an old plc(omron cpu13) was broken, and it was replaced (same plc program backup) but can not recover the link with parker hmi ts8010.
Nothing in hmi was updated never, because it has been working fine. the comm. protocol is Omron MAster FINS through ethernet, PLC performs all functions well but
hmi can't "see" nothing and the display is used to check all temperatures and alarms.
i ping plc(it is ok), ping hmi( it is ok too), So ethernet cables and ip are ok. Is there any thing else I need to do ?
