Displaying Information About Bus Devices
Select F3 (Block/Bus Status) from the Analyze menu to:
HDisplay the references assigned to any device.
HDisplay the revision level of any device.
HDisplay the description and Global Data ad- dress of a bus controller.
HDisplay the fault status of a Genius block or Remote I/O Scanner (remote drop).
HSelect the active device.
HClear all faults on the active device.
HAccess the Bus Status display.
This screen provides a quick way to check for faults and forced circuits before starting up a system.
Line 1 also provides information about the device currently being displayed:
I= Inputblock
O= Output block
O | = Block with both inputs and outputs |
I |
|
A= Analog,RTD or Thermocoupleblock
G= PowerTRAC block or Remote I/O Scanner
Line 2 identifies the device and shows its serial bus address (also called its Device Number or block number), and its revision level.
Line 3 shows whether the device presently has any forces or faults. If the device is a Field Control BIU or Field Processor, however, the presence of faults is not indicated on this screen.
Block/Bus Status Displays for Bus Devices
Example displays are shown below. (Display format for bus controllers is shown on the next page).

Line 1 shows the I/O references used by the device. If * symbols appear instead of references, the device's references are incorrect for the type of host CPU currently set up for the HHM. For example, if a device is assigned to Series Six registers, and the HHM is set up for a Series 90 host, the HHM will display * symbols instead of references.
Selecting Another Device
Press F1 (Next) or F2 (Previous) as needed to display information about other device.
Note: Poor bus conditions may cause the HHM to skip (not display) a device that is present on the bus. Try moving the HHM to a different connector on the bus. Occasionally, this problem is caused by certain older Genius blocks that do not communicate with the HHM properly. If the problem persists, such blocks can be upgraded.
Selecting the Active Device
Initially, the active device is the one to which the HHM is connected.
You can display information about other devices without making them ªactiveº.
However, for many functions the HHM must be attached to another device or the other device must be made ªactiveº by following the steps below.
1.From the Analyze menu, select F3 (Block/Bus Status).
2.Press F1 (Next) or F2 (Previous), to reach the device's description screen.
3.When the device's screen appears, press F3 (Active) to make it the active device. (On a dual bus, the HHM must be on the same bus as the active block. If it is not, either move the HHM or force the bus selection)
4.Press D MENU to return to the Analyze menu.
