Creating and Registering Fixed Allocation Scan Lists

■
The method of creating and registering scan lists for fixed allocation using Programming Console
and a CS/CJ-series DeviceNet (Master) Unit is explained here. For details on operating Peripheral
Devices, refer to the operation manual for the Peripheral Device being used with the PLC. For details
on creating scan lists, refer to the operation manual for the DeviceNet (Master) Unit.
● Creating and Registering Scan Lists
Use the following procedure to create, register, and enable the scan lists.
In the following example, n = 1500 + (25 × unit number).

Clearing and Creating Scan Lists

Switch the operating mode switch to PROGRAM mode.
Enable the DeviceNet (Master) Unit functions. Set the DeviceNet (Master) Unit function enable
switch (bit 06 of word n) from OFF to ON.
Clear the scan lists. Set the scan list clear switch (bit 01 of word n) from OFF to ON.
Select the fixed allocation areas 1 to 3. Set the DeviceNet (Master) Unit's setting switch for fixed allo-
cation areas 1 to 3 (bit 00 of word n) from OFF to ON.
Enable the scan lists. Set the scan list enable switch (bit 00 of word n) from OFF to ON.
Switch the operating mode switch to RUN or MONITOR mode.

Checking the Normal Slave Table

Monitor the normal Slave table (words n+20 to n+23) and confirm that the corresponding bits are ON.
In the normal Slave table, the corresponding bits will be ON for the nodes that are communicating
properly.
Note With this Chapter's example system configuration, a value of 002E in word n+20 indicates nor-
mal operation.
