Enter the specifications for the products to be added.
Enter the data on the input/output extension blocks and special function units/blocks to be connected
to the input/output powered extension unit, and calculate the current.
→
For data on the number of input/output occupied points and current consumption of each type,
refer to Section 6.8.
*1.
Input/output occupied points by special function units/blocks are excluded.
*2.
For input extension blocks (including FX
2N
-8ER-ES/UL, FX
2N
-8ER), do not include the current
consumption by the internal 24V DC. Subtract the internal 24V DC current consumption from the
service power supply of the
input/output
powered extension unit or the nearest main unit (except AC
power supply/AC input type) on the upstream side of extension power supply unit.
To connect a DC input type extension block to an AC power supply/AC input type main unit, it is
necessary to provide power to the extension block from an external source. Subtract the 24V DC
power supply current consumption from the internal 24V DC power supply of the main unit.
→
When the main unit is on the upstream side, refer to Subsection 6.5.1 and 6.5.2.
→
When the input/output powered extension unit is on the upstream side, refer to Subsection 6.6.1
and 6.6.2.
*3.
A maximum of 8 special function units/blocks are connectable, including the main unit and the input/
output powered extension unit.
