Notes on communication
NOTICE
Communication errors caused by address conflict
Communication errors can occur if several devices in a network share the same bus
address or IP address.
Make sure that your HMI device is assigned a unique address in the network.
Note
Updating tag values following a communication error
If communication between an HMI device and PLC is interrupted, all tag values displayed on
the HMI device will be replaced by a hash mark ("#").
When the communication between the HMI device and PLC is restored, all tag values will be
updated immediately. The cycle time for updating the tag values begins again at "0."
