<Cause>

The lamp device memory is used redundantly.

<Solution>

Check if the same address as the lamp device memory is used in the screen data or in the PLC program.
Depending on the value set for [No. of Patterns], the number of device memory addresses used will vary. Check the availability of these device memory addresses.

Example: When five lamps (No. of Patterns: 3) are configured consecutively from lamp device memory M0000 (bit):

V-SFT Ver.6

V-SFT Ver.5


　OFF　　　 　ON　　 　　P3

 
     Wrong　　　　　　　          Correct

When "3" is set for [No. of Patterns], 2 bits are used.

L1 (M0000/M0001)
L2 (M0002/M0003)
L3 (M0004/M0005)
L4 (M0006/M0007)
L5 (M0008/M0009)

As the number of patterns is increased, the number of bits used is also increased.

L1 lamp example:

OFF display  M0000 : OFF, M0001 : OFF
ON display   M0000 : ON, M0001 : OFF
P3 display*  M0000 : OFF, M0001 : ON

* Since the higher bits have priority, P3 display is shown when M0001 is ON.
