Register 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 
or 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 or 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. 

 

 
 

Bar Graph: 

 

NT2S C

 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 5 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.
