Omron OS32C, EIP warning zone change

[JureR 0]

Hi,

I have an OS32C-SN-DM Omron laser scanner on test and I am trying to set/read scanner parameters via Matlab, over TCP. The communication works as I am able to read the scanner range data etc. But I have a problem with changing zone set via Ethernet/IP (TCP) communication. I am using Omron OS32C Configuration tool 2.2.8 and the scanner OS32-SN-DM should support changing the zone set via EIP. In the Configuration tool I set Warning zone selection by EIP to Enable as shown in attached picture. The feature of changing the warning zone over EIP is explained in single paragraph:

4.21 Active Warning Zone Set Selection
When the scanners "Monitoring zone" is configured for multiple detection zone sets and the "Warning
zone selection by EIP" is enabled, the EtherNet/IP interface can be used to change the active warning
zone set instead of using the zone inputs. When this feature is enabled an EtherNet/IP network device
must select one of the 70 possible preprogrammed warning zone sets before starting normal
operation. For more information on zone configuration and selection, see sections "Zone Set Selection
and Configuration" and "Zone Set Input Selection" in the OS32C user manual. The switching time of
the active warning zone set using the EtherNet/IP interface is one scan cycle or approximately 40
milliseconds. Output assembly objects 113, 114, 115 each can be used to define the active warning
zone set as well as the vendor specific object 115 listed in Table 4.

 

I am using vendor specific object 115 (0x73,1,7) to change the Active Warning Zone Set, but the scanner is always in error code 70 (Incorrect number of active zone set
select inputs (guarded machine stop).

I tried with automatic mode, Start interlock mode etc, but the scanner always expects the digital inpuits to change the zone set.

 

Does anybody have any idea what could be a problem as the Omron local support does not know the answer.

Thank you very much for any suggestion!
