Tag Reference

Tags are configured using the Device and Item parameters. The Device parameter indicates the address of a Controller on the S8000E network. If a Tag represents data coming from a main Controller, Head Of Cell, the Device parameter must be equal to 0 (zero). If a Tag represents direct data from a remote station, it must have the address of that remote station, as declared in the List of Remote Controllers option. The Item parameter indicates the address of a Tag and it is composed of the parts indicated next, separated by commas.

Address

Address of a variable inside an area. The size of an area depends on the allocation performed in ControCAD. The available options are described on the next table.

Address

ASig

For the Head of Cell Controller of models 8075 and 8035, values are allocated in linear addresses in Word format, such as "A,R32,0" (first Float), "A,R32,2" (second Float), and so on. For remote stations, addressing is always in Word format, considering the rule slot * 100 + position, such as "A,U16,1000" (input 0 of slot 10), "A,U16,1001" (input 1 of slot 10), or "A,U16,1101" (input 1 of slot 11)

BSig

For models 8075 and 8035, values are allocated in linear addresses per bit. For the Head of Cell Controller, values are allocated in continuous addresses starting from 0 (zero), such as "B,U8,123" (position 123). For remote stations, physical points are allocated continuously starting from address 0 (zero). Calculated points remain in their own area and users must add 2000 to the position, such as in address "B,U8,25" (position 25) the value must be equal to "B,U8,2003" (position 3, area TSX)

MSig

Allocated in linear addresses per byte. There is MSig only in the Head of Cell, such as M,U8,30 -> MSig 30

SP

Linear address that can have a U16 or R32 data type

COs

Open Loop Single pulse command. Does not use Tag's value to perform the command. It must have an U8 data type. Linear address starts at 0 (zero)

CCs

Closed Loop Single pulse command. Does not use Tag's value to perform the command. It must have an U8 data type. Linear address starts at 0 (zero)

COd

Open Loop double command. Uses the value of Tag 0 (zero) or 1 (one) to define which command to send. It must have an U8 data type. Linear address starts at 0 (zero)

CCd

Open Loop double command. Uses the value of Tag 0 (zero) or 1 (um) to define which command to send. It must have an U8 data type. Linear address starts at 0 (zero)
