Checking Operations Section 2-5
I/O between Remote I/O
Terminals
Create ladder programs in the PLC of the Master Unit, and check that when
the switch on the DRT1-ID16 Input Terminal turns ON, the indicator on the
DRT1-OD16 Output Terminal turns ON.
Slave Allocations
In the system configuration examples in this section, Slave I/O is allocated in
the Master Unit’s IR Area for fixed remote I/O communications as shown in
the following diagram.
Displaying Temperature
Data with 7-segment
Display
Operation can be checked by displaying the temperature data input into the
Temperature Input Terminal on the 7-segment display (static, negative logic
model) connected to the Output Unit (IR 110) of the Master’s PLC.
The temperature data can be converted to BCD data by using the BCD(024)
instruction (when the temperature data is negative, it can be converted to pos-
itive data using the NEG(160) instruction). For details on using instructions,
