11.5.4.3.3. The Rule for Assignment of Mapping Addresses for I/O Modules
Each module has two forms of data mapping. When DeviceNet master has not assigned the start input mapping address
and start output mapping address to AS01DNET (RTU), the contents in Input and Output in the following figure represent
offsets based on start input or start output mapping address of AS01DNET (RTU). After DeviceNet master has assigned
the start input mapping address and start output mapping address to AS01DNET (RTU), the contents in Input and Output
in the following figure represent mapping addresses of parameters in the modules on the right of AS01DNET (RTU).
When AS01DNET (RTU) is added to Scan List on the page of Scanner Module Configuration…, DeviceNet master
assigns start input and output mapping addresses to AS01DNET (RTU). When AS01DNET (RTU) is removed from Scan
List on the page of Scanner Module Configuration…, the start input and start output mapping addresses of AS01DNET
(RTU) are unknown.
Before the master assigns mapping addresses to AS01DNET (RTU), the device mappings of modules connected to the
right side of AS01DNET (RTU) are displayed as below.
