eneral:
The
NT2S-SF123B-EV2 is intended to be used as a low cost Operator
interface for PLCs which are rich in program memory or data memory
areas such as the Omron C Series PLCs.
The
NT2S-SF123B-EV2 has the following features:

Each key is mapped from work bits 201.00 to 201.05. Every time a key is
pressed, the corresponding bit as shown in the table below is held on while
the key is pressed. The keys also have alternate functions.

Put 03032E03H in words DM0213 and DM0214. The
NT2S-SF123B-EV2
will read data in DM0003 and embed in xx.x format.

Move “s “ into DM0215. This command completes the screen by
appending the “s ” to bake time.
This will put the following data in the data words below:

ar Graph:
NT2S-SF123B-EV2 uses DM0012 to DM0015 registers to hold bar graph
values to be displayed. If Offset register points to DM0200 then put
Hex value 0C0C into DM0200 onwards to display bar graph with the
value in DM0012.
Example:
Put 0C0C into DM0200, DM0201, DM0202, DM0203 and 200 into
DM0020. This will display bar graph 8 characters wide. Maximum
length is 16 characters. Each character on display can display five
vertical lines. To display full bar graph put # 80 into DM0012 and
0C0C from DM0200 to DM0207.
To display Bar Graph with value in DM0013, put 0D0D in DM0200
onwards.
R
egister mode:
In the register mode, the operator can access all the registers and bits
in the PLC.
By pressing the REG key, the operator can scroll through the register
prefixes. By using the UP / DOWN keys, the register numbers can be
accessed. Data can be changed in the registers by pressing the DATA
key. The data field will blink to indicate that the unit is ready to accept
new data. At this time, the UP / DOWN keys can be used to edit data
followed by the ENT key.
It is advisable to create a “password” screen which can block the usage
of the register mode.
