Omron CJ1W-ECT21 Operation Manual page 69

The example below uses the following data types:
• Slave_OutData_C (union)
• Slave_InData_C (union)
When you use the union, prepare the union data type Mem that you can access with WORD and BOOL
as shown below.
Use one of the data types or multiple data types shown in the examples to create user-defined vari-
ables according to the user program.
When the user program accesses the I/O data only with WORD type, use the WORD-type user-defined
variables Slave_OutData_A and Slave_InData_A defined in the example.
The user-defined variables and I/O data of the EtherCAT Slave Unit are allocated as follows:
I/O data
OUT slave I/O data (Output001)
OUT slave I/O data (Output100)
IN slave I/O data (Input001)
IN slave I/O data (Input100)
The user program accesses the I/O data with WORD-type variables.
When the user program accesses the I/O data only with BOOL type, use the BOOL-type user-defined
variables Slave_OutData_B and Slave_InData_B defined in the example. The user-defined variables
and I/O data of the EtherCAT Slave Unit are allocated as follows:
I/O data
Output001, Bit 0
Output001, Bit 1
Output100, Bit 15
Input001, Bit 0
