Hello,
Thanks for your great library.
i'm working on project of motor controlling.
I can read data from controller but not update output byte[1].
here's a part of code :

          # Switch the motor ON

if (motor_off 1 and home_off: #conditions to switch on the step motor
eeipclient.o_t_iodata[1]= 2 # action to switch the motor ON and it's done
#time.sleep(4)
else: eeipclient.o_t_iodata[1]= 2

          # Homing

if motor_on and home_off:
eeipclient.o_t_iodata[1]= eeipclient.o_t_iodata[1] +16 #Action of motor homing
print(eeipclient.o_t_iodata[1]) # this data display 18 but the motor is not doing homing
else: eeipclient.o_t_iodata[1]= 2

I tried to add time sleep but it doesn't work.

Any suggestions to resolve this issue please.

Thank you in advance!
Alexis

Hi,
thanks for charing this great repo.

I went through the example file and found it a bit confusing.
I am trying to figure out why you use in the example the eeipclient.t_o_iodata[8] for the first byte and eeipclient.t_o_iodata[9] for the second byte. Should it not be eeipclient.t_o_iodata[16] to get the second byte ?
I also would like to know how to assign single Bits with your eeip solution.

Thanks!

I have set up two connections for implicit messaging. But i only get data from the connection i established first. The connection i establish second only delivers zeros. And it is the same if i swap the order of establishing the connections. Only the first established connection works properly. Is it possible to get data from to connections at the same time?

Hi,

I have Python3.9 installed. But when I run "python3.9 -m pip install eeip" I only get an error message
"ERROR: Could not find a version that satisfies the requirement eeip (from versions: none)
ERROR: No matching distribution found for eeip".

It does not seem like eeip exists on pip? Or why does this not work?

The sequence variable is defined here:

And goes through a 0 + 0 operation :

And is not touched anywhere else. This messes with OpENer here:
https://github.com/EIPStackGroup/OpENer/blob/5375e60e9d80a297db7ce47c4129e1a57c50b191/source/src/cip/cipioconnection.c#L922

Because it never thinks any new data is coming in.

Fix seems to be sequence += 1.
