How to access the specified slave in a multi slaves bus ?

[jinyistudio534]

Hi,
Sorry to keep bothering you. 😅
I have 4 slaves on the ek1100. They are el1088, el1088, el2088, el2088 in order.
with your ethercat.py in the example. i can get 5 slaves.
I have two EL1088 and two EL2088 each. How should I write my program code to control them ? 😵
print("Number of terminals:", await master.count()) out = EL4104(master) await out.initialize(-2, 20)

I try it, OK 👍

import asyncio
from ebpfcat.ebpfcat import FastEtherCat, SyncGroup
from ebpfcat.devices import DigitalInput, DigitalOutput
from ebpfcat.terminals import EK1100
from ebpfcat.terminals import EL1088
from ebpfcat.terminals import EL2088

async def main():
master = FastEtherCat("eth0")
await master.connect()
print("Number of terminals:", await master.count())
out1 = EL2088(master)
await out1.initialize(-3,19)
out2 = EL2088(master)
await out2.initialize(-4,20)
do1 = DigitalOutput(out1.channel1) # use channel 1 of terminal "out"
do2 = DigitalOutput(out2.channel3) # use channel 1 of terminal "out"
sg = SyncGroup(master, [do1,do2]) # this sync group only contains one terminal
task = sg.start() # start operating the terminals
for i in range(100):
do1.value = 1 if do1.value==0 else 0
do2.value = 1 if do2.value==0 else 0
await asyncio.sleep(0.5)

task.cancel()  # stop the sync group
asyncio.run(main())
