Configuring Tags of an Elipse Software Application |
Developers of Elipse Software applications must create PLC or Block Tags to allow user access to local Modbus registers, dynamically allocated in this Driver's internal memory. These local Modbus registers are exclusive for each Slave ID. The size of Block Tags, the number of Elements, depends on the number of Modbus registers to read or write and the data type used in the Block Tag.
