1-3 Communicating with the Host
1-3-1 Host Registration and Address
With NS-series PTs, data required for display can be accessed and the words and bits where the en-
tered data will be stored can be allocated to any area in the PLC.
The allocated words and bits are read from and written to directly, the display status changed for the
objects on the PT screen, and the PT status controlled or reported.
Communications with multiple PLCs are also possible with NS-series PTs. Host names are registered
for the connected PLCs and any area in the PLC can be accessed by specifying the host name and
address. Connect to the host using one of the following methods.
NS-series PT PLC
Timers/counters
DM Area I/O Area
Auxiliary Area
•
1:1 NT Link
•
1:N NT Links (standard, high speed)
•
Ethernet
•
Controller Link (When Controller Link Interface Unit is installed.)
•
Host Link
•
Temperature Controller Connection
•
Memory Link
•
Connection with PLCs and other devices from other manufacturers.
•
EtherNet/IP
Up to 100 registrations are possible for hosts.
Refer to the Host Connection Manual: Temp. Control, MemLink for details on Temperature Controller
connections and Memory Links. Refer to the Host Connection Manual: Multivendor Connection for de-
tails on connecting to another company’s PLC.
1-3-2 Ethernet
Hosts connected on the Ethernet can communicate with devices that support FINS (Factory Interface
Network Service) messages. FINS is a standard OMRON communications service. NS-series PTs can
read and write data, word contents, and bit status from supported PLC Ethernet Units without having
to be concerned about protocols.
The following PLCs can be connected using Ethernet.
CS1G/CS1H-E(V1), CS1G/CS1H-H, CVM1/CV, CJ1G, CJ1G-H/ CJ1H-H, CJ1M, CP1H, CP1L, CJ2H,
and CJ2M.
1-3-3 Controller Link
The Controller Link is an FA network that can send and receive large data packets among OMRON
PLCs and IBM PC/AT or compatible computers. The Controller Link supports data links that enable
data sharing and a message service that enables sending and receiving data when required.
The following PLCs can be connected using Controller Link: CS1G/CS1H-E(V1), CS1G/CS1H-H,
CVM1/CV, C200HX/HG/HE(-Z), and CVM1(-V2), CQM1, CJ1G, CJ1G-H/ CJ1H-H, CJ1M, CJ2H, and
CJ2M.
Note: The Controller Link Interface Unit is supported by the NS15, NS12, and NS10 only.
