11.4.4 I/O Module Error Indication
When the Status LED flashes the controller status code 1 (i.e. a long flash, once every second), there
is a communication failure with one or more I/O module. To correct the problem, do one of the
following:
Ensure that every module contained in the Register Assignment Table is connected to the controller.
Check that the module address selected for each module agrees with the selection made in the
Register Assignment Table.
If a module is still suspect of having failed, confirm the failure by removing the module from the
Register Assignment Table. Download the changes to the controller. The Status LED should stop
flashing.
If a module is currently not connected to the controller, delete it from the Register Assignment
Table. Download the changes to the controller. The Status LED should stop flashing.
If unused modules must be intentionally left in the Register Assignment Table, the I/O error
indication may be disabled from a selection box on the Register Assignment dialog.
11.4.5 Register Assignment Checksum Error
When the status LED flashes the controller status code 2 (i.e. a short flash then a long flash followed
by a 1 second of delay), this indicates the register assignment is not valid. To correct this problem,
initialize the register assignment from the TelePACE software, or alternatively, perform a COLD
BOOT as described in the section 11-Operation of this manual. The status LED should stop flashing.
11.5 Configuration Switches
The SCADAPackl32 controller board SW1 is an eight position DIP switch. The first seven switches
on SW1 are used to configure digital / counter input filtering and analog input and output ranges.
SW1 is shown in the following diagram. Refer to Figure 1 for the location of SW1 on the
SCADAPack 32 controller board.

Configuration switches can be changed with the power applied. Configuration changes take effect
immediately.
To select configuration switch functions:
Remove the module cover and locate the configuration switches. See Figure 1 for SW1 location.
Slide the switch actuator to the right side of the switch to enable the switch function.
Slide the switch actuator to the left side of the switch to disable the switch function.
