Send controlword

Hello again, guys,
I was wondering how to send the control word. I know about the transmission in the configuration file through cia402, but I need to send a specific value for the control word, not just set up the connection between them. Can you tell me where the signals are generated in LinuxCNC so that I can send a specific value? If I turn on the machine with a button, why doesn't the control word value change? Please explain to me not where the signals are sent, but how to send a specific value to the control word. Where in Linux are these signals generated, and how can I set them up for a specific driver? At what point do I need to inform Linux that the driver should use the control word 0Fh? I need to insert 0Fh into 6040, but it doesn't seem to work. I have the following pieces of code written:
sodick.hal:

#from cia402 to servo(ethercat)
net 4-controlword              cia402.4.controlword => lcec.0.4.cia-controlword

ethercat-conf.xml:

      <syncManager idx="2" dir="out">
        <pdo idx="1600">
          <pdoEntry idx="6040" subIdx="00" bitLen="16" halPin="cia-controlword" halType="u32"/>

you probably need to modify cia402.comp and somehow allow you to set the controlword from hal (probably from another pin)
What are you trying to do? 

I need to pass a specific value of the control word, but the pin cannot be written from .hal and I need to solve a problem with recording a value, I can't figure out where it comes from

What value does statusword have?
Look in the manual what that means. That is what prevents cia402 component to ask the drive to enable.
The drive will not enable until that condition is sorted out. Even if you write F to the drive it will reject it until status is fixed.
