IP67 IO-Link Modules for EtherNet/IP
5. I/O Data mapping
I/O messaging
HarshIO module supports up to a maximum of 8 I/O connections. Fewer connections allow faster data I/O
update rates (RPI value).
I/O Connections:
- HarshIO module supports 2 transport Class 1 I/O connections (Cyclic and Change-Of-State
triggers):
o 1x Exclusive Owner
▪ Unicast or Multicast (TO) connection
▪ Unicast (OT) connection
o 7x Listen Only or Input Only (8 Input Only connection if no Exclusive Owner connection)
