Identification of Analog Input Values with Trigger Input
Both trigger input signals and analog input signals have time information. Based on their time informa-
tion, you can identify the analog input value that was read at the time of the trigger input. This enables
you to efficiently obtain the required analog input data.
Can be Connected to a CPU Unit or Communications Coupler Unit
NX Units NX-series High-speed Analog Input Units can be connected to the following Units.
• NX-series CPU Unit
*1
• NX-series Communications Coupler Unit*
2
When a CPU Unit and a Communications Coupler Unit are used together
, you can unify the methods
for installing, wiring, and setting up NX Units, and eventually reduce design costs.
NX Units: NX-series High-speed Analog Input Units
Example:
NX-series NX102 CPU Unit
NX-series EtherCAT Coupler Unit
*1. For whether NX Units can be connected to the CPU Unit to be used, refer to the user’s manual for the CPU
Unit to be used.
*2. The High-speed Analog Input Units can be connected only to an EtherCAT Coupler Unit.
Synchronous I/O with Refresh Cycle of the NX Bus
When the NX-series CPU Unit or EtherCAT Coupler Unit is used together with NX Units that support
synchronous I/O refreshing, the I/O control of multiple NX Units can be synchronized at the time to
synchronize with the refresh cycle of the NX bus.
This provides an accurate I/O control because it suppresses jitter in the I/O timing of multiple NX Units.
Simple I/O Wiring with a Screwless Clamping Terminal Block
The terminal block is a screwless clamping terminal block.
You can connect the wires simply by pushing the ferrules into the terminals. The amount of wiring work
is reduced without requiring the use of screws.
