General Information
Identification & Maintenance (I&M) provides a standard way of gathering information about an I/O device. The I&M information can be accessed by the IO Controller by means of acyclic Record Data Read/Write services.
The application should provide application specific I&M0 information during start-up. See PROFINET IO Object (F6h) for more information.
It is possible for the application to handle I&M records. Activate this using the IM_Options command. See Network PROFINET IO Object (0Eh) for more information.
While I&M0 information describes the application, the I&M5 information describes the communication unit i.e. the Anybus CompactCom 40 PROFINET IRT IIoT Secure, to the PROFINET network. Most of the information is provided by the module, but the application can change the order ID and the IM annotation (attributes #25 and #26, see PROFINET IO Object (F6h)). I&M5 is enabled by default, but can be disabled using attribute #27 (IM5 enabled), see PROFINET IO Object (F6h). If the example GSD file is used, I&M5 has to be disabled there aswell, se below.
Note
I&M5 is not available for Anybus IP. See below how to disable I&M5 in the GSD file for Anybus IP.
Default I&M0 information:
- IM Manufacturer ID
010Ch (HMS Industrial Networks)
- IM Order ID
“CompactCom 40 PIR”
- IM Serial Number
(unique serial number, set during manufacturing)
- IM Hardware Revision
(Anybus hardware revision ID, set during manufacturing)
- IM Software Revision
(Anybus software revision, set during manufacturing)
- IM Revision Counter
(Revision counter)
- IM Profile ID
0000h (Generic Device)
- IM Profile Specific Type
0004h (No profile)
- IM Version
0101h
- IM Supported
For submodules belonging to a “non–zero API”, the returned value is zero. For submodules belonging to API 0, the returned value is 000Eh (IM0-3 supported)
Disabling I&M5 in the GSD File
Note
I&M5 is always disabled and can not be enabled on Anybus IP. It has to be disabled in the example GSD file, if this is to be used.
I&M5 is enabled by default in the GSD file.
The settings for I&M are located at the Device Access Point, within <VirtualSubmoduleItem...>. To disable I&M5 , change GSDML entry <IM5_Supported=“true”> to <IM5_Supported=“false”>.
