[Example]
When number of ports used for input (I/O Parameter No. 14) =128 points, number of ports used
for output (I/O Parameter No. 15) = 64 points, number of remote resistor input words (I/O
Parameter No. 184) = 2 words and number of remote resistor output words (I/O Parameter No.
185) = 1 word;
(1) Calculation for Number of Remote Input Bits
Number of Remote Input Bits = 128 = 2 × 16 =96
(2) Calculation for Number of Remote Output Bits
Number of Remote Output Bits = 64 = 1 × 16 =48
(3) Confirmation of Remote Input and Output Domain Size
Remote Input and Output Domain => Number of Remote Input and Output Bits = 96
As shown in the figure below, the remote input and output domain (RX/RY) size = 96.
(4) Confirmation of Remote Resistor Input and Output Domain Size
Remote Resistor Input and Output Domain => Number of Remote Resistor Input Words = 2
As shown in the figure below, the remote resistor input and output domain (RWr/RWw) size = 4.
