Configuration modes for digital inputs/outputs
3.1 Overview
Introduction
With the configuration modes for digital inputs and outputs, you can configure each channel
of the module as an input or output consistent with your application.
You use the available configuration modes to specify how the channels will be used:
• DIQ:
You can use each channel as an input or output through a corresponding parameter
assignment.
• DIQ with value status:
You can use each channel as an input or output through a corresponding parameter
assignment. Additionally, the value status gives you information about the validity of the
digital values and the channel status.
• DQ16:
All channels (0..15) are configured as outputs.
• DI8/DQ8:
Channels 0..7 are configured as inputs, and channels 8..15 are configured as outputs.
• DIQ MIX:
The channels 0, 2, 4, 6, 8, 10, 12, 14 and 16 have a fixed configuration as outputs, the
channels 1, 3, 5, 7, 9, 11, 13 and 15 have a fixed configuration as inputs.
Note
Project engineering configuration mode DIQ MIX
Note that you can only use the configuration mode DIQ MIX when configuring via GSD file
and in connection with the interface modules IM 157-1 PN and IM 157-1 DP.
Benefits
The address space occupied by the module is significantly reduced in the DQ16, DI8/DQ8 and
DIQ MIX configuration modes compared with the DIQ configuration modes.
This reduction offers you advantages if you have already assigned the available address space
of your plant for other processes.
