The GRT1-END-M Memory End Unit ensures a quick and easy replacement
of the GRT1-PNT in case of malfunction. The END-M Unit contains the Device
Name of the IO Device, which is used for the identification within the
PROFINET network. When configuring the PROFINET network, any Device
Name written by the Scan Tool of the IO Controller DTM to the IO Device will
be written immediately into the END-M Unit.
Be sure to execute the Backup function (see section 3-2-2 Backup function)
after setting the Device Name at configuration time and afterwards to enable
the Automatic Restore function of section 3-2-3 Automatic restore function. In
this way also a replacement of a malfunctioning GRT1-END-M can be done
without additional configuration actions.
At power-up of the system, the Device Name in the GRT1-PNT is compared to
the Device Name that is stored in the GRT1-END-M and updated according to
the following rules.
/i
Name in GRT1-PNT
(empty)

Name A
Name A
Note 1 Configuration with IO Controller DTM/Scan Tool is required.
2 This state will not occur when the Automatic Restore Function is enabled.
The GRT1-END-M Memory End Unit will allocate two bits in the PROFINET IO
Communication Unit's Input data area.

Bit Description
0 Device Name bit
OFF: the unit does not contain a Device Name
ON: the unit contains a Device Name
1 Reserved for future use
The GRT1-END-M Unit has two status areas. Each Unit's Status Flags are
turned ON and OFF based on the threshold/monitor values set for the function
in that Unit. A flag in the Communications Unit will be turned ON only when the
corresponding flag has been turned ON in one of those status areas.
The Communications Unit's Status Flag information is transmitted to the
Controller Unit. The
from a Programming Device.
The
SmartSlice I/O Unit
The Warning Status Area provides notification of minor errors detected in the
Unit.
When any of these flags goes ON, bit 2 of the Communications Unit's Status
Flags is turned ON and that information is transmitted to the Controller Unit.
