The user-defined variables and I/O data of each slave are allocated as follows:
The user program accesses the slave with WORD-type variables.
When the user program accesses the slave only with BOOL type, use the BOOL-type user-defined vari-
ables
Slave1_OutData_B
defined in the example.
The user-defined variables and I/O data of each slave are allocated as follows:
The user program accesses the slave with BOOL-type variables.
When the user program accesses the slave with both WORD type and BOOL type, use the union-type
user-defined variables
Slave1_OutData_C
defined in the example.
The user-defined variables and I/O data of each slave are allocated as follows:
The user program accesses the slave with WORD-type or BOOL-type variables.
When you use the union, prepare the union data type Mem that you can access with WORD and BOOL
as shown below.
