Ethernet Remote Master Hardware Configuration
Use a PC equipped with a 10/100BaseT or a 10BaseFL network adapter card and the
Ethernet Remote Master (ERM) Workbench software configuration utility (included with the
ERM manual, H24-ERM-M) to configure the ERM module and its slaves over the Ethernet
remote I/O network.
When networking ERMs with other Ethernet devices, we recommend that a dedicated
Ethernet remote I/O network be used for the ERM and its slaves. While Ethernet networks
can handle an extremely large number of data transactions, and normally very quickly, heavy
Ethernet traffic can adversely affect the reliability of the slave I/O and the speed of the I/O
network. Keep ERM networks, multiple ERM networks and ECOM/office networks isolated
from one another.
Once the ERM remote I/O network is configured and running, the PC can be removed from
the network.
