For a unused input circuit, short its "+" terminal to "-" terminal and also short one
of these terminals to its "Shield" terminal. An incorrect connection will make
input signal unstable and cause malfunction.
Use M3 terminals for crimping to the terminal block.
Terminals 1, 5, 9, 13, 17, 18, and 20 are not connected.
I/O allocation is necessary when using the Analog Input Module (±10 V, 4 CH). For
further details on I/O allocation, refer to 4.3 I/O Allocation.
