When defining a variable through the variable editor/list, some data must be defined for the variables. In the following items, those data will be presented according to the group the variable belongs to.
Local and Local Retentive:
| • | Tag: variable identification |
| • | Size: number of elements of the array* related to the variable |
| • | Data Type: variable numeric type |
| • | Initial Value: value that will be loaded for variable during the initialization of the equipment |
| • | Comment: comment of the variable in the selected language |
Constant:
| • | Tag: variable identification |
| • | Data Type: variable numeric type |
| • | Value: constant value of the variable |
| • | Comment: comment of the variable in the selected language |
Global and Global Retentive:
| • | Tag: variable identification |
| • | Size: number of elements of the array* related to the variable |
| • | Data Type: variable numeric type |
| • | At: defines which global memory area the variable accesses |
| • | Address: address related to the global memory area. If not configured (empty), the compiler will automatically define its address. |
| • | Bit: for Boolean data type, it is necessary to define the bit it accesses (0...7) |
| • | Initial Value: value that will be loaded for variable during the initialization of the equipment |
| • | Comment: comment of the variable in the selected language |
| • | Modbus: modbus address |
System:
| • | Tag: variable identification |
| • | Data Type: variable numeric type |
| • | At: defines which global memory area the variable accesses |
| • | Address: address related to the global memory area. |
| • | Bit: for Boolean data type, it is necessary to define the bit it accesses (0...7) |
| • | Comment: comment of the variable in the selected language |
| • | Modbus: modbus address |
Global Parameter:
| • | Tag: variable identification |
| • | Data Type: variable numeric type |
| • | At: defines which global memory area the variable accesses |
| • | Address: address related to the global memory area. |
| • | Initial Value: initial standard value |
| • | Comment: comment of the variable in the selected language |
| • | Modbus: modbus address |
I/O:
| • | Tag: variable identification |
| • | Size: number of elements of the array* related to the variable |
| • | Data Type: variable numeric type |
| • | At: defines which global memory area the variable accesses |
| • | Address: address related to the global memory area. |
| • | Bit: for Boolean data type, it is necessary to define the bit it accesses (0...7) |
| • | Comment: comment of the variable in the selected language |
| • | Modbus: modbus address |
|
NOTE! When size is greater than zero, the variables are accessed in the Ladder through their array index. |
