG INPUT MODULE, 4-20mA
WAGO
750-650
Serial interface RS232
WAGO
750-600
END MODULE
WAGO





Im communicating with HMI on MODBUS RTU.

Now the problem im facing is as below.

My analog input address start from %IW2 to %IW5 ( im getting values)

Now when im forcing my digital input at address %IX6.0 (1st channel) chanel is energized but its not energizing my bit in software and same problem is with digital output.

My communication with HMI is also working.



Kindly send me the addresses for above configuration as soon as possible.

Regards
 
Hello!
Try to set bit %IX0.0 and you will be happy. Digital input start from %IX0.0 in HMI.
The same situation with digital output.
Analog input and output has the same address like in PLC.
What HMI you use?

Surely the Digital Inputs will start at %IX2.0, the RS232 module uses the first 4 bytes? Similarly for any Digital Output?

it depends on what type of serial card you have
it can be 4 bytes (2 words) or 6 3 words.
digital in should be in your setup starting with word 6
out should start with word 3
in simulator this will not work.
try for yourself to put first the serial port then the analog port and then the digital ones.
now in real is same as addresses.
 
use the markers they start at 12288 and use in your program to set the outputs according your markers.
this way you are independent of in/outputs.
