• I/O Allocation Using Network Configuration Information
When using the 260IF as a DeviceNet master, the settings can be configured based on
the I/O sizes read from the slaves.
To read the I/O sizes from the slaves, use the network configuration information read
function.
For setting method details, refer to 6.1 Reading Network Configuration Information
in the MP920 Machine Controller User's Manual: 260IF DeviceNet (SIEZ-C887-
5.2).
If allocating I/O using the network configuration information, delete the I/O allocation from all the
slaves before performing allocation.
3.5.11 Local I/O Definitions
This section explains how to set Local I/O Definitions.
„ Outline of the Local I/O Definitions
The LIO-01 Module is equipped with 32 digital inputs (DI) and 32 digital outputs (DO). I/O
servicing is performed at fixed intervals, once for each high-speed scan or low-speed scan in
the MP920 CPU Module.
Four digital inputs can be used as interrupts by enabling interrupts in the Module Configura-
tion Definitions Window.
The Local I/O Definitions Window sets the scan timing and assigns registers to the discrete
inputs and outputs (16 of each) in connectors CN1 and CN2.
