Step 3: Configure the Modules in the Remote Drop

In addition to configuring the Remote I/O Scanner, the Logicmaster 90±70 software is used to configure the modules in the remote drop, the rack type, and the Power Supply type. Configuration steps are the same as described in the Logicmaster 90±70 Software User's Manual.

When configuring modules in the remote drop, do not exceed the maximum configuration limits listed on the next page.

Configuring I/O Module Options

The module configuration screen also lists the selectable characteristics for that type of module. These include:

Input Filter: Allows selection of either 1mS or 10mS as the filter speed for all inputs on the board.

Output Default: Determines what happens to outputs on the board if CPU outputs are not received. Outputs may either be turned off, or hold their last state.

Voltage/Current Range: Selects the range over which the board operates (analog).

These selections can only be made using the Logicmaster 90±70 software. If a remote drop is configured (or reconfigured) using a Genius Hand±held Monitor, the I/O boards in the remote drop will operate in default mode only±±optional features cannot be selected.

The completed rack configuration will look like this example.

Configuring Reference Addresses

When you add a module to the remote drop by selecting it with Logicmaster 90±70, you can specify its reference address, or let the Logicmaster software assign the next available reference. Ordinarily, the module will be assigned to use references within the range configured for the Remote I/O Scanner. However, it is possible to assign an I/O module references outside that range. If that is done, the host CPU will not exchange data with the module. The module will provide data to the Remote I/O Scanner itself, or accept data from it, using the assigned references in Remote I/O Scanner memory. These references can be accessed by other modules in the remote drop, such as PCM, GDS, and ADS modules.
