I am trying to learn how to introduce values to a PLC trough python ModBus module what I'm currently trying to do is just to read the value of coil 1 to check if its True or false so I am using
order_ready = client.read_coils(0, 1)
print(order_ready)
and I get this as response ReadBitResponse(8) how can I get a "True" value from reading a coil
You can access the individual coils from the response ReadCoilResponse
using the bits
property . More on response could be found here
order_ready = client.read_coils(0, 1)
if not order_ready.isError():
#response.bits would return a list (multiple of 8) of booleans each bit representing the output of one coils
# In your case accessing 1st element should give the actual value
order_ready = order_ready.bits[0]
else:
# Handle error
