Will need to control 30 relays preferably “directly” through Ignition and I’m wondering if anyone has done similar and can provide assistance/ideas?
Considering something like the Ethernet relay module from Numato https://numato.com/docs/32-channel-ethernet-relay-module/
Numato supplies commands that can be used via telnet for control. Before buying this or another unit, I am wondering about using Python from Ignition (possibly referencing some functions in a package) and use the Python Telnet client library to send commands. Also wondering if I could just use the scripting function system.util.excecute?
Does anyone have experience with this, or perhaps a completely different solution that you can share?
