2.1 Basic Configuration

JC-IO-N saves the read data from remote I/O for input signal to the internal register, and transmit the data to
the remote I/ O for output. This is called as I/O mapping.
Input signal
(Remote I/O)

2.2 Internal Register

JC-IO-N has 4 internal registers by data size.
Input (32bits)
Input (16bits)
Input (1bits)
Input (32bits)
Table 8. Internal Register
REGISTER BIT
L 32
S 16
B 1
P 32 -> 16
*The entire register is cleared to zero when the device is started up or when the setting is changed.
*Sampling (reading input signals) is performed in the order of L -> S -> B -> P.

A register to save 32-bit data.
Concatenate the two 16-bit data and handle as a 32-bit data.
256
In this case, set the upper/lower swap (SWAP) as necessary.
Set SWAP for the output in the same way.
A register to save 16-bit data.
256 Transferring upper 16-bit data or lower 16-bit data of L register is
possible.
A register to save 1-bit data.
512 Transferring the specified 1-bit in the L or S register is possible.
For output inverting the data is also possible.
Handles 32-bit data as input, and outputs differential value of previous
256 sampling as 16-bit data.
For input data, SWAP setting, same as L register is available.
