Using the Copy Configuration Feature

Once a Remote I/O Scanner has been entered into the PLC configuration, it can be copied to any other location on the bus. With the cursor at the module to be copied, press the Copy key. Move the cursor to the intended location for the copy and press the Enter key.

When the configuration of a Remote I/O Scanner is copied, the Logicmaster 90±70 software automatically increments the Remote Drop ID and the Reference Addresses for the copy to the next ones available. The configured lengths remain the same. For instance, if the first Remote I/O Scanner has been assigned to use 32 bits of %I memory, the duplicated configuration of the next Remote I/O Scanner would also initially assign %I memory the length of 32 bits. Like any of the other configurable parameters, this could be changed in the copied configuration.

When using the Copy feature, it is important to check reference limits. Once a reference type limit is reached, the Logicmaster software stops incrementing the reference address, and on successive copies the address ranges will overlap.

Using Reference View from the PLC Program Folder

In the PLC program folder, the Reference View function of Logicmaster 90±70 shows the Remote I/O Scanner as a single module. Individual I/O modules in a remote drop do not appear. In the example below, the two output modules listed are in rack 1, slots 3 and 4. They are NOT modules in the remote drop. Notice that their reference addresses are not within the range assigned to the Remote I/O Scanner.

The display shows the references assigned to the Remote I/O Scanner for the selected memory type. In this example, the Remote I/O Scanner is assigned references %Q00001 to %Q00064. It is within this range that the PLC will supply discrete outputs to modules in the remote drop.

Step 4: Store the Configuration to the PLC

After creating or editing a program folder, it can be stored to the PLC at any time. Use the Utility functions to store a program folder to the PLC, as described in the Logicmaster 90±70 User's Manual.
