OPERATION
3.4 Programming
The master unit handles this unit as a slave device (T7EC1, T7ECT1 for 16-point output, T7EC2,
T7ECT2 for 32-point output).
There are two types of data: The PDO (Process Data Objects) output data sent from the master unit
to a slave device (in case of this product; 16-point output, 32-point output) and the input data sent
from the slave device to the master unit. This product is an output device that receives output data
from the master unit and outputs to the valve (no input data).
Refer to the instruction manual issued by the PLC manufacturer when programming.
Refer to the following table to program the I/O mapping.
The setting made to specify which action to take on the output in the event of an error, which is a
unique function of this slave unit. This output status setting does not affect the program.
