5.14.2.2 Global Device Address
The device address is either appended to the ValueName in the Item Name definition, or entered in the Topic global address fields.
The device address syntax is the following:
EH[,[[ipaddress,TCP|UDP,port]|[station]][,LUMP]]
Important:
If the PLC address is defined at the Topic level, it can be omitted in the Tag definition. In that case the Tag name will only contain
the "ValueName".
If the PLC address is specified at the Topic level, it will replace any address defined Tag by Tag.
EH Serial
EH,station
station : address of the PLC on the network
EH,4 the eWON will access PLC number 4.
EH
By configuration, an HITACHI PLC could have an undefined station number.
If this PLC is alone on a serial link, you don’t need to specify a station number.
EH,station,LUMP
station : address of the PLC on the network
LUMP : Link Unit Port Module
EH,4,FFFF0000 the eWON will access PLC number 4 with the LUMP FFFF0000.
EH,LUMP
By configuration, an HITACHI PLC could have an undefined station number.
If this PLC is alone on a serial link, you don’t need to specify a station number.
LUMP : Link Unit Port Module
EH,FFFF0000 the eWON will access PLC with the LUMP FFFF0000.
EH ethernet
EH,ipaddress,TCP|UDP,port
ipaddress : IP address of the PLC
TCP|UDP : select the protocol used
port : IP port used
EH,10.0.120.203,TCP,3004 the eWON will access the PLC at 10.0.120.203 with protocol
TCP and port 3004
EH,ipaddress,TCP|UDP,port,LUMP
ipaddress : IP address of the PLC
TCP|UDP : select the protocol used
port : IP port used
LUMP : Link Unit Port Module
EH,10.0.120.203,TCP,3004,FFFF0000
the eWON will access the PLC at 10.0.120.203, protocol TCP, port 3004
and LUMP FFFF0000
