you send  this payload = b"\x00\x00\x04\x50\x00\x00\xff\xff\xf0\x30\x00\x20\x01\x30\x00\x00"
to ports 2001, and or 2002, to the subnet's broadcast address. Now your opto22 devices will respond to pings.

# Here I made this function
def discover_targets(ip):
    # pass Broadcast addresses.
    DISCOVERY_PORTS = (2002, 2001)
    payload = b"\x00\x00\x04\x50\x00\x00\xff\xff\xf0\x30\x00\x20\x01\x30\x00\x00"
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    for port in DISCOVERY_PORTS:
        s.sendto(payload, (ip, port))
    s.close()
