HMI-to-CPU communication
The CPU supports Ethernet communication
connections to HMIs.
Note
The CPU models CPU CR20s, CPU CR30s, CPU CR40s, and CPU CR60s have no
Ethernet port and do not support any functions related to the use of Ethernet
communications.
The following requirements must be considered when setting up communications between
CPUs and HMIs:
●
Configuration/Setup:
–
The CPU must be configured with an IP address.
–
The HMI must be setup and configured to connect with the IP address of the CPU.
–
No Ethernet switch is required for one-to-one communications; an Ethernet switch is
required for more than two devices in a network.
Note
The rack-mounted CSM1277 4-port Ethernet switch can be used to connect your CPUs
and HMI devices. The Ethernet port on the CPU does not contain an Ethernet switching
device.
●
Supported functions:
–
The HMI can read/write data to the CPU.
–
Messages can be triggered, based upon information retrieved from the CPU.
–
