STEP  BY  STEP  CONFIGURATION  EXAMPLE  OF  THE  DEVICE 

9.

USING THE WEBSERVER 

 
You want to connect a Siemens PLC to two Seneca Modbus RTU slave devices: 
Z-10-D-IN (SLAVE ADDRESS 1) and Z-10-D-OUT (SLAVE ADDRESS 2). 
 
In the example we will use the product Z-KEY-P (the steps are quite similar for the other devices R-KEY-LT-P 
and Z-KEY-2ETH). 
The 10 digital inputs of the Z-10-D-IN are from coil address 1 to coil address 10 of slave #1 device 
The 10 digital outputs of the Z-10-D-OUT are from coil address 1 to coil 10 of slave #2 device 
 

 

 
Now we use the Easy Setup 2 software and select Z-KEY-P: 

 
We add the first input of Z-10-D-IN to slave address #1 on serial port #1, to do this we select the device Z-10-
D-IN from the list and as resource INPUT1. Now rename the TAG to IN1:
