Safety Configuration and Verification
Introduction
This chapter provides guidelines for configuring your safe speed monitor option
module.
Safety Configuration
When you configure a speed monitoring safety system, you must record and
verify the configuration signature and set the safety-lock status of the system
configuration. Though optional, you can configure a password to help protect
the system configuration from unauthorized modifications.
Configuration Signature ID
The configuration Signature ID is an identification number that uniquely
identifies a specific configuration for a safety option. Each time the system is
configured or reconfigured, a new configuration signature is generated to
identify that specific configuration.
You can view the configuration Signature ID by accessing the P10 [Signature ID]
parameter.
Safety-lock
When you have verified the operation of the system and recorded the
configuration Signature ID, you must lock the configuration to protect it from
modification.
You can lock the configuration by using the P5 [Lock State] parameter.
You can check the safety-lock status of the system by viewing the Configuration
Lock bit (bit 1) in the P68 [Guard Status] parameter. If the bit equals 1, the
configuration is locked. If it equals 0, the configuration is unlocked.

IMPORTANT
If you do not safety-lock the configuration, untested or unintentional changes
can be made to the safety option configuration, which could result in
unexpected system behavior.
