User manual OMRON NT2S-SF123B-E QUICK START

[. . . ] Thus Operator mode is a combination of Register as well as Screen modes. Screens : The unit displays 32 characters from the PLC memory. These characters are taken from the PLC data registers. The unit tracks register DM0020 ( the Offset register ) in the PLC. The number in DM0020 gives the start address of the data register block which contains the characters to be displayed. [. . . ] To do so, use hex bytes 0 to B (C to F used for Bar Graph) corresponding to register DM0000 to DM0011 respectively in the screen. Refer to the example given which explains the embedding of registers. It is possible to embed one data entry field in screens. It is similar to embedding register, only instead of 0 to F use 10 to 1F hex bytes to address DM0000 to DM0015. The registers DM0000 to DM0015 can be edited with this feature one at a time in a screen. Example 1: To display a static screen Suppose the following screen needs to be displayed on the NT2S C : Last Rinse Cycle Water pump is on To display this screen, do the following: a. Move number 200 in DM0020 since the screen text will be stored in DM0200 onwards. Move character string "Last Rinse Cycle" into 8 words from DM0200. In a similar manner, the characters "Water pump is on" can be embedded into 8 words from DM0208. from DM0208 to DM0215) This will put the following data in the data words below: Word DM0200 DM0201 DM0202 DM0203 DM0204 DM0205 DM0206 DM0207 ASCII Hex La st R in se C yc le 4C61H 7374H 2052H 696EH 7365H 2043H 7963H 6C65H Word DM0208 DM0209 DM0210 DM0211 DM0212 DM0213 DM0214 DM0215 ASCII Hex Wa te r pu mp i s on 5761H 7465H 7220H 7075H 6D70H 2069H 7320H 6F6EH Example 2: Embedding a variable in the screen Suppose the following screen needs to be displayed : Door: CLOSED BAKETIME: 13. 6s Suppose the bake time is available in data word DM0100 and the oven status is given by bit I001. 00. To display the above screen, do the following: a. Move number 200 in DM0020 since the screen will be stored in DM0200 onwards. Move character string "Door:" into 2 words, i. e. Move characters "OPEN" if bit I001. 00 is ON or characters "CLOSED" if I001. 00 is OFF. d. e. In a similar manner, embed the characters "BAKETIME: " into 5 words from DM0208. NT2S C uses DM0000 to DM0011 registers for embedding data. Here we select DM0003 to be used for embedding. So, move the data of DM0100 into DM0003 so that embedding can be done. Put 03032E03H in words DM0213 and DM0214. [. . . ] Example: Put 0C0C into DM0200, DM0201, DM0202, DM0203 and 200 into DM0020. This will display bar graph 8 characters wide. Each character on display can display 5 vertical lines. To display full bar graph put # 80 into DM0012 and 0C0C from DM0200 to DM0207. [. . . ]
