About NE1A-series Safety Network Controllers Section 1-1
1-1-4 Functions Improved in the Unit Version 2.0 Upgrade
The following table outlines the changes made in the unit version 2.0 upgrade.
1-1-5 Functions Added for Controllers that Support EtherNet/IP
For Controllers that support EtherNet/IP, the following functions have been
added to those of the NE1A-SCPU01(-V1) and NE1A-SCPU02.

and NE1A-SCPU02(-EIP)
Function Summary Reference
Logic operations
Program execution delay This function enables waiting for safety I/O communications to start
before executing the program. Even if this function is used, however, pro-
gram execution may start before safety I/O communications and logic
errors may occur for function blocks under some circumstances. This
function can be enable to prevent certain logic errors.

Function Overview Details
EtherNet/IP Communications (Tag Data Link) Functions
I/O communications The Controller can perform I/O communications as an EtherNet/IP target.
Not only specified I/O areas but NE1A-series Controller internal status
information and DeviceNet Safety I/O connection information can be allo-
cated in the originator.
SECTION 5
Explicit message commu-
nications
NE1A-series Controller status information can be read by services using
explicit message communications.
SECTION 6
Routing between DeviceNet and EtherNet/IP
I/O routing DeviceNet Safety I/O connection information can be routed to an Ether-
Net/IP I/O connection.
SECTION 5
Message routing Explicit message can be routed between DeviceNet and EtherNet/IP. SECTION 5
