9.4 Factory Settings and Reset Button
Factory Settings:
All EPM I/O Modules are shipped with a preset address and a baud rate of 57600. See the
following sections for I/O Module addresses.
Default Settings:
Sometimes a problem prevents an I/O module from running in its Normal mode. Problems
preventing normal operation are as follows:
• EEProm Failure
• Failure of Communication Settings Checksum
• Failure of Programmable Settings Checksum
• Invalid Communications Settings
• Invalid Programmable Settings:
• An Address outside the range of 1-247
• A Baud Rate not supported by the device
• Reset Switch triggered during Initialization
• Any modification to the Programmable Settings
• Calibration Mode (Analog Input/Output Module)
• Test Output Mode (Analog Input/Output Module)
When an I/O Module cannot run in Normal Mode, it will still run in Default Mode. If there is a
communication problem (or if you are unsure of a module’s address and baud rate), press
and hold the RESET button for 3 seconds: the module will reset to a default address of 247
at 57600 baud rate for 30-seconds. This enables you to interrogate the I/O using the GE
Communicator software; see the GE Communicator Instruction Manual for instructions.
When the I/O module is operating in Default Mode, the following happens:
• The device runs a 30-second timer. This timer is reloaded with every valid request
received.
• If the timer runs out, the device will reset.
• The commands used in Normal Mode will be ignored when received.
• Bits in the Device Status Registers reflect this state and the reason(s) for the state.
• The device will start in Normal Mode after reset, if nothing prevents it from doing so.
