Standard Slave Function
4-6-1
Standard I/O Communications as Standard Slave
An NE1A-series Controller can function as a Standard Slave. One NE1A-
series Controller can function simultaneously as a Safety Master, Safety
Slave, and Standard Slave.
The NE1A-series Controller’s internal status information is also included in
the data allocated to the Standard Master, and so a monitoring system using
a PLC can be established.
The following steps are required in order for an NE1A-series Controller to per-
form standard I/O communications as a Standard Slave.
1. Creation of I/O data (slave I/O) to use as a Standard Slave
2. Registration in the Standard Master
3. Connection settings in the Standard Master
Standard Slave Specifications
Note
(1) The maximum data size is eight input bytes or zero outputs bytes when a
Bitstrobe connection is selected.
(2) COS and cyclic connections cannot be used at the same time.
(3) When two Poll/COS or Poll/Cyclic connections are selected, the same
output destination is used, so the maximum output data size is 16 bytes.
For inputs, up to 32 bytes of data can be set for 2 connections.
4-6-2
Creating I/O Data (Slave I/O) to Use as Standard Slave
The I/O data to be used for the DeviceNet Slave must be created in order for
an NE1A-series Controller to perform standard I/O communications as a
Standard Slave. The memory blocks for this I/O data are called Slave I/O.
