E1100 Ethernet Comms

[GCR 0]

Hi All Does anyone know is it possible to connect an E1100 HMI to 4 separate PLC's each having a QJ71E71 card installed?? In E-Designer it only shows 2 TCP/IP connections in the network connections. Does this mean an E1100 can only connect to 2 PLC's Via Ethernet. Regards,

Hi, Yes, it's possible to connect an E1000-terminal to several QJ71E71. I think that you have mixed up some things though. There are two tcp/ip connections in the peripherals. TCP/IP connection 1 is connected to the network card and TCP/IP Connection 2 is placed under unused functions (this connection can be used if you want to connect to the terminal using a serial/modem PPP-connection). If you right click on driver 1 (Q Ethernet) and select properties then a settings dialog will appear on the screen. Here you can assign a defualt IP-address (for 1 of the QJ71E71). So if you add e.g an analog numeric and connect it to D0 the driver will read D0 from the assigned IP-address. If you want to address D0 in another PLC/QJ71E71 then the syntax is like this: 101:D0 where 101 is the last octett in the IP-address. Example: Terminal's IP-address 192.168.98.1 Default IP-address: 192.168.98.100 Read D0 from 192.168.98.100, is addressed D0 Read D0 from 192.168.98.101, is addressed 101:D0 Read D0 from 192.168.98.102, is addressed 102:D0 It's also possible to index which IP-address that you want to read from, e.g I1:D0. If the value in I1 = 200 then you will read D0 from 192.168.98.200. Let us know if you need more help... //Supporter
