Ac900F hardware error (hardware module error out of input memory )
Greetings
I do have an AC900F control station with a total number of 1040 I/O
configured as the following:
. 616 DI
. 384 AI
. 40 DI
All the AI had been configured as Pt 100 2 wire
when I do apply this station to the control builder F I do have the following error massage:
[Hardware module "PROF_1_C1" Error :out of input memory (3584):7808. Reduce number of salves and/or max number of inputs bytes]
I do try to change to number of I/O bytes per slave in the module configuration , but error not solved
kindly advice
what is the cause of such error?
what is the solution?
Best Regards

In CBF > HW Tree > Profibus master (@ position C1) > Parameterisation mask > second tab > Number of I/O bytes per slave change Max. no or input bytes according to your configuration, Check image below( in your case it may be CI 930F)
Or reduce the slaves by changing highest bus address to maximum numbers of slave devices you have configured under that profibus master.
you need to optimise between max number of slaves and I/O bytes. or optimise your configuration for slave addresses i.e try to reduce or bring down highest bus address.

How do yo declare your I/O?? Do you use DTM or GSD ??
above answer will solve the error , good luck

Correction
the I/O List is the following :
.161DI
.384AI
.40DC (instead of DI)
