A-3-5 Initializing The Unit Operation Settings Of One Nx Unit; A-3-6 Reading And Writing I/O Data For Ethernet/Ip Slave Terminals - Omron NXEIP202 User Manual

A-3-5 Initializing the Unit Operation Settings of One NX Unit
This procedure initializes the Unit operation settings of one NX Unit in the EtherNet/IP Slave Terminal.
The unit number of the relevant NX Unit is 1.
The setting procedure is given in the following table.
Step
1 Change the write mode of the NX
Unit to enable writing.
2 Initialize the Unit operation set-
tings of the NX Unit with unit num-
*1
ber 1.
3 Restart the NX Unit with unit num-
*2
ber 1.
*1. The NX-series Safety CPU Units do not support the Initialize unit operation parameter object (service code 3D
hex). An error will occur if you execute the Initialize unit operation parameter object (service code 3D hex) for
an NX-series Safety Control Unit.
*2. An error will occur if you execute the Restart NX unit object (service code 35 hex) for an NX Unit that does not
support restarting. If this error occurs, restart the entire EtherNet/IP Slave Terminal (Identity object: 01 hex,
Reset: 05 hex).
A-3-6 Reading and Writing I/O Data for EtherNet/IP Slave Terminals
You can read and write the I/O data of an EtherNet/IP Slave Terminal using explicit messages from a
device that does not support tag data link (implicit message) communications.
When you use an EtherNet/IP master that does not support explicit messages, you can use the
TCP/UDP message service to read and write the I/O data of an EtherNet/IP Slave Terminal.
The procedure is given in the following table.
Step
1 Write the initial values of the out-
put data to the Units in the Ether-
Net/IP Slave Terminal.
2 Change the Units in the Ether-
Net/IP Slave Terminal to the Oper-
ational state.
3 Read the input data.
Write the output data.
