Viewing the Adapter Status
Using Parameters
The following parameters provide information about the status of the
adapter. You can view these parameters at any time.
Parameter Description
04 - [RIO Addr Actual] The rack address used by the adapter. This will be one of the following
values:
• The address set by the Rack Address Rotary Switches.
• The value of Parameter 03 - [RIO Addr Cfg] if adapter Configuration
DIP Switches SW7 and SW8 are both set to ‘On’.
• An old address of the switches or parameter if they have been changed
and the adapter has not been reset.
06 - [RIO Rate Actual] The baud rate used by the adapter. This will be one of the following
values:
• The baud rate set by adapter Configuration DIP Switches SW7 and
SW8.
• The value of Parameter 05 - [RIO Rate Cfg] if adapter Configuration
DIP Switches SW7 and SW8 are both set to ‘On’.
• An old baud rate of the switches or parameter if they have been
changed and the adapter has not been reset.
07 - [Ref/Fdbk Size] The size of the Reference/Feedback. It will either be 16 bits or 32 bits. It is
set in the drive and the adapter automatically uses the correct size.
08 - [Datalink Size] The size of the Datalinks. It will either be 16 bits or 32 bits. It is set in the
drive and the adapter automatically uses the correct size.
13 - [DPI I/O Active] The Reference/Feedback and Datalinks used by the adapter. This value
is the same as Parameter 12 - [DPI I/O Config] unless the parameter
was changed and the adapter was not reset.
24 - [Switches] The status of the adapter Configuration DIP Switches. By default, all DIP
switches are set to ‘Off’ (enabled), and the adapter is configured based
on their settings. If both SW7 and SW8 are set to ‘On’, all hardware
switches, including the Rack Address Rotary Switches, are disabled and
the adapter is configured using values in the following adapter
parameters:
• Parameter 3 - [RIO Addr Cfg]
• Parameter 5 - [RIO Rate Cfg]
• Parameter 25 - [Start RIO Group]
• Parameter 26 - [Last RIO Rack]
• Parameter 27 - [Rack Size].
