Setting the CPU Network Address
The DL240, DL250–1 and DL260 CPUs have built in
Direct
Net ports. You can use the
Handheld Programmer to set the network address for the port and the port communication
parameters. The default settings are:
• Station Address 1
• Hex Mode
• Odd Parity
• 9600 Baud
The
Direct
Net Manual provides additional information about choosing the communication
settings for network operation.
Setting Retentive Memory Ranges
The DL205 CPUs provide certain ranges of retentive memory by default. The default ranges
are suitable for many applications, but you can change them if your application requires
additional retentive ranges or no retentive ranges at all. The default settings are:
You can use AUX 57 to set the retentive ranges. You can also use
Direct
SOFT menus to select
the retentive ranges.
WARNING: The DL205 CPUs do not come with a battery. The super capacitor will retain the values in
the event of a power loss, but only for a short period of time, depending on conditions. If the retentive
ranges are important for your application, make sure you obtain the optional battery.
