RECEIVING NUMERIC DATA WITH GI[x] USING DI[x]

This procedure sets up communication using Group Inputs through Digital Inputs. This is a simple way to receive numeric data from another device in the field. Group Input 2 will be set as a 16-bit word. DI[33] to DI[48] will be used to receive the data. Digital Inputs must be configured as usual. This procedure is typical for Omron NX I/O block.

VIDEO TUTORIAL

STEP BY STEP

1. PRESS --> [ I/O ]
2. PRESS --> [ F1 ] [ TYPE ]
3. SELECT --> [ 5 ] 5 GROUP (see screenshot )
4. PRESS --> [ IN/OUT ] (If you don’t have the screen of “I/O Group In”)
5. PRESS --> [ F2 ] [ CONFIG ]
6. Using arrow on line GI #2, ENTER --> 89 in “RACK” column. (Corresponding to Ethernet I/P rack number).
7. PRESS --> [ ENTER ]
8. Using arrow on line GI #2, ENTER --> 1 in “SLOT” column. (Corresponding Slot of Ethernet I/P set up for this particular device).
9. PRESS --> [ ENTER ]
10. Using arrow on line GI #2, ENTER --> 49 in “START PT” column. (Corresponding Start bit of Ethernet I/P set up for Digital outputs) Remember, the first 16 bits are taken for Omron NX I/O block status.
11. PRESS --> [ ENTER ]
12. Using arrow on line GI #2, ENTER --> 16 in “NUM PTS” column. (Corresponding to the number of bits composing the numeric data. In this case, it is a 16 bits word)
13. PRESS --> [ ENTER ] (see screenshot )
14. PRESS --> [ FCTN ]
15. SELECT --> [ 0 ] 0 NEXT
16. SELECT --> [ 8 ] 8 CYCLE POWER (see screenshot )
17. PRESS --> [ YES ] (see screenshot )

End results : For instance, if DI[33] to DI[36] are ON, then GI[2] = 15 (0000 0000 0000 1111 = 15) (see screenshot )
