23 words Normal operation in which configuration data is sent for all 32 channels.

64 words. Configuration data and user-defined scaling is sent to the module.

An CIO instruction to configure a 1771sc-IFE32 module might be configured in RSLogix 5 ladder logic editing

software as follows:

CIO instructions, like Block Transfers, use a control data block. The Control Block for a CIO is a “CT” data type,

instead of a Block Transfer “BT” data type. The type of CIO which replaces a BTW is a “1771 Write”.

In this instance, CT13:0 has been chosen as the Control block for this instruction. The PU (Power Up) bit from the

I/O module has been used to trigger execution of this configuration block. The address of the powerup bit (N31:0/0)

assumes the module input and status data are being read into file N31.

In this example, we have chosen the basic Module Configuration data size of 23 words. The data in the source Data

File (N30:0 through N30:22) is entered by the user according to the 1771sc-IFE32 User Guide’s Chapter 4.

The Port Number of a CIO instruction is always 2, to designate the ControlNet channel on this PLC-5.

IMPORTANT: In our example, the 1771 I/O chassis is at Node 2 on the ControlNet network.

The 1771sc-IFE32 is in Slot 03 (starting from 00, so it’s the 4

slot in a single-slot addressed chassis). If the

incorrect Slot number is entered in the CIO configuration applet, the CIO instruction will return an error code F7

hex (which has a description “Unknown Error”).
