You can define 3 topics to organize your polling strategy. Each Topic can be enabled/disabled separately, have a Poll Rate and are linked to a
specific Device.
• Poll rate:
Is expressed in MilliSeconds and a default value of 2000 will be used if leaved empty.
• Global Device Address:
Have the following syntax: IP Address, Port, Link.
•
IP Address = address on your Ethernet network (i.e.: 10.0.0.50)
•
Port = value from 1 to 3 representing: 1 = Backplane, 2 = Channel A, 3 = Channel B
•
Link could be:
¤ Slot: representing the Slot on the Backplane (0=CPU)
¤ Node ID: value from 0 to 99 (for ControlNet and DH+)
¤ IP address
REM: In the case of using a ControlLogix as Gateway, the Device Address could be like following:
IP Address, Port, Link[, Port,Link][, Port,Link]…
6.9.3 Tag name convention
6.9.3.1 ValueName
ValueName follows the syntax below:
[PROGRAM:ProgName.]SymbolicTagName
• ProgName is the name of the program where the Tag is.
If no ProgName, the Tag is in the global scope (tag is controller type)
• SymbolicTagName:
• Symbol of the tag.
Only atomic type following are supported: BOOL, SINT, INT, FLOAT, DINT, BIT ARRAY
• Bit selection with <SymbolicTagName>/bit
where bit is the bit number (from 0 to 31)
ex: controlbit/4 read the bit 4 of the controlbit register
• TIMER, CONTROL, COUNTER predefined types with <SymbolicTagName>.acc (or ctl or pre)
ex: MyVar.acc read the counter of MyVar
• Element of a table
<Symbol_1>[idx_1].<Symbol_2>[idx_2].<Symbol_3>[idx_3].<Symbol>
With 3 index maximum.
ex: table1[2].subtable[6].element read data named 'element' on the index 6 of the 'sub table' from the index 2 of the 'table1'
• Element of a structure
<Symbol_1>.<Symbol_2>
ex: CounterObj.init read the 'init' part of the structure 'CounterObj'
