During the HMI build time the tag database has to be created from the UNITY PLC variable database.
A link between Unity XVM le and Vijeo Designer project has to be done. As Vijeo Designer variables
do not access Unity structured and unlocated variables, it is necessary to recreate structured datatypes.
These structure data types allow us to use generic popups using indexed physical addresses.

Connetion to the gateway b
The ATS48 and TeSys-T are connected to the Ethernet network via an ETG100 gateway. Communication is
transparent between the Ethernet and Modbus serial line therefore the I/O scanning service can directly access
the device data. To congure this gateway, an Internet browser is connected with.

Note:
The I/O scanner sends several questions in parallel while the gateway sequences them one by one. Therefore,
if a Modbus unit does not respond to a fault for example, this will generate a time-out at the gateway which will
take precedence over the time-out of the I/O scanner. The result is that a Modbus unit with failed communication
can trigger the time-out of the I/O scanner for the other Modbus equipment. To minimize this, it is necessary to
set a minimum time-out (0.5s) on the serial port of the gateway.
