The API for managing gateways and scanning the network was introduced with CODESYS V3.5 SP8.

Here some example code:

\# Find device object
found = projects.primary.find('Device', False)
assert(found and len(found) == 1, 'No or more than one device found')
dev = found[0]
\# Find gateway
gw = online.gateways['Gateway-1']
\# Scan network
targets = gw.perform_network_scan()
\# Find the target in the result list
matchingTarget = None
for target in targets:
   print("Name: {} Addr: {}".format(target.device_name, target.address))
   if target.device_name == 'KELLERMANB':
      matchingTarget = target;
      break
\# Set comm. path of the device
if matchingTarget:
   print('Set communication path of device')
   dev.set_gateway_and_device_name(gw, target.device_name)
   # or
   # dev.set_gateway_and_address(gw, target.address)
else:
   print('No matching target found')

Look for IScriptGateway, IScriptGateways and IScriptScanTargetDescription in the ScriptEngine API documentation.

Hello,

I have a question: How can i scan the network by Python? Because the project can not be login after network scanned . (CoDeSys version: SP9)

Thanks!
