Hi Guys,
I've not used one of these PLCs for a while so am a little rusty, but a customer has one on an old machine that he needs help with.
I can get online and upload/download no problem through the DH485 port however there is an HMI that's usually connected to this port and the machine will not run without this being connected up.
I'm therefore wondering if it's possible to 'online monitor' this PLC whilst the machine is running, maybe via the CPUs spare RS232 port?
Thanks in advance!
