Configuration 69
If the station is used in the safety-relevant portion of a GMR system, the
NIU’s Enhanced Diagnostics Mode parameter must be set to enabled.
When the NIU’s Enhanced Diagnostics Mode parameter is set to enable:
1.
Besides the NIU and the power supply, the only other modules
permitted in the station are analog input modules IC200ALG265
and IC200ALG266. There may be any combination of up to four of
these modules in the station.
2.
All of the analog modules must be located in the main rack.
Expansion racks are not permitted.
3. Empty IO carriers are not permitted.
4.
The NIU's Report Faults parameter must be set to Enabled.
5.
The NIU’s CPU Redundancy parameter must be set to GMR.
6.
The NIU’s “BSM Present” and “BSM Controller” parameters must
be set to No.
7.
The Report Faults parameter on every analog module must be set
to Enabled.
8.
The analog module in slot 1 must be assigned to %AI0001.
The analog module in slot 2 (if present) must be assigned to
%AI0017. The analog module in slot 3 (if present) must be
assigned to %AI0033. The analog module in slot 4 (if present)
must be assigned to %AI0049.
For each ALG module except the last one, one analog input
channel assigned to the station is not used. These extra/unused
channels still count towards the number of %AI channels the
VersaMax station will send to the Genius Bus Controller(s). The
table below describes the four possible configurations.
